While traveling on 222 yesterday picked up a NEXEDGE 48 control channel on 451.05625. Looking up I came up with this license (WPKE440 (Radio Maintenance, Inc.) FCC Callsign Details) for Radio Maintenance out of Reading in Berks County. This came across with system ID L354. This channel showed as Site 1 with RAN 1 and a channel number of 1. No neighbour sites listed and didn't pick up any voice activity on here. If anyone in that area is able to run DSD+ and pick up any activity please share it here.
