Damn. I've been playing with radios for years, and I have to say, these units are sweet. I've been trying to think of things that can be improved on them, and failed. The radios can do free-input text messages between units, and even allow a lead-in delay for sending 1200/2400 baud FFSK data through standard analogue repeaters. Best of all? It actually works.
So lets see, it's a Dual mode radio (Conventional/Trunking), 1000 channels, free form text messages, Voting, scanning, excellent RX sensitivity, great RX/TX audio, 25W output (selectable via software - no winding screws!). The actual unit is basically a huge DSP. I like it. Details of the units can be found here at TMC Radio's site. I'm still looking for things to pick on the radios for - so I can submit feedback for improvement, but it's not easy!
