Okfuskee and McIntosh County changes of modes?

[K5TGM]

I recently acquired a Uniden SDS-200 from Bearcat Warehouse and had them program those counties but also the one I live in. I am receiving what sounds like un-demodulated modes for the Okfuskee sheriff and car-to-car, as well as another on the McIntosh favorite file. I did another search of the database here on Radio Reference to affirm a change and as yet it has not been updated, Is anyone else in my area having the same issue for the Okfuskee County Sheriff and car-to-car? I have already contacted the seller about it and they do not know about a change to the modes used, but it sounds like possibly P25 or DMR yet I bought the DMR unlock and P25 comes included from the factory so?

Were you getting this early this morning? And does it seem to go away later in the day? If so, you're probably getting intermod from paging transmitters. VHF was open over NETX/SEOK this morning with some far stations coming in strong.

I am still getting this, and every once in a while, after the scanner stops on those channels, there is a CW ID after the ending of the buzzing. The buzzing has variations of tonal quality. I am now thinking they have switched to some form of encryption. This is a somewhat oddity as that county is small in size and population density is pretty sparse.
I am also a licensed Ham radio operator and currently have a 70cm beam in vertical polarization at 25 feet connected to the scanner, although with the antenna supplied with the scanner, I still receive these signals

If it sounds like static/loud white noise ending with an obnoxious BRRAAANNMPPPPPT kind of noise, it's probably encryption. VHF was open again last night/this morning with Broken Bow's NWS station booming in Kaufman, TX, so it could be from anywhere in the region. It drove me nuts at times in Houston, having that noise come in on an active local channel.

Certain times of year it can get hard to pinpoint where a station is, especially near border. If you can record the CWID to decode or even catch a tone or NAC to narrow down the search, you'll be able to figure out if it's your guy's encryption or just someone so impolite as to let their RF wander about aimlessly.

Decode the CW ID call sign and look it up on the FCC ULS website.

Post an MP3 of it on this thread and I'll let you know who it is.

If I hear the whole thing I will decode it myself and let you know, I was a novcie in 1977 and am bit rusty but I still copy cw a bit.
