[Scan-DC] Anyone know who uses 462.5000 [ d155]?

Mon Mar 16 21:39:26 EDT 2009

It must by my week - APS is the private security service that  my section of Montgomery Village uses!  You're correct about them being at Washingtonian Center as well.  There is another guard service around here called Atlantic Security, I have them on 451.9.

Awhile back I did get the CTCSS for Riderwood's 452.5... I have it in my radio as 131.8, but I want to double-check that... I thought I had recorded it as 100.0; will get back to you.  I _think_ the other Riderwood channels use a different frequency.  The PRO-197 just this second captured APS's CTCSS as 136.5.

The APS units have a little "boop" at the end of their transmissions... have heard that on 462.5 also, I think... will have to look them up in the FCC database and see if they have more than one frequency... seems to me I have heard a security-type operation on that frequency on the BC-350 in the truck.  (I'm out of range of Riderwood here at home so I don't normally have the other frequencies activated.)

FWIW, I think it's Atlantic Security cars that I've seen on Inter-County Connector construction sites here in the Rockville area (Shady Grove Road and Redland Road).
