Same on this side I was doing the same thing with DSD+I switched antennas on one of my scanners that is hooked to DSD and it will not decode the signal. It is definitely bleed over from one of the Buffalo PD channels because I had another radio parked on 460.325 Buffalo PD and whenever they transmitted the noise bleed over was audible on 460.3125
460.3125 is associated with the NYS Thruway as Westfield & Batavia maintenance operations. It is usually busy during snow events as the snowplow drivers use it mostly.After monitoring Hamburg PD on 460.3375 all night. I found that 460.3125 had no activity. So anyone have any ideas, it seems no one so far thinks is the New York State Thruway Authority.
