I need some help if you have specifics for this frequency. We have George Washington University in D.C. using it with a PL of 74.4. Then we have a Baltimore facility - probably Johns Hopkins University or Johns Hopkins Bayview Campus - using it with a PL of 186.2. There is still another user that operates in CSQ mode. The downtown Johns Hopkins Hospital Security force uses 461.775 so we can rule them out as one of the JH users. The PL 186.2 user and the CSQ user are both Baltimore entities but that's all I've been able to discover about them. None of the users seem to transmit callsigns to make the job easier. Oh, and one user could possibly be Sinai Hospital since they are in the FCC database for this frequency too.
