The Northern California GMRS Users Group (NCGUG) has started to see an uptick in direct mode/simplex users on our repeater inputs over the past month. Some are not encoding tone, other are using 88.5, D031, D606, D172, and a few others.
Has any new programmable radio been released that is different than those that came before? Or one that ships with the 467 MHz uplink channels configured/configurable for Direct Mode?
This may also be a growing lack of understanding of these channels? As our repeater receiver is at 2,200 ft. AMSL, it easily hears handheld radio users within a 20-30 mile radius, and they can wipe-out our users when they are weak.
Occasionally they use one of our active codes, so their "discreet" (and likely unlicensed) comms are being retransmitted everywhere.
Normally such destructive interference was from heavily-accented maritime users at a nearby shipping port. But these new users are all english-speakers with little to no accent, with some minor exceptions. No callsigns are being used, and many seem to be unsophisticated radio users (which tells me some new radios are being sold with 467 MHz direct mode channels in them).
