Washington DC Logs

In the March issue of Monitoring Times, I have published my logs from the last trip I made to the Washington, DC area. I have a few entries that are unknown agencies, and like what I did with my New York City logs, I thought I would post them here and see if any DC listeners can help identify some of the unknowns. Any corrections or additions will be appreciated!

UPDATE: Check this post for updates, as I am adding information as I am able to find it.

USCG NET Updates

For a while now I've been tracking the new APCO P-25 digital radio NET channels being deployed by the US Coast Guard. I've posted what I've found so far, but recently received some additional channels and thought I would post the updates along with the known channels.

So here are all the VHF P-25 channels that we have identified so far:
