I checked the following databases for that frequency (150.155 MHz) & nothing came up for: New York, New Jersey, Pennsylvania, Connecticut, Massachusetts, New Hampshire, Ohio & Vermont. It could be unlicensed. Any idea of the type of communications you are monitoring?

PL 110.9 150.155 NY State somewhere in the western part of the state.
Anyone know what it is? Can hear it when conditions are good from across Lake Ontario
150.155 is probably coming out of Canada. The 148-151 band is used by several groups, including business, public safety and paging services.
I know that before the BellNet P25 VHF TRS was installed a lot of Ontario Ambulances were in the 149-151 range. It could be what you may be hearing.
I did find a public safety agency using 150.155 - Peterborough County Emergency Services.
