I have noticed every time I am in the area of Avon mountain, I get interference on the Plymouth police channel, sounds like digital noise, comes in short bursts pretty rhythmically. Just curious if anybody knows off the top of their head if someone shares that frequency, I thought maybe it could be some scada type thing due to the proximity to the reservoir

I believe there is an unlicensed user in Hartford on that channel. DMR XPT for the Civic Center.

That's it. XPT tunking. PL should keep it away but when Plymouth talks, it will likely overwhelm the more distant station.

Dont know what frequency is being used for them and what county that PD is in, but if there is a PL or DPL tone shown for them use that. It will eliminate hearing the DMR audio at least when the PD isnt talking. You'll still have some issues if PD and the DMR is on at the same.

Plymouth CT police in litchfield county 453.350. Radio is programmed with the DPL however when they talk this interference comes right over it (only when i am in the hartford area)

I actually hear that same sound on a couple of other channels as well. Usually named something random, so likely an incorrectly named frequency.
