I am the proud owner of a new RFINDER M1. I have been getting into DMR with raspberry pi boards, and when I saw this android phone, I had to have one. After talking to the owner of the company last week, I got more excited about this thing. Its a big phone, and heavy, but I expect that given it rating and rugged build.
It has the RFINDER app, and PTT to run the radio. Also it works well with my BlueDV. More to come, I just got it today, and its a neat radio / phone. If you have a chance, look them up. Bob W2CYK was awesome on the phone and I cant wait to see what else these guys have down the road.
