F**king Up A Good Thing

(Language Alert)

For the past two days I've been struggling to get a new Facebook page set up and working the way I want it to as an information gateway for the ARES Southeastern US Situational Awareness Map. It's been a few years since I've set up a Facebook page. In the old days (say, before all this Metaverse crap), it was a straightforward process - throw some pictures and content into a standard (Classic) template, invite a few viewers and away you go.

But the Facebook page creation process has become so ridiculously complex and so stuffed full of bullshit like diversity virtue signaling settings and really, really crass revenue drivers ("Hey, invite your friends and make a buck off of them!") that it's a huge distraction, and you never really know just what's going on in the back end of what you are trying to build out.

As an admin you get pop-up crap like this all the time - on a simple informational page:


Sorry Zuckerbeg, but I'm not interested in pimping out my buddies for a few bucks.



I don't run a business and I'm not interested in posting my personal phone number for the world to see, and I have zero interest in WhatsApp.

I'm no newbie at this web development thing. I've either set up or admin at five very active Facebook sites, and I contribute heavily to others. I develop and run my own websites and, of course, this blog. In my professional life I manage almost a quarter million dollars of web development activity each year. I know what good web development tools and environments look like. The current iteration of Facebook ain't it. In fact, Facebook sucks at it.

The complexity of the FB page creation process is now mind-numbing, and a huge time suck. It's clear Facebook is pushing the platform further and further away from it's roots of simple page development and more towards a highly commercialized platform designed solely to vacuum up personal data for profit. Yes, Facebook was always like that, but at least they offered value in return - easy site creation and a fun place to hang out with friends who shared your interests. Now it's more professional developers, overly complex configuration, monetizing every damned mouse click, and virtue signaling all over the place.

I'm going to go looking for a different platform to achieve what I've been trying to get done. Right now I'm not sure if it'll be a blog or a web page. So stay tuned.

Deja-vu All Over Again

Or should this be titled Groundhog Day?

Hurricane Fiona tracked just offshore of Puerto Rico on Sunday, and wiped out virtually all power on the island and severely damaged other infrastructure. This is almost five years to the day that Hurricane Maria did her best to wipe Puerto Rico completely off the map.


There's a question and an observation here. First the question. Post Maria, the federal government pumped billions of dollars into Puerto Rico to help rebuild and harden the infrastructure. My question now is, what failed, and why? What did those billions buy? It certainly doesn't look like it bought any effective infrastructure improvements. I can understand some of the island going dark, or even a lot of the island going dark, but to have the entire island go dark should be raising red flags regarding infrastructure investment and how the money was spent. My suspicion is that, given the current political climate, those questions will remain unasked.

Now the observation. I've said this repeatedly, I don't care how good your infrastructure is, Mother Nature will have her way. Think about it - the entire island is without power. No phone, no internet, no lights, no clean water, nothing. Yesterday you were watching Game of Thrones and surfing the internet, today you're trying to figure out if your relatives in the village on the other side of the ridgeline are still alive. A total service outage can, and at some point will, happen. 

Are you ready?

Radios That Have Impressed Me

I've been a ham since 1995 (original call KC5YNP). I'm very serious about the hobby, particularly the hardware side, and I've been blessed with the opportunity to test a wide variety of gear. It takes a lot to impress me, especially first impressions. I don't do 'fanboy' reviews - there's plenty of that crap out on YouTube. I'll tell you how I really feel about a piece of gear only after I've used and tested it over a long period of time. I also evaluate hardware within its original design envelope - how good was it when it was first released, not how well it works today. Here's an example - I'm frequently surprised by folks who buy a newly manufactured Yaesu FT-818 and then bitch about how it's a poor performer because it's not an SDR, or has poor filter options. Well duhhh. It's a 23 year old design! You have to evaluate hardware in the framework of its original design and when it was released to market. In its day the FT-817 (predecessor to the 818) was a groundbreaking little rig (and yes, it's on my list).

So how do I evaluate? To be honest, most of my criteria are subjective. But in general:

  • A radio must be well built - it must be physically rugged and able to provide years of service within its intended use case. What this generally means is that things like HTs need to be more physically rugged than an HF rig designed to sit on a desk
  • Whatever features a radio offers must be well implemented. For example, if an HT is 2 meters only, that's OK, but the features in the radio - thinks like navigating menus, entering frequencies directly into the VFO, etc. - must be well implemented and easy to figure out. I shouldn't have to turn to a manual to figure out what should be easy and obvious
  • Manufacturer specific features need to really work, and work well, and add value to the overall package. For example, a well known (and respected) manufacturer adds a lot of proprietary features to their radios that only work with other radios of the same brand. Things like group calling, group alerts, etc (experienced readers will figure out what manufacturer I'm talking about). I view these as cute parlor tricks that have little value in the real world. If adding these features to the radio incurs additional retail cost, or squeezes out other more useful features then that's a no-go
  • Value for money. A radio needs to offer good value for money. I have a lot more respect for a manufacturer that leaves out some bells and whistles to keep the cost down, as long as the overall package performs well. 
There's also what I call the 'long term respect' factor. I've had radios that at first glance didn't impress me all that much, but after long periods of use I came to really respect them for one reason or another.

So without further ado, let's take a look at my list:

Icom ID-5100. The best dual band mobile rig I've ever used. This radio is, quite literally, my daily driver - I have it installed in my truck and it's been used daily for the past 3 years. I bought it for two features - DSTAR capability and the ability to do cross-band repeat. It does both of those spectacularly. I was so impressed with the first one I bought that I went out and bought a second for use in my shack. 
Why I like it: Dual receive, very well implemented command set, a well thought out touchscreen interface, easy to implement cross-band repeat, rugged. An outstanding value for money, even if  you don't use DSTAR.

Yaesu VX-6R. The sole survivor of Yaesu's classic 'rugged miniature' line of HTs that were very popular in the early 2000s. Just a simple, well implemented dual band (but not dual receive) radio in a small, rugged package. How rugged? I made a video once of me operating the radio during a tropical storm:


Why I like it: Rugged. Waterproof. Waterproof accessories. Well implemented command set. If you operate in wet conditions this is the radio to have.

Yaesu FT-60. The HT that refuses to die. For good reason. Perhaps the best all-around, basic dual band radio on the market. It's unpretentious, extremely well made, has an easy to navigate menu system (thanks to the full keypad) and offers excellent receive audio - something more modern Yaesu HTs seem to struggle with. I've owned two, sold one, and gave the other away to a new ham. Now I'm seriously thinking about buying a third while they are still available.


