Has anyone else heard Control Channels on 391.0625 and 392.6625 MHz? Thanks! Someone told me it might be a TETRA TRS, and it could be in Baja.

I cant listen to those freqs on my scanner I cant get the 300 band freqs.

Just tried those 2 freqs but not hearing a thing from El Cajon.

weird, that's a satellite band

I did not know that. I had only heard military aircraft, and still do, in this range. More info on the U.S. use of this frq. range:

No wonder my garage won't open!

Ya, maybe a re-allocation.. I was looking at a spectrum chart several years old.. Plus the mil can do whatever they want anywhere they want...

380-400 has been reallocated, and is no longer military aircraft. It's now military trunking systems, and also military in-squad radios (the military version of FRS radios... in fact, they use a custom variant FRS retuned to their channels in this range.

The (ICOM) Intersquad radios use:

CH-01 396.8750
CH-02 397.1250
CH-03 397.1750
CH-04 397.3750
CH-05 397.4250
CH-06 397.4750
CH-07 397.5500
CH-08 397.9500
CH-09 398.0500
CH-10 399.4250
CH-11 399.4750
CH-12 399.7250
CH-13 399.9250
CH-14 399.9750

There are quite a few military trunking systems going in all over the US in the 380 range, we certainly have one at Miramar, with a control channel of 385.350, and I believe there are several more around southern california. The BC396T will handle these trunk systems, though they are generally supposed to be encrypted once fully installed and gotten working. So far, I don't believe the Miramar one is using encryption. (They are P25)

There continues to be AM military aircraft in the 380-400 Band, and will continue. I have to lock them out while searching for NFM TRS activity. Hearing them this last week in Calif. and Colorado.

It takes a while for the 'word' to percolate through those hard military skulls.

They've been told to vacate, but that doesn't mean they've remembered to change EVERY frequency list out there. The Coast Guard changed its channels, but still uses the old 'prohibited' ones occasionally.

Eventually, one of the old users will interfere with a new, authorized one, and it'll hit the fan, with the military given some firm instruction to get with the orders they've been given, and NOT use that range for its old uses.

Heard today:

380.200 So Cal Approach Control

385.400 So Cal Departure

387.025 So Cal Approach/Departure
