Did anybody ever figure out (1) what "root" is or (2) how to get it working? I tried it, but the updater timed out waiting for a handshake from the radio. My guess is there's a sequence on the radio (e.g., a keyboard+power on sequence) that puts the radio in a mode that lets it be "rooted", whatever that does for you. A couple observations: - If reading from the radio doesn't work for you but everything else does, try running the RT76P program as Administrator; that fixed my reading problem. - If anyone comes up with a way to change the frequencies in a memory channel, that would be awesome. Without it, you can't, for example, put two GMRS repeaters on the same frequency but with different tones into memories [i live in a town with 7 million people; we have lots of GMRS repeaters], and you can't put a receive-only non-GMRS frequency in a memory. Both of those features are legal and would be very nice.