Why I like it: for all the reasons I list above - it's rugged (although not waterproof like the VX-6), has a well implemented feature set, is easy to manage thanks to the full keypad (backlit, by the way), has great audio, and has real and easy to manipulate knobs for things like volume, squelch and channel selection.

Icom ID-51. I bought this radio strictly for the DSTAR features, and as I struggled to figure out DSTAR I found myself not really liking the radio. My frustrations with DSTAR had colored my perception of the ID-51, and I rarely used it. Heck, I almost came to resent the thing. All that money for a system I just couldn't figure out. Then one day I picked it up to use for a public service event where I needed to be able to monitor two analog repeaters simultaneously, and was forced to actually use the radio in a real-world scenario. I quickly came to love it. Although it just recently went out of production (replaced by the ID-52) I consider it, in its time, to be one of the best dual-band, dual-receive HTs ever made. This little radio is now one of my 'daily drivers', and it's the one I instinctively grab when heading out to a park, or just to walk the dogs around the neighborhood.



Why I like it: The feature set and controls are well implemented, the monochrome screen is easy to read, the audio is outstanding. It's also one of the most ergonomic radios on the market - it just feels good in the hand. Plus, it's rugged. Icom never really highlighted this about the radio, but the ID-51 carried an IPX7 rating, meaning it was highly waterproof. It's a lightweight, rugged little beastie.

Icom IC-7300. The radio that has re-defined the mid-range HF radio. I own two of these (one bought used) and I run them hard on both voice and digital modes. Think 90 watts on MARS digital modes. There simply is no better HF radio in the same price class, period. The 7300 deserves all the hype that surrounds it. Even today, almost seven years after it's introduction, it sells by the boat-load. Literally, by the boat-load; Icom can't make enough of them to meet demand. My only gripe with the IC-7300 is that it does not have back-lit buttons. That's it. I know several hams that have one or more of these in storage as back-ups in case their 'daily drivers' go down. But the thing is, they never seem to go down. The reliability of the 7300 is one of its hallmarks. It's almost like Icom built a 200 watt rig and put it into a 100 watt box. Psssst - here's a little secret: the IC-7300 is actually a pretty good portable rig. It's really not that large, is fairly lightweight, is quite rugged, and as long as you keep it out of the rain and dust it'll do just fine in The Great Outdoors.

Today, the IC-7300 is the only 100 watt HF rig I unhesitatingly recommend to new and old hams alike.



Why I like it: Outstanding feature set, pretty good internal tuner, perhaps the easiest 100 watt rig to configure for digital modes, build-in sound card interface, excellent digital mode performance, outstanding filtering, great TX audio, excellent third party support. An excellent value for money, particularly if you can find a good used one.

Yaesu FT-818. This is one radio I don't use all that often, but I just like knowing that I have it. It's the low power Swiss Army Knife of ham radio. It does everything. Often not particularly well, but it does it all - 70 cm thru 160 meters, FM/AM/USB/Digital. The radio design is over 22 years old, yet it's still relevant. No other QRP rig on the market offers the features, quality and reliability that the FT-818 does at a similar price-point. It is the value-for-money champ. It's issues are legendary - a lack of any real filtering, poor frequency stability (improved somewhat in the updated 818 with the inclusion of a factory TXCO), a laughably archaic charging and power management system (again, that 22 year old design coming to the forefront), and a maximum of 6 watts output. But what you do get works wonderfully, in a package little bigger than a large paperback book. Yaesu did an outstanding job with the form factor - it looks and operates like a radio should! I've griped about the FT-817/818 (essentially the same radio) in the past, but I've also come to appreciate its performance, features and quirks. And now I can't imagine ham radio life without it. What's it's niche in my stable of radios? It's like this - when my wife and I go camping, I always put a lot of thought into what HF radio(s) to bring. The mix always changes. But after I'm done selecting, packing and loading all my radio gear, I've got the camper all ready to go, all the camping gear is loaded, the truck is gassed up, everything's hooked up and the dogs are in their places in the back seat, I always run back into the house, grab the Pelican case that holds my 818 and chuck it into the bed of the truck. Just in case...


Why I like it: Extremely versatile, well built, very well supported by third party software and accessory manufacturers, easy to operate and figure out.

Elecraft KX-2: The KX2 is what you get when a team of very talented electronics designers and  engineers who are also ham radio enthusiasts take the time to listen to their user community and design and build something to meet a very specific set of use requirements. The KX2 is so good at what it does it's almost scary. The radio is a QRP rig specifically designed for HF voice and CW. It'll do digital, but not nearly as well as it does voice and CW. It was also specifically designed to be small, light, easy to operate, and sip power so it can operate for long periods of time on relatively small batteries. And then someone asked, "Can we fit a tuner in this thing?" and next thing you know, the KX2 has one of the best internal tuners on the market. All in a package no bigger than a 1980's era 2 meter HT. But the icing on the cake is Elecraft's factory support. It is, far and a way, the best in the industry. What other manufacturer dialogs directly with their product owners through social media tools like Groups.io? I'm not talking about a designated corporate mouthpiece, but the actual designer of the radio, and one of the company owners? They will extend a helping hand regardless of how long you've owned your radio. I bought a very early production KX2, and I'm the third owner. I had some questions, and Elecraft happily answered my questions as though I had bought the radio new yesterday, and it was was still under warranty. I've written about my KX2 in the past, so I won't re-hash the issues here. Suffice to say, the KX2, six years after it's introduction, is still the best HF-only QRP rig on the market.


Why I like it: Excellent best-in-class HF performance, extremely small form factor, yet with a very well designed and easy to read display, an internal tuner that puts most other tuners to shame, an internal battery that will provide true 10 watts of output. The world's best manufacturer support.

