Making Up My Mind

The XYL and I are planning for a long road trip - winding our way north to Michigan to attend a family wedding, then wandering back down towards Atlanta and visiting family along the way (many of them helpfully live just off of I-75). Normally when we camp, ham radio is a big part of the trip. Hours and hours of tinkering and making contacts while my wife reads or naps. This trip is different. It's like a military campaign. Get to Michigan as quickly and efficiently as possible, hang out with long-lost relatives and friends, head back with stops along the way to visit other long-lost relatives. We have a 22' pull-behind camper, but our overnight stays at any one place will be brief and, again, the focus will be on visiting with relatives, not stringing wire.

And yet, ham radio must play a part, even if it's a small one. On this trip the focus will be on back-up communications. I intend to take an HF setup that is small, efficient, easy to deploy, and I know works well on Winlink. The whole package - radio, antenna, power source, cabling, etc. needs to be as small and light as possible.

The antenna decision has already been made - Chameleon Antenna's excellent Tactical Delta Loop. It's fast and easy to set up, and versatile. If there's no space for the full delta loop deployment it can be configured as a simple vertical. The back-up antenna is a Par End-Fedz trail friendly EFHW.

But the radio selection process is more involved. I have something of an embarrassment of riches when it comes to rigs. I'd normally just toss my IC-7300 into a Pelican case and be done with it, but on this trip that radio (and case) would be too big. Something smaller is in order. Here's my options:

• Icom IC-705
• Elecraft KX3
• Elecraft KX2
• Yaesu FT-818

The IC-705 would seem, to most, to be the logical choice. It may well be, but the radio with all of it's necessary out-boarded components (like the AH-705 tuner) fits into a very chunky box. I'll admit though, in that chunky box there's a LOT of capability, and the 705 is a proven performer. In past write-ups I've called it a 'digital mode beast', and it is. Once you get it set up using a wi-fi connection between the rig and your computer, the thing will loaf along all day on digital modes and get only slightly warm. Icom did a remarkable job with heat management on this rig. 

Next, the KX3. This is the excellent Elecraft K3 desktop rig squeezed down into a surprisingly small package. What got left out was TX power. The KX3 puts out only 15 watts compared to the K3's 100 watts, but it retains all of the K3's world-class receiver performance. The KX3 overall is about the same size as the IC-705 but includes a built-in tuner and battery pack (although on internal batteries it only puts out between 3 - 5 watts). The radio requires an external soundcard for digital modes (I use an inexpensive Sbarent USB soundcard), but it's easy to configure and at moderate digital activity levels without getting too hot. I've installed an after-market heat sink, which helps. The KX3 with accessories fits into a Pelican case that is about 20% slimmer than the case the IC-705 fits into.

The KX2 is Elecraft's SOTA/POTA focused rig. They took the KX3, dropped 6 and 160 meter coverage, included a built-in tuner, lithium battery, internal charger, a built-in microphone and made it smaller and lighter than the KX3 by about 15%. Max output is only 10 watts, but you can actually achieve that for short periods on the internal battery. Yes the controls are cramped, but that's a reflection of the size of the radio. What Elecraft did retain from the KX3 is the large high contrast display. The display on both rigs is excellent - logically laid out, easy to read, and if you turn off the backlight, the radio sips just milliwatts on receive. No waterfalls, though. Like the KX3, this radio requires an external soundcard. The digital configuration is the same as for the KX3, but because of the smaller size of the KX2 it doesn't handle digital modes quite as well - it can get hot. But, for emergency Winlink use it's just fine. The KX2 doesn't get transported in a hard case. It travels around in a small soft bag.

OK, the Yaesu FT-818 is not a serious contender for this trip, but it IS available if I'm thinking of something for a back-up rig. My 818 has the Windcamp lithium battery mod, and that turns the radio into a viable emergency use rig. Plus, the little thing is so easy to use - it's probably the last honest radio Yaesu released, honest from the perspective that all the controls are logically laid out, the small display shows you everything you need to know, and not a pixel more, it's easy to configure, doesn't throw any surprises your way, and runs remarkably well on digital modes with an external soundcard. In fact, compared to Yaesu's later offerings like the FT-891 or the FT-991A, the FT-818 is a simple joy to use. 

So which is it? At this time I haven't made up my mind, so if you have any advice or suggestions let me know in the comments below!
