464.9125 is almost certainly WQAQ385, AA Public Schools, licensed to
several schools in the glen burnie area among others.

463.7875 yes I believe that will be NEHS if you're in that area, same license

462.1375 is registered for a max ERP of 60 watts on the pole in millersville, same license - school security?

464.525 is definitely harbor, WPEX752

464.3875 MAY be AACPS as well under WRCU602, they have 50w max erp at crofton hs

461.225 definitely high point es

I can hear Shenandoah National Park on 171.700 NAC 4F9, from time to time, really loud, which is a good ways away. They were talking about clearing trees off the road earlier this evening, guess from all the wind they had out there. Pretty sure it's them anyways.

oh wow, surprised that was strong enough to get down there.

then again, fair enough 1676727168973.png

464.85 could be William E Gerber Inc under WRCH211, they're licensed for 110w (!!!) out of Towson. They're a USDOT registered motor carrier for garbage and recycling, so that's probably a good bet.

462.35 is probably sinai yeah, if you're anywhere near there WQBD728 1676727130764.png

for 152.33, armed with that info, I'm pretty sure that's Sheppard Pratt, WPLX994. That license is mostly their 100w stuff out of Towson 1676727435657.png but there is a simplex freq auth that's centered on their school in Lanham... I wonder if they have a mobile on that simplex freq there that's wired through to their DMR network.

These guys sound like they just drive around doing security in New Carrollton, pretty active in the evenings, alot of chit chat back and forth.

Sounds like transportation pickup. A lot of mentions of Zone 1 or Zone 3 for pickup. Maybe a university? Maybe UMCP (WPKS383)?

452.4375 - DCS431 - Maintenance? Mechanical?
Very active. I don't get good reception of the frequency.

Potentially Ports America Inc (WPPW807) or Mid Atlantic Terminal LLC (WQMB661)?