Icom IC-705: Those that follow this blog probably figured I'd get here eventually. I won't say that with the IC-705, Icom hit it out of the park. But they did manage to put the ball squarely into the centerfield seats for a home run. I've written extensively about the IC-705 in this blog, and you can check out my posts by clicking here. The 705 continues to impress, and it's become one of my three main operating radios. That means it doesn't sit in a bag or Pelican case waiting for a POTA run. It is set up on my operating bench and gets used almost daily. In fact, I do all of my Winlink VARA testing and operations on the 705. Unlike any of my other QRP radios (KX2, 818, CTX-10), the 705 is a digital mode beast, and it is certainly no slouch on voice operations, either. I have two gripes about the 705, both of which deserve serious consideration by Icom. First is the radio's well documented lack of shielding, which makes the rig very susceptible to RFI, particularly over USB. The next is the form factor. The 705 tries to follow the Elecraft KX2 form factor, but the design team stumbled badly along the way. The form factor is just weird, the radio doesn't 'sit' right anywhere. It's an oddly awkward case design. But what the 705 does well, and overall better than just about any other QRP (or even 100 watt) rig is communicate. The front face of the rig is laid out like a miniature IC-7300, so if you are familiar with the 7300 or the IC-7610 you'll be able to set this rig up and start operating in minutes, without the manual. In typical Icom fashion, everything is well implemented and integrated. The build quality seems solid, although it does not carry any IP ratings. Like most new radios, there's still some question about the long-term reliability, but based on comments I've seen posted to the IC-705 Groups.io reflector and Facebook page, it seems to be holding up very well in outdoor use. Let's talk value-for-money. The IC-705 isn't cheap. Street price today is around $1,350. But when you compare its feature set with its closest competitor, the Elecraft KX3, the KX3 is more expensive and lacks many of the features the 705 provides. From this perspective I think the 705 actually offers quite a bit of value for its asking price.


Why I like it: Excellent overall performance on all modes, particularly digital, well thought-out control layout, excellent build quality, a very good power management system and surprisingly good battery life considering it's an SDR

Well, that's it for this list. If you have any questions or comments please post them below. Let us know about the radios that have impressed you the most over the years!

Cans

About half the time I'm operating on HF I'm wearing headphones. Usually it's because I'm participating in a formal net - MARS or SHARES - and I need to be able to hear and acknowledge all participants, even under tough propagation conditions. This means headphones. 

Like so many old-timers in Amateur Radio I've tried a huge variety of brands and models of headphones. All were good in some form or fashion. Some were really good - Heil headphone audio has always been universally good. I've owned some Bose and Sony 'studio reference' (whatever that means) headphones that were quite good, but they are designed more for listening to music than the spoken voice; too much bass and too wide of a response that can actually make voice communications sound 'muddy' to my ears. Great for listening to Beyoncé's latest over-produced off-key extravaganza, not so good for trying to dig callsigns out of the S7 noise floor.

Some of the best headphones I've used are not headphones at all. These are C. Crane earbuds. Crane builds them to emphasize voice communications, and they work great. They are my go-to 'headphones' for use with my radios during portable operations. The other good thing about Crane's earbuds is that they are cheap - about $20 a set. This means I can buy them in bulk so when my dog chews up a set I've got another sitting in the drawer ready to go.

But in my shack, when operating on HF, my long-time go-to headset is the classic Kenwood HS-5. 


Kenwood has been making these headphones probably longer than I've been a ham, and you can't get more old school; an on-ear design, vinyl covered dual spring-steel headband, lots of cloth sleeved wiring, and a long obsolete 1/4" single ring audio plug. Plop these on your head and your hand starts instinctively reaching for a CW straight key. They are that old school.

But the Kenwood HS-5 'cans' (an old time term for headphones) do two things better than most. First, they fit well. They may be a bit heavier than modern all-plastic headsets, but they are very comfortable on my oversized noggin. They balance well and you simply don't notice the weight. But most important, they sound great! Easily as good as any Heil product I've used, and perhaps a bit better. Kenwood set the response on these headphones to emphasize the spoken voice (vs. a broader response for 'studio' headsets). I hear voices on HF better with these 'phones than most others.

Some folks complain about the 1/4" plug, and I guess that's a valid gripe, but there's easy fixes out there. You can buy a 1/4"-to-1/8" adapter on Amazon, or you can simply clip off the 1/4" plug and solder on a 1/8" plug. But I don't want Kenwood tinkering with the design to 'improve' them. There's no updating necessary. These headphones are a wonderful homage to the days of classic ham radio, when you had things like external VFOs and tube finals, and they still work great in today's modern SDR world.

Highly recommended.

The View From The Bench - 06 August 2022

We're in what I'll call the 'post-Field Day, mid-summer ham radio doldrums', and for weeks now there's not been much ham radio stuff to report on. Down here in Gawga the weather has been hot, mostly dry, and buggy. Real buggy. So buggy that it's limited my outdoor operating activities. Then the XYL and I contracted COVID. While it didn't feel much worse than a mild cold, it did knock us back for almost two weeks, and we're still dealing with some lingering symptoms like congestion and coughing. Parallel to that, we launched on a major landscaping project to finally make our backyard habitable. What was supposed to be a little over a week job turned into a month-plus slog as the landscaper dealt with weather, material shortages and other demands on his time (he's a one-man show, so he works slow). Then a visit to the orthopedist for some nagging back issues threw me for a loop. What I hoped would be some simple muscle pain has turned out to be scoliosis, arthritis and a pinched nerve. That led to a canceled camping trip that we had both been looking forward to.

Slow progress, but progress


Getting old sucks.

So on to sunnier topics...

iPads 

Where I work (aka 'The World's Busiest Airport') senior management made a long overdue decision to go with a new maintenance management system. Part of this adoption will require provisioning the field crews with tablets that they'll use to respond to work orders and do inspections. The tablet of choice, and the one we steered them to, is the iPad. The software developer's apps just seem to work better on iOS devices. I'm not an Apple guy, but the XYL is. In fact, she's got a stack of old iPads sitting in a closet. Most of them were still perfectly serviceable, so I thought I'd grab one or two of the newest, update them, and use them to test and train on the new software. No such luck. The app requires at least iOS 15. The most current OS that could be loaded on any of these old iPads was iOS 14.x. The app wouldn't run. Damn. I needed to replicate exactly what the field crews were seeing on their devices so I could help train and troubleshoot, so an Android tablet wouldn't do. I needed an iPad, and I needed one fast. Double damn. After a few days of hunting around for the best deal, I settled on a new iPad Air. I found I could buy one on-line from the Army and Air Force Exchange System (AAFES) - one of the benefits of being an Army retiree - at a $200 discount and no sales tax.

