I have been on the island when FLOTUS was on island and heard no Nantucket traffic on MSP Zone 4 which I monitor the cape and Troop D. I also heard nothing on MSP low band. I believe I have the 800 simplex channels in that bank but will need to double check that.
I am fairly certain that all state law enforcement agencies (MSP, MEP) operate on the encrypted NPD talk groups while operating on Nantucket but I can’t confirm this. If anyone can confirm the 800 simplex usage that would be great.
