With Biden in a house that is white in dc, every time he does come to Rehoboth beach there is a USSS agent sitting in the lead patrol vehicle. One of the requirements is encrypted coms and with Del State PD now using encryption i bet they have been given a TG where the USSS and DSP can communicate with each other instead of having to give them a portable all the time. Also a programming computer can be set up at the Barracks and the trooper can connect his radio to that computer and follow the instructions on the screen to reporgram his portable or they should have the capability just to reprogram it over the air adding encryption.