Of course - of course! - the iPad got ham radio apps loaded on it. In fact, this is what the XYL suspected I really wanted it for. No honey, it's not. I had better uses for that money, plus I'm an Android and Windows guy (I love my Surface Pro). But I figure that as long as I've got the thing, why not try out some ham radio apps. My good friend Joe, KI4ASK, a long time Mac and iOS  addict/partisan/evangelist, has been singing the praises of a new iOS app for the Icom IC-705 (and IC-7610 and 9700) called SDR-Control for iOS. The app is written by Marcus Roskosch, who apparently designed the software interface for Flex radios, and a number of other highly regarded applications. I guess he knows what he's doing. I'm still in the learning stages with this app, but I have to agree with Joe, it's slick. While I can't say I'll ever use it for La-Z-Boy QSOs, I was sitting in said chair a few nights ago and just doing some SWL scanning while connected to my IC-705 via wi-fi . Lots of fun. I may have more on this at a later date, but for now I'll let Josh at Ham Radio Crash Course give you the rundown:


Antennas

I make no secret of the fact that I'm a Chameleon Antenna fanboy. What they make works, is rugged as hell, is well documented, and the company stands behind their products. A man has to have a vice, and since I don't smoke or drink (much), I decided my vice will be Chameleon antennas. Last  year Chameleon came out with their Tactical Delta Loop (TDL) and it caught my interest. The TDL was an immediate hit and Chameleon has had trouble keeping it in stock, but recently I found that the Atlanta HRO store had one available, so I grabbed it. I've used Chameleon's vertical antenna systems for years, but I was looking for a portable system that was quick to set up, didn't require ground radials, had more gain than a vertical, and could be rotated to take advantage of the improved gain. The TDL is an odd looking contraption - two 17' telescoping whip antennas set in a 'V' configuration (think giant TV rabbit ears) with a section of wire running between them. The antenna is fed at the base using one of Chameleon's standard matching transformers. The antenna kit comes with a ground spike to support it, but I've chosen to use my surveyor tripod, which gets the whole antenna setup further off the ground (improving the take-off angle a bit) and makes it easier to rotate. I've only tested it a few times, and only with my Elecraft KX2, but it seems to work quite well on 10 - 40 meters. The tuner in the KX2 easily finds matches on those bands, and can usually find a match on 75 meters, but it's a struggle. My real goal is to set this up with my IC-705 and test it with Winlink and JS8CALL. I think it has a lot of potential as an EMCOMM antenna.

Chameleon TDL set up for a local 10 meter net

Well that's it for now. I need to get back to my daily routine of fighting COVID, doing back stretches and praying for rain. I've been running the sprinklers so much on my new sod that I'm afraid to open my water bill. So c'mon Mother Nature, how's about a few days of light but steady rain? Pleeeze!

A Metaphor Of Sorts

Yesterday I stumbled on a YouTube video discussing a new vehicle that's coming to market, the INEOS Grenadier. The concept for the Grenadier was born of serious off-road enthusiast frustration with the lack of purpose built 4x4 vehicles that offered great performance with little fluff and at reasonable cost. I understand the turning point was the 2020 re-introduction of the Land Rover Defender, which is just an uptown 'lifestyle' schlepper better suited to the Kardashians than Katmandu. Land Rover devotees were disgusted with the new Defender concept and turned away in droves.

Not long after the Defender was announced, Jim Ratcliffe, the founder of INEOS and an adventure enthusiast, sat down with some buddies at the Grenadier Pub near London and sketched out the requirements for a true off-road vehicle. The result was the INEOS Grenadier. Based on what I read on-line and find posted on YouTube, the vehicle is getting very strong positive reviews, especially from the Australians, who take their off-roading seriously. According to reviews the Grenadier gets just about everything right:
  • A design that emphasizes ruggedness, off road mobility, reliability and survivability
  • Only a very minimum of 'bells and whistles'
  • Powertrains optimized for rugged off-road performance
  • A conscious selection of lower tech options (ex: coil spring suspension vs suspension air bags) to better fit the vehicle's mission requirements of reliability, mobility and survivability
  • Virtually zero accommodation for 'lifestyle' options: entertainment systems, built-in wi-fi, seat-back entertainment systems, etc.
  • An easily modifiable design
  • A serious effort to keep the whole package reasonably affordable
In the Grenadier's latter development stages, INEOS directly solicited public input by shipping pre-production examples around the world and demonstrating them to off-roading enthusiasts and the automotive press, something that's almost never done in the automobile industry

The INOS Grenadier. When Land Rover screwed up, INEOS stepped up

So what's all this have to do with ham radio? A lot, actually.

How much money have you spent on Icom, Yaesu or Kenwood products over the years? If you are like me, the answer is 'thousands'. Have you ever been contacted by a rep from any of these companies and asked about the features you'd like to see in a new radio? Have you ever offered your input at hamfests and had it seriously considered? Has a manufacturer's rep ever asked for your contact information so they could get back to you for more input? I'm guessing... no.

If you are an outdoor enthusiast, and like to play radio on a mountaintop rather in your ham shack, how many IP67, or even just IPX3 HF radios do you own? How many carry a MILSPEC ratings for ruggedness? Sure, today we can buy small portable HF radios like the IC-705, the Yaesu FT-818, or the Elecraft KX2 or KX3, but how many would survive a light rain shower or a short fall from a park bench?

The feature laden Icom IC-705 is the ham radio equivalent of the 2020 Land Rover Defender. Very capable but packed full of fluff, sporting awkward ergonomics, and so expensive that many owners are afraid to take it outdoors.

How about a radio built with user input, that leaves out all the fluff, delivers top notch voice and digital performance in an all-in-one package, and can take a licking and keep on ticking? 

What ham radio needs is its own version of the INEOS Grenadier.

ARES Southeastern US Situational Awareness Map

This is a bit of a coming out party. So, noisemakers and party hats all around!

Last month I put up a post about the Situational Awareness Map, highlighting some changes I had made, and some future plans. Well I'm happy to announce that the map is now out of beta development and is available for general use. A lot of the changes are evolutionary, not revolutionary. But the changes and improvements are significant enough that a quick overview is warranted.

Perhaps the biggest change is that the map is now focused on the entire southeastern US, not just Georgia. I've talked with key users of this map for some time and the thought is that a regional focus makes more sense; weather systems and radio signals don't respect political boundaries, and we are often called on to support our fellow ARES members in adjacent states. But how do we define 'southeastern US'? Well, the most logical way is to follow FEMA, and use FEMA Region 4 as the definition. This makes a lot of sense since organizations like SHARES, DHS, CISA, NOAA, the Army Corps of Engineers and other federal agencies structure their disaster response frameworks in relation to FEMA regions. So FEMA Region 4 it is!

Other key improvements come in how the map (data) layers are structured in the map. Data structure is tightly focused around individual states. This give each state the ability to focus/display only the data pertinent to their states. There is a lot of regional/national data in the map, but that's only for map layers that by design must span the region. The best example is NOAA weather radar. This is a national-level data feed and it is impossible to segregate it out by state.

