You first made a claim that DMR is permitted on GMRS frequencies. The answer is still no, it is not permitted. Some limited form of digital data is allowed however, that much is accurate. Of course DMR will work on GMRS frequencies, but it is not legal. I agree that it would be nice, but not practical because of the sheer number of legacy analog systems already in use.

I have five DMR HT's from various manufacturers all of which work analog GMRS just fine. I also have four mobile DMR transceivers that will do analog GMRS as well as the intended amateur DMR VHF and UHF.

Hello everyone! i'm looking to integrate a Kenwood TK-880-1 ver2 with a repeater controller.... I'm about to pull the trigger on a pair or 880s and just wanted to do a bit more research before i do. On some other models like TK-805D, there is a way to open it up and solder some connections for the rx tx, ptt, tone, gnd, etc. (see link below) I can't seem to find anything on interfacing those.... wondering if the front RJ-11 would allow a custom cable? I'm going to most likely order a NHRC-3.1 controller so I'll have to make a custom cable anyway. Parts include: Kenwood TK-880-1 ver2 40 watt (or Kenwood TK-840-1 25watt) - both inside the GMRS band. NHRC-3.1 repeater controller NHRC-Squelch controller to be figured out later: antenna tuned for GMRS duplexer tuned for my channel cables I could also go with TK-840 - because i can also get a good deal on a pair of those. or maybe an older TK-805D because i found detailed plans on how to build the interface cable here: http://www.repeater-builder.com/kenwood/pdfs/tk-805-wiring.pdf I was looking to stay away from the 805 and 840 because the volume and ch knobs wear out, and become noisy. The 880 has a digital volume control and more features, so i think it would last longer, and i'd get more life out of it. plus, its a bit higher powered, not that i need that high of power anytime soon. any experience connecting the 880's or 840s to a controller? I'm leaning more towards the 880s, for a few $ more, the version 2 gives me 40 watts. but i'm not sure i need all that power, so i hope there is a lower 10 watt option for normal use. the 880 is hard to find details on, but i'll keep looking! Steve yes, i'm GMRS licensed.
