Default Military use of P25

I've been away from monitoring the military for awhile. I see several frequencies listed as P25. Are these typically encrypted, or are some in the clear?

It all depends on the system, the only way to know for sure is to throw them in your radio and scan you'll find out pretty quick if it's encrypted. Also if you give us your location that may help us identify what systems are around you and someone who has better knowledge of those systems may be able to chime in and better help you.

I'm in Macomb Township/Macomb County Michigan. My new BCD996P2 arrives today. I was trying to get a head start with programing.

Yes, Some units use encryption and some don't. At the base where I live they use both P25 digital encryption and non encryption.

The USAF air bases in the UK use encrypted P25, and have done for quite a while - so it's world wide.

The NJ Air National Guard here at Atlantic City, NJ uses P.25 Phase 1. Half the time they are in the clear and the other half the transmissions are encrypted.

All I can find on RR's database in Michigan is what's shown below. Both are indicated that they're encrypted. I find it odd, that they also use analog un-encrpted all the time.

Here's the frequencies for Selfridge Air National Guard Base. Put them in your scanner and see what you can find if you haven't done so.

I have those. Many of them are no longer used. None are P25 digital that I'm aware of.

Always could program the 403-407 frequencies and scan them to see what you can come up with.

Search 162-174, 380-400 and 400-420 they may have gone there, or moved with the Fire to the MPSCS

I was driving by Grayling and heard gun range exercises on the MPSCS system in the clear.

Fort Leonard Wood, MO uses ENC on most of the military operations except for the hotel shuttle, maintenance and Range Control. Sometimes someone turns off ENC on accident and I get some action.
