With All do respect ….this should not be a race To reveal…..should be race to be discreet. Listening is a privilege.

Actually it is (or was) a guaranteed right in US Code.

I had the freq in record mode for 2 days and haven't heard anything since Thursday. I don't even know if the surv was near me or somewhere else. The VHF High band had a lot of ducting during the time I heard the operation. It was definately 167.9 pl analog; 2 units watching a house and then following a vehicle. Nothing heard that would tell me where they were at. Freq: 169.5375 sounded like a simplex freq.

169.5375 167.9 is NIFOG NC 1 / IR 5 (Repeater/Simplex), a federal interop frequency, so that could be any agency.

Neat. I haven't heard Fed analog in over 20 years.

Yes, very neat! It is getting rarer, and rarer now. Still a little in National Forests, Federal Aircraft in firefighting on VHF, and "some" interagency operations, and on calling chans in the fed/non fed i/o, and in the NFIOG. Enjoy it where you find it.

The National Forests that have switched to digital are mainly in the eastern U.S. I don't think interagency wildland fire will be switching to digital anytime soon, if ever. This is due to the all or nothing aspect of digital modulation. Often times a signal can be copied on analog when it is buried in noise.

FEDS are regular users of the Analog and P25 Federal channels available (See the NIFOG) as are the Locals (Part 90 licensees) for the Non Federal channels