Another serious issue that is starting to push to the forefront is map performance. At this time there are over 45 separate data layers in the map, everything from severe thunderstorm warning polygons to PSAP 911 service areas. Every data layer, even if it's turned off, imposes a performance penalty in the map. Let's use the HIFLD fire/EMS station dataset as an example. This is a national-level dataset with tens of thousands of point (station locations). Before the map can display just fire stations in state of Florida it must first pull across the entire dataset, apply a dynamic filter against the data to select just fire stations that fall inside of Florida, apply a complex symbology rule against those points and then dynamically display them in the map so the fire station symbols remain the same size regardless of the zoom level the user selects. That's a lot of work to ask a web browser to handle. Multiply this one example by 45 or so data layers and you start to understand why map performance is an issue that must be carefully managed. This map is starting to push the performance limits of what Chrome, Firefox and Edge can reasonably handle. For that reason I've imposed some rules that users need to be aware of:

  • With the exception of the Severe Thunderstorm Warning and Tornado Warning polygons (provided by NOAA) all other data in the map is turned off by default. When the map opens, it opens to a blank screen that shows just the state and county outlines. It's up to the individual user to tailor the map to his/her needs by turning on the data layers they want. Therefore it's very important that you review the available map layers and practice turning layers on/off
  • Requests to add new data layers will require some serious justification from the requester. You will have to provide a compelling operational need for the data layer you are requesting. Remember, every data layer imposes a performance penalty. During real-world events like hurricane disaster response I'll add whatever data is needed without too many questions, but for non-operational use I'll have to be very selective about what gets added
  • Data layers that don't get used will get dropped. I can track individual data layer requests, and if I see a particular data layer just isn't getting used, especially if it's a national or regional layer, it'll get deleted from the map
A few days ago I held the first training/familiarization presentation on this new map, and using Google Meet's new recording functionality I was able to save the presentation to YouTube. Although the video is long (about an hour and eight minutes - sorry, I like to ramble), it provides a good overview of most of the features in the map. I encourage you to view it, and feel free to use it as a presentation for your own ARES and EMCOMM meetings.

If The Big One Hits, Be In Syracuse!

Last month the Antique Wireless Museum released a 1951-era industrial movie made by General Electric that highlights how the city of Syracuse, NY used mobile radio for disaster response after a nuclear strike. Conveniently, General Electric's mobile radio division was headquartered in Syracuse, so this is really an early version of an infomercial. But it's a well done infomercial, and actually tells a useful story about how to create what we call today an emergency operations center, or EOC.

I'm surprised at how little has changed in terms of EOC operations between 1951 and today. Today we have fancier communications systems, software, computers, the internet, smartphones, and better looking firefighter helmets 😄, but most of the basic roles and functions we have in an EOC today were there in 1951. From that perspective the movie is quite interesting.

What I particularly liked was the use of  an early 'GIS' (geographical information system) - a map table with push-pins around which all coordinating activity revolved. Today we have fancy computer-based GIS systems, but paper maps and pushpins are still in wide use. It's still a very effective way to maintain situational awareness. 

I was also really struck by the emphasis the movie places on Amateur Radio as an integral part of any emergency communications system, and an integral part of EOC operations. Quite impressive, really.

So have a seat, strap on your way-back goggles, and enjoy EOC operations as they were over 70 years ago!

Something Interesting From Yaesu

Everyone else is jumping on the prognostication bandwagon, so why not me?

Yesterday the word came out that Yaesu is releasing a new HF rig in August. Called the FT-710, it appears to be about the size of the Yaesu FT-991A, but it's HF only (no UHF/VHF capability). Now, the 991A is no diminutive little mobile rig, and the 710, based on the announced specs, is actually just a smidge bigger all around, so this isn't a SOTA rig by any measure. Some have observed that this is likely Yaesu's newest 'entry level' SDR rig, and is likely designed to go head to head with the Icom IC-7300. That sounds about right to me, because the radio incorporates Yaesu's newest SDR technology (which is getting great reviews). What little we know of the feature set so far looks good:

  • High resolution touchscreen interface
  • Build-in tuner
  • A DVI port on the back (for out-boarding the digital interface)
  • Two USB ports. 
  • SD card slot 

What's NOT been released yet is any mention of a built-in soundcard interface. However, Yaesu makes mention of a 'Preset' mode for things like FT8, and since you need a soundcard to run FT8 I'm guessing the soundcard interface is there.

The things I don't see but would like, beyond the soundcard interface, are:

  • Built-in GPS, and a GPS synched internal clock
  • Some level of industry standard environmental protection such as IPX5
  • A set of factory rack handles (a-la the IC-7200) would be nice, but if not I'm sure Portable Zero will be right along with a set
  • Yaesu traditionally 'gets it' when it comes to back-lit buttons (Icom? Icom? Icom?). Let's see if they continue the tradition
So far no power consumption numbers. I don't expect this thing to sip juice like the FT-817. After all there's a (relatively) power hungry digital interface in the mix. But Icom has proven with the IC-705 that digital interfaces and low power consumption are not incompatible concepts. Maybe Yaesu has incorporated some clever power management protocols and options into the radio. We'll have to wait and see.

The last thing I would ask for would be for Yaesu to please, for the love of God, clean up your awful configuration and settings interface. And please, don't make the dumbass mistake you made with the FT-891, and not provide an easy way to quickly switch between LSB and USB.

Chip Shortages - Still?!

 Thomas Witherspoon posted this a few days ago on his (excellent) SWLing Post blog:


Silly me. I thought we were about out of the Great COVID And Fire-Induced Chip Shortage Of 2020 - 2022, but I was wrong. I guess if the current administration can blame everything else on Putin (Putin's Price Hike, Putin's Inflation, Putin's Food Shortage, Putin's Baby Formula Shortage, ad nauseam), we can blame this current round of chip shortages on him, too. And actually, according to Thomas, there may actually be something behind blaming Putin for our current and ongoing chip shortage issues. It seems Russia and the Ukraine are the primary sources for several strategic minerals used in chip production. So we'll call this Putin's Chip Shortage.

I've got a wide assortment of shortwave receivers. Heck, just about every Amateur Radio HF transceiver I own is a top-notch shortwave receiver. But I'm of the age and stage where dedicated shortwave receivers are still fun to collect and play around with. Down through the years I've had some pretty good ones. The collection starts with a 1950's era Grundig tabletop model with the dial gloriously laid out not just with frequencies, but with the names of the exotic location where signal originate from - London, Berlin, Moscow, Tokyo. Spinning the dial was a trip around the world. And the collection reaches all the way to the present era, with the diminutive and remarkably good C.Crane Skywave SSB.

The one portable receiver I had that always brings back memories is the Sangean ATS-909 (also sold by Radio Shack as the DX-398). 


