[Scan-DC] PGC public school question.

[Joseph M. Durnal]

RR often lists frequencies that are no longer in use.  Usually because they
are still licensed and if not, it is just hard to prove that something
isn't being used, the old prove the negative issue.  I like to think of RR
as a starting point and go from there.

I'm not close enough to PGC to really know.  In MoCo, the school security
is on the county Motorola trunked system, it is listed in RR and I have
heard them there.  In Frederick county Md, the busses and school resource
officers are on the county P25 but the schools themselves have their own
radios.  Some FMN and some DMR.

How to find them if each school is doing their own thing?  Well, if you use
something like unitrunker or other software with a couple of SDRs, you can
often find talk groups on trunked systems that aren't in RR.  For other
things, scanning, both the air waves and the FCC license database is the
way to go. When you do confirm, be sure to submit it to RR.
