I seem to recall somewhere that there was at least 1 repeater site for .09 in that general area (some friends of mine in the CARA ham group were talking about this some time ago), but whether it's still there or not I don't know.
 Hmm, maybe not. According to the FCC query search
NRP hasn't been using 151.205 in the Baltimore Metro Area, but is using some of the new assignments. I hear NRP in Baltimore Co. being dispatched on 159.3825 Mhz DCS 731. I asked a source in the NRP about low-band, since haven't heard anything on 39.22 Mhz this year. They said low-band is going away and the NRP are going to all high-band. Didn't want to ask too many question, so that is all the information that I have for now.
