So I noticed a flare up up people wanting to use digital data (the actually interfering kind) on GMRS locally, and the resulting backlash that it's illegal, etc. So I kind of dug into the Part 95 rules that specify that only certain handhelds on 462mhz are permitted to pass any form of digital data via simplex. So this leads to the big question, the elephant in the room per se... How does Digitally Coded Squelch pass muster under these rules, especially on 467mhz? I cannot find an exemption for it. Any DCS privacy code is literally a continuous 130+ bits per second data stream the radio broadcasts on the lower 300hz, which is continuous for the transmission duration. If there isn't an exemption, why is it permitted? And if there IS an exemption hiding somewhere (probably in another part?), what's to stop someone from further signaling digital data via alternating DCS tones? Seems like a blind spot in Part 95.

Basically Sevierville, TN. Decent repeater coverage but somehow two very powerful repeaters on line of sight mountaintops got shared tones and frequencies. One of them has strong audio and near instantaneous propagation, the other has weak audio (strong signal) and a slight delay on propagation. This lead to very garbled transmissions when they both picked up a signal and rebroadcast it. It actually took me 2 days to figure out what was wrong as prior commenters had also mentioned garbled audio. Pulled out the trusty SDRs and a couple of antennas and went hunting for interference. Only after I found an unexpected second repeater did I cross-reference MyGMRS and found it, updated 2 days ago. I found some other interesting things that I wasn't expecting, like someone running a Pirate DMR in apparently simplex (encrypted, no less!) on 467.725 in the nearby area.

So what's the correct way to address a repeater conflict? Where I'm at seems to have 2 active repeaters on 550 141.3 and any transmits are coming back heavily stepped on in the region between. Is there an official way to contact both owners that isn't going to offend them? WRJZ925 and WRFL895 EDIT: WRFL seems to have noticed my comment and deconflicted. PS: It seems like this would be a great chance for MyGMRS to do something really cool and check their database automatically for conflicts when new repeaters are listed. Don't know how complicated checking estimated range overlap would be, though.
