I am well aware of the DTV issue that hits the 500mhz band in Delco as well as most other places in the Philly/NY metro area. After monitoring Delco Fire Dispatch and Fire 7 from Philadelphia and Camden County, NJ I also notice constant interference on those frequencies from the MotoTRBO system in Monmouth/Burlington County which shares those frequencies. Has that been an ongoing issue in Fire 7 territory around Ridley? At least dispatch has the alternative low band frequency. Yet I'm noticing an improvement on 508.2375 that it is consistently picking up from places it had not before in the last 6 months, apart from the interference issue. Was there a transmitter out that got fixed?