Based on reviews of the radio in publications like Passport to World Band Radio (sadly out of print, and badly missed), I picked up an ATS-909 just before heading back to Germany in 1998 for my second tour of duty there. At the time Central Europe was still a 'shortwave rich' environment, with powerhouse broadcasters like Voice of Russia (the old Radio Moscow), Deutsche Welle, and the BBC still pumping out content on shortwave. Additionally, I knew that many of the German FM broadcasters were switching to RDS, making the ATS-909's RDS decode capability a neat and useful feature.

While I can't say that the ATS-909 was a stellar performer on shortwave - most outlets rated its performance as just good to very good - the radio's build quality was outstanding and the ergonomics were excellent. Plus, it's performance on FM was considered best-in-class. That radio served me well in Germany, going along on a number of field exercises so my Soldiers could listen in on American Forces Network (AFN) broadcasts, local German stations, and the occasional radio show from the BBC. After the factory radio was stolen from our Volvo V70, the Sangean ended up doing service as an ersatz car radio. It slid perfectly into the gaping hole left in the center console where the Volvo radio used to be, and served well until I could get another radio installed. The ATS-909 eventually just gave up the ghost, too much time spent being rattled around in the car and sitting in the Georgia summer heat. I regretfully tossed it after the alkaline batteries belched up their contents in the battery compartment. I also kicked myself for not picking up one or two when Radio Shack closed them out a few years later.

For the past year or so I've been following the story of Sangean's replacement for the ATS-909, the ATS-909X and the 909X2. The ATS-909X was considered something of a disappointment - a bit deaf on shortwave reception when using the whip antenna (but a strong performer when using an external antenna), and some problems with AM sensitivity. The ATX-909X offered Sangean's usual excellent build quality and ergonomics, but with strong competition from lower cost mainland Chinese manufacturers like Tecsun, Sangean knew they needed to clean up the 909X's shortcomings (Sangean is a Taiwanese, not a Chinese manufacturer - there is a difference). So Sangean tweaked the ATS-909X's performance and renamed it the ATS-909X2 - just in time for chip shortages and COVID to hit. Talk about timing.


Reviewers really liked the improvements in the 909X2, but production was slow and prices for the radio, if you could find one, were high, with some retailers asking over $500. In the past six months production has increased, and the radio's price has settled down to about the $250 US level. Amazon now has regular stock of the radio and can deliver in a day or two.

But what about the lingering chip shortages? Some manufacturers like Icom have been very frank in their discussions about the impacts of the shortages. Production goes to the high demand/high volume customers like computer, military and commercial communications systems and automobile manufacturers. Low volume customers like ham radio and shortwave receiver manufacturers get low priority. This means the price and availability of the any radio - Sangean, Tecsun, Icom, Yaesu, Eton, Panasonc, etc. is in question. With this in mind I decided to go ahead and pull the trigger on the Sangean, and I placed an order with Amazon a few days ago.

A side-by-side comparison with the ATS-909X2's competition will have to wait. I've got several portable shortwave receivers to test against - the C. Crane Skywave, the Skywave SSB, the Tecsun PL-880, the Tecsun PL-310 and maybe one or two others hiding away. I'm particularly interested in seeing how well the Sangean performs on SSB compared to the PL-880 and the Skywave SSB, two radios that get high marks for sideband reception.


One thing became abundantly clear to me in the few hours I've used this radio so far - the ergonomics and build quality are outstanding. Anyone who's spent any time with a portable SW receiver will find the controls clearly marked and well laid out. You don't need a manual to get up and running with this radio (but if you do, the manual is excellent).


Sangean includes an external wire antenna, ear buds, and something few other manufacturers provide - a 'wall wart' power cube. The radio runs off of four AA batteries and can use alkaline, NiMH and NiCad chemistry types.


A word about external antennas. Many manufacturers, including Sangean, include an external antenna with their radios. Many folks feel that a portable radio shouldn't need an external antenna. For commercial FM and AM broadcast reception, I agree. But for shortwave and ham radio reception, an external long wire antenna is absolutely necessary. You wouldn't expect your expensive Amateur Radio HF rig to operate well on 80 meters using a 3' whip antenna. Why would you expect a consumer-grade receiver to do better?  Be realistic. If you buy a portable SW/HF receiver also pick up (or make) an external antenna to use with it.

OK, let's wrap this up. Over the next few seeks I'll be doing a side-by-side comparison of these radio on the Amateur Radio bands, focusing on 75 and 40 meter sideband reception. I'll be looking at overall performance, ergonomics and form factor. All the evaluations will be done using the factory supplied long wire antennas. Will a clear winner emerge? Stay tuned!

Message Center Clocks

I love clocks and watches, and I've written about this in the past. I also love to research and read about the history of radio, particularly radio operations involving two way communications (as opposed to broadcast radio, which is one-way only). It's clear that radio and time are inseparable. Just about everything in radio revolves around time. Our formal nets start and end at defined times. Much of our software like WSJTX and JS8CALL is tightly time dependent. Modern military and, increasingly, commercial transceivers are dependent on accurate time signals to synchronize things like frequency hopping, automatic link establishment, and automated digital messaging operations. Time is everywhere in radio. Has been since Guglielmo Marconi first thought about commercializing his 'invention' back around 1900.

My earlier post was about radio room clocks, particularly those that call out the mandatory quiet periods at 15 and 45 minutes past the hour. These clocks were designed specifically for maritime radio room use - a reminder to the operator to cease transmission for a 3-minute period and just listen on 500 kHz for any distress calls.

But there was another use for clocks in conjunction with radios, a use that was somewhat more utilitarian but just as important - in military message centers.

First, let's define what a message center is. A message center is nothing more than one or more radios dedicated to transmitting and receiving message traffic. If you were in the military for any length of time, particularly if you worked a job that involved coordinating activities at a brigade or higher headquarters, you'll have heard the terms 'comms (communications) center' and 'message center'. A comms center is an over-arching communications environment that handles both direct voice communications and message traffic, while a message center is dedicated to handling just digital or voice message traffic - orders, reports, etc. When a commander wants to talk by voice to one of his subordinate commanders he goes to a comms center. When he needs to send a report to his higher headquarters he goes to a message center. The difference between the two was often very fuzzy, particularly at the lower battalion and company levels, where one or two radios were handling ALL voice communications and message traffic duties. But at higher command levels, with steadily increasing volumes of message traffic, a dedicated message center was usually required. 

And, of course, message centers needed clocks. Everything was coordinated by time. Radio message traffic needed to be time-stamped and logged with the time received or sent. Operators needed to know when to switch frequencies to handle message traffic on different nets. They needed to time-track when physical messages (paper copies) were received or handed off. Basically, everything in a message center revolved around time.

