Every once in a while I have to be re-reminded about how useful APRS can be. I simply don't spend enough time fooling around with it to develop any level of proficiency beyond beaconing my location. APRS, like Winlink, can be used as a two-way communications tool between ham radio operators and non-hams, using some of the neat APRS-to-SMS or APRS-to-email tools that have been developed.
Looks like I'm going to have to invest more time in figuring all this out. Joe, I don't know whether to thank you, or curse you 😄
