Lol!
I have the 2nd Beta DMR load for my 436HP and CC and Slot is *all* I can get it to do. Decided to stop fighting with it and wait for the production version.
Saw the TRX-1 and 2 at Dayton. The 2 looks like their current mobiles. The 1 didn't look like anything they currently have, at least that I know of, but I don't know Whistler's products that well.
Another thing to consider is that Whistler has promised a NXDN update in the near future for their new radios. That would give you all but ProVoice (and D-STAR). Nothing from Uniden about NXDN, but they need to get their DMR stuff straightened out first, methinks. ProVoice, or lack thereof, is a consideration if you are near OKC, of course.