It was during WWII that the concept of a purpose-built message center clock took hold. There may be earlier designs, but if there are I have not seen them. My my guess is that prior to the WWII era militaries just used whatever cased clocks they could procure. But starting with the run-up to WWII (which, remember, started in Europe in 1938 - a full 3 years before the the Japanese bombed Pearl Harbor), a few militaries like the US and Germany started specifying designs for message center clocks. Let's start with the US. The Army took the smart and easy path, and asked manufacturers like Chelsea, Hamilton, and Lowe to make a variation of the maritime 'deck clocks' they had been making for years. The first clocks were brass cased, later switched to a phenolic (Bakelite?) housing to conserve a strategic metal that was in short supply. The movements in these clocks were fairly rugged, simple to service, and were already in volume production. All the US Army had to do to make them 'army' was to have the words 'Clock Message Center M1 (or M2)' stenciled on the face. The M1 models had 4" faces, the M2 models had 6" faces, and most seem to have come with a secondary 'zulu time' hour hand. The Army had them mounted in a clever flip-open wooden box, which made them easy to transport and set up.

WWII and clock cases were quickly switched to a phenolic (Bakelite?) case


The far more common M2 message center clock (6" face) in a phenolic housing. 
The red hand is the 'zulu' or second time zone hand

These clocks were a commodity item, produced in the thousands. If they appear in period photos at all it's because the photographer was taking a picture of something else and the clock just happened to be in the shot. Here's one of the best known (and clearest) photos of a message center clock in use. This photo is interesting because it looks like the radio is being used in an early M2 or M3 Scout Car. Note the telegraph key strapped to the operator's leg, and the home made speaker box. I'd guess that this picture was taken either pre-war, or immediately after the US entered WWII. This is a great example of what a 'message center' looked like in small units during the war - a single radio, a single operator, a clipboard with some standard message forms, and a clock.


Some have asked, why not rely on wrist watches? A good question. We have to remember that prior to WWII a good quality wrist watch was a fairly expensive consumer item. Not everyone owned one. This was almost half a century before the arrival of cheap but accurate quartz watches. In the 1930's and 40's all watches were hand assembled mechanical units that could cost a working man's weekly wage, or more. Plus, the US military can not compel soldiers to use their personal property for official purposes - which means they can't compel you to buy and use a wrist watch as part of your Army job. If your job requires a watch, they'll issue you one. However, it's cheaper to provide a single clock that's available for all to reference than hand out a bunch of wrist watches. Then there's the issue of time synchronization. All activity in a message center had to be referenced to a single time source. If everyone is using their own wrist watches, and each watch is off a minute or two in either direction (very common with mechanical watches) then how are you sure that Message A arrived before Message B? In wartime this matters, a lot.

The German Army took a similar approach. Called a 'funkuhren' (radio operator clock), it was a standardized clock specifically designed to be used in message and communications centers. However, their clocks were a bit different - they appear to be large pocket watch movements in a modified case with a larger mainspring, giving an 8-day runtime. The whole thing is mounted in a wooden case, and the movement can swing out for winding via a  knurled knob or stem on the rear. Actually a pretty good arrangement. since it doesn't require a winding key like the American clocks do. 





Evidently this design was so good that the Germans kept it in production after the war for issue to the new Bundeswehr communications units. I can't help but wonder if there's a warehouse full of these things somewhere in Germany, in unissued condition, waiting to be dumped out onto the collector market at reasonable prices. One can only hope...

Note the 'funkuhren' on the table in the lower left. This German soldier is running a Hellschreiber unit.
 You can still run Hellschreiber using digital mode software like Fldigi, and it's a lot of fun!

Note the 'funkuhren' on the table between the two radios

So we've looked at US and German message center clocks from WWII. What about the British, French, Japanese, Russians, Canadians, etc? Honestly, I don't know. I've never seen any write-ups or on-line discussions of message center or radio room clocks in use by other countries involved in the war. I can only guess each country had some sort of standardized timepiece they adopted.

Now let's push forward to today. As a MARS and SHARES member I run a small message center. So I need a message center clock, right? OK, it's just for looks and tradition, but to me it's important. I'm always trying to connect the past to the present, so we don't forget.

Chelsea, the US company that made the majority of message center clocks in WWII, is still making pretty good reproductions. Not exact replicas, but considering the cost of a good working Army surplus M1 or M2 clock, they are good enough. In a nod to modern times and cost, these clocks use battery powered quartz movements. They also still use the same phenolic cases that Chelsea started using in WWII, but now they are made of a more up-to-date glass reinforced plastic. Overall they are pretty good clocks, and have a place in even the most modern of ham radio shacks.

by the US Army as 'Clock Message Center M2'

A modern Chelsea 'radio room' clock. I like this one for it's accurate quartz movement and 'zulu'
or second time zone hand

But I have to think that the Germans did a better job of it, particularly for smaller setups. The Chelsea M2-style clocks are big. Six inches may not sound like a lot, but when the clock is sitting only a few feet from your face, it's a bit imposing. The smaller 4" M1 message center clocks would be a better option, but nobody makes a replica, and originals are very hard to find. The smaller German 'funkuhren' clocks seem like they were better suited to small setups. Sadly, nobody makes a 'funkuhren' replica, and good working examples go for silly high prices. But the idea that a large(er) pocket watch format can serve as an ersatz message center clock has me intrigued.

And I think I've spied my solution, courtesy of Seiko. It's the Seiko SNE370 wrist watch. It's not as large as a pocket watch, but at 43mm it's it's plenty big enough. It's got a clean, uncluttered face with a 24 hour inner ring, and it's got an accurate quartz movement. I can do without the day/date readout, and I'd love a second hour hand (a 'zulu' hand or, as it's called in the watch world, a GMT hand), but you can't have everything. One problem though... it's out of production. Aaarrrgggghhhh! I can't catch a break.

Decisions, Decisons

The XYL and I are beginning preparations for a week long camping trip later this summer. Of course radio will be part of the adventure. The question is, which radio(s)? If I look at the goals I have for this trip (beyond campsite setup and tear-down, meal prep, entertaining the XYL, walking the dogs, entertaining the dogs, feeding the dogs, general camper maintenance, shopping, talking with camper neighbors, sightseeing, etc, - those of you who camp know what's involved), the things I want to do with radio include:

  • chasing DX
  • POTA activations
  • Winlink
  • JS8CALL
  • MARS
  • SHARES
  • testing & playing with ALE (Ion2G)
Of course the IC-705 is in the mix. It's become my default camping radio. It can easily handle the DX, POTA, Winlink and JS8CALL duties, but at a low TX level (max 10 watts). 


