I have been wondering this for a few months now. I have seen a Modern Rogue video where they had a HAM specialist on who demonstrated sending data using radio. That made me interested in using GMRS to try to send gemlogs to my father across town.
I've been trying to learn more on SDRs in general, and specifically Airspy, to hopefully help get a setup where I can use my phone to send him data, however I've only just really got into it so far. He's gotten way more into using SDRs to talk to people around the world, so when I get my tech license I'd like to look into doing it on HAM as well. I don't know enough about MURS, the only people that use it around me are Knott's Berry Farm's chicken restaurant, but it might be good to look at as well.
Some acronyms written out for anyone who doesn't want to go look them up:
GMRS - General Mobile Radio Service, one of the amateur radio bands, overlaps with FRS - Family Radio Service
SDR - Software Defined Radio - Essentially you took some of the hardware components of a radio, and made them into a software interface on a computer. Lot's of added functionality.
MURS - Multi-use Radio Service
Cool, if you have any progress keep us in the loop.
BTW in which country are you currently? I'm in MX, I think I should look first into the current laws for HAM.
