Someone kindly contributed 152.0900 (146.2 PL) as primary for MROSD to the San Mateo County database last week. 151.23500 (203.5 PL) is still secondary.
I thought 152.0900 was a pager frequency, and the WQML377 license looks like a pager license in the FCC database. But, they are active on both.
Once you verify the new frequency, you might want to submit an update to database administrator for Santa Clara County.
