For days now I have received encrypted comms from the DEA on 418.6250 nac 156 at the same time I am receiving encrypted comms on what I believe is the State Dept Security Service on 409.5250 nac 293.Anyone care to guess what is going on? It does not seem to be 409.5250 an input to the DEA ch 1. I am using a PRO 106 to receive with at my home 20 miles north of Boston MA.
