Couple of things to watch

[riverradio68]

Good band openings this morning. FBI North Texas 167.2875 167 NAC Radio ID: 3144000 TGID: 65535 several hits all encrypted but well used. 2 bars from SE Fannin Co. It shows as WFalls Mobile and Houston so not sure which city I was hearing, probably WFalls. 167.3125 167 NAC (And I have it as Dallas North) Not as busy as the other but active. And several hits with good audio on the new Megahertz Tier 3 system. Dallas site 2 with a TGID of 1091 either professional Security or a Police Department.

Stuff is active, y'all with all that SDR stuff could be the next rising star in the Texas database!

SDR is a game changer for even novice users. Watch the band, find a signal even if weak, analyze. I haven’t gone as far as I want to go with a laptop mount and truck antenna for mobile use but I definitely pick up far more than I ever did with just a scanner.

I have two a RTL and a Nooelec and hate em both. TOO complicated for a East Texas good ole boy living in the land of conventional radio.

I can see where that can complicate things, but for the total system profiles we put into the database they are definitely a necessity these days. For conventional P25 or analog they aren’t necessary unless you are looking for the unknown, I.E. Federal…

You heard a repeater someplace and it wasn't from Wichita Falls.
I heard mobiles on 167.2875 simplex here a couple times several years ago and it's been dead since. Probably Dallas FO has a bunch of simplex channels and that is probably one of them.

Back when they went P25 I think they moved all the repeaters that belong to the Dallas FO out of the 167 MHz range to conform with the NTIA band plan. I think in Oklahoma many of them stayed there. Maybe it varies by field office.

Some of the stuff here Federal (Dallas County) Scanner Frequencies and Radio Frequency Reference I submitted over 20 years ago and are probably no good any longer. I don't think anybody cares about it now. The same is true with the wiki article Federal (TX) - The RadioReference Wiki.

I picked up what sounded like OTAR with the skip yesterday morning at 3 am, simultaneously, on 167.2625, 167.2875 and 167.3125. No P25 NAC was seen for them but it showed P25 on DSD Plus.

314#### - tells me Dallas FO coverage area- so not Houston

I've experienced this also, Audio is defiantly P25 but shows DCS codes. I believe system fusion can handle standard CTCSS and sounds like P25. I wonder if they're using a commercial version of that?

And OKC isn't outside of the realm of possibilities. I have a VERY OLD "D/FW Frequency List" Published by Ken Winters 5th. edition 1999 and I believe the final edition. I have some of that info programmed along with the newer stuff, some hits some don't.

If you are getting weird P25 sounding signals it could be intermod or images from other stuff in other parts of the band. If you are getting DCS or PL on a digtial sounding signal it is either the decoder falsing or intermod/mixing of P25 with an analog signal with DCS or PL.
Digital modes can't have DCS or PL. Thats what NAC, RAN, Color Codes, etc. are for.

I don't think there is a commercial version of YSF.

I remember the D/FW Frequency List. It had too much incorrect data. Not really worth the money.

The DCS could be coming down the line from a remote RX site, we've had that here in Boston a few times a year, usually when the remote site dips below 30deg and then hangs up a carrier from time-time
