I did download APRSDroid, tried to get to work with my GMRS radio using my phone connected via APRS adapter that changes from k1 format to 3.5mm. Maybe I am missing something, I'll have to mess around with it a little more. I was trying to see if I could see the messages to show up through my GMRS radio to the GMRS Pro Radio. Just wasn't sure if there were other software to try like Xastir on a Raspberry Pi that might work. Figured this would come in useful in emergency conditions to get a message out quickly to someone listening along with GPS data etc. I am working on studying for Technician Class license but got my GMRS license couple of months ago and have been tinkering around with it.