But for MARS and ALE I'll need a different rig. I've got a number of MARS modded radios - IC-7300, Yaesu FT-991A, IC-7100, IC-7200, even my Elecraft KX2(!), but only two are suitable for ALE operations - the IC-7300 and the IC-7200. Both of these radios bypass the band relays when scanning in 'split' mode. This means as the radio scans from band-to-band while running ALE you don't hear the 'clack-clack-clack' of the mechanical band filters switching in and out. The 7300 does this out-of-the-box, and my 7200 has the 'quiet scan' mod which achieves the same result. 

IC-7300. The all-around champ in my radio stable

IC-7200. Not as capable as the 7300, but a good bit more rugged

Almost as important as the radio is the antenna selection. The campsite is a bit cramped, with 'neighbors' close-by. I won't have space to string a 120' end-fed, or even an 80' dipole. I always have a Chameleon end-fed EMCOMM II with me, just in case, but for high power HF I'm likely going go have to rely on a vertical. Problem is, most modern campsites are awash in RF hash generated by any number of consumer devices that campers bring along, from LED light strings to portable generators. A vertical is precisely the wrong type of antenna to use in that environment - they attract electronic noise and hash like a magnet attracts iron filings. I have a magnetic loop, which is electronically quiet - mainly because it's so narrow banded - but it's only good up to 25 watts on sideband, even less on digital.
 
Vertical HF - occupies relatively little real estate, but attracts interfering RF
like a magnet

Mag loop antenna - quiet and effective, but can only handle 25 watts

I guess I've got some testing and planning ahead of me. Oh dear, how will I manage?

Situational Awareness Map Updates (June 2022)

 As many of my readers know, I publish and maintain the Georgia ARES Situational Awareness Map. This map is a project that goes all the way back to 2016, when Georgia ARES was looking to improve the quality of repeater data in the state. At first the map was just a front-end to a project called the Georgia ARES Repeater Database Initiative. The repeater database initiative was seen as a way to get repeater owners to submit and update their own data, thereby improving the overall accuracy and reliability of repeater information. The map was created simply to show repeater distribution across Georgia, but was very quickly added to and improved. By 2019 the map had moved far beyond its original purpose, and had morphed into a situation awareness tool.


As with any web-based product or site, changes happen with regularity. New data layers become available, old data layers are pulled off-line. The development platform itself changes over time; the technology base that the map is built on undergoes revisions and updates. New capabilities are added, performance improvements are introduced and security vulnerabilities are fixed. I'm lucky in that the technology platform I use - ESRI's ArcGIS Online - is updated quarterly and they are always bringing new capabilities and features to the web mapping environment. The Situational Awareness Map has undergone at least three major changes in five years, as ESRI has updated the underlying platform. It's the latest change that I'll be discussing here.

The map has been moved to a new environment called Experience Builder. Experience Builder is a highly configurable web mapping environment that gives the developer a wide variety of tools and options to pick from, without having to write any code. While I could have hung on to the older development environment for a while longer (it will be decremented over time), there is capability in Experience Builder that I've been waiting years for ESRI to introduce. So, over to Experience Builder we go!

I have also decided to close down the associated Georgia ARES Repeater Database initiative. It's had a good run, but participation has fallen off and it's no longer worth the effort to keep it going. For repeater data I now rely on Repeaterbook.com. The owner of Repeaterbook.com, Garrett Dow, KD6KPC, has been extremely gracious in giving me permission to include his repeater data in the map at no charge. 

I'm also broadening the focus of the map. Until this update the Situational Awareness Map was entirely Georgia-focused; it was as though Georgia was an island unto itself. However, we are often directly influenced by what happens in other states, particularly when it comes to weather. Some ARES ECs, particularly those that serve counties that border other states, have asked that I extend coverage into these neighbor states. That process was started with this update, and I now make county and repeater data available for Alabama, Florida, Tennessee, North Carolina and South Carolina.

The map also takes advantage of a new feature I call 'layer groups'. In the old map, there was no way to group related data layers (say, 70 cm, 1.5 meter and 2 meter repeaters) under a single heading. This resulted in an overly long and complex data layer listing that was difficult to navigate. The new layer grouping feature makes finding data layer much easier, and provides a cleaner, simpler layout. 

Expandable and collapsible layer groups
 makes navigating data layers much easier

Other enhanced features or new data in the map includes:

  • The ability to generate elevation profiles - line of sight between two points - directly in the Situational Awareness Map. The capability is available in the function 'widget' bar at the bottom of the map (the line of blue circles). In the past this capability was only available in a separate application, but I've been able to incorporate the feature directly into the map
  • Georgia repeater coverage heat mapping (under the Repeater Planning Coverage layer group). This layer provides repeater density-based heat mapping to help evaluate repeater coverage 
  • Under the Situational Awareness Infrastructure layer group, I've added Georgia Dams (Safe Dam Program) managed by GDOT, and I've re-added Beach Webcams. The camera layer is what I'll call 'fickle' - these are cameras installed and maintained by commercial activities like resorts and hotels. Camera feed availability can be spotty, particularly during hurricanes or coastal storms. If the camera feed is up and operating, great. If not, well...
  • Under the Transportation layer group, I've added GDOT 511 Events - a point layer of major traffic issues, mainly related to long-term construction activities. I've also brought in a more up-to-date GDOT traffic camera feed - GDOT 511 Cameras
  • Under the Hurricane / Tropical Storm Response & Management layer group, I've added the national data layers for the NOAA Storm Surge (SLOSH) Data. SLOSH stands for Sea, Lake, and Overland Surges from hurricanes and storms. These layers help visualize coastal areas that will be inundated in each of the five hurricane categories 
  • Under the Grids layer, I've added the Georgia State Patrol GSP Aviation SAR Grid. This grid divides the state up into roughly 16 x 19 mile grid squares used to coordinate aerial search & rescue activities
That's it for the major updates. As I mentioned earlier, this Georgia map will be taking on a larger regional focus over time. Recently I was contacted by the Maryland Section Emergency Coordinator to see if the Georgia Situational Awareness Map functionality could be extended to the mid-Atlantic states. The project is in the works, and has the support and involvement of ARES leadership from Maryland, Delaware, DC, Pennsylvania, New Jersey, Virginia and West Virginia.


The point here is that if you are an ARES or EMCOMM leader in one of Georgia's neighboring states - Alabama, Florida, Tennessee, North or South Carolina, now would be an opportune time to ask about a situational awareness map specific to your state. Just drop me a line at w8byh@arrl.net.
