Oklahoma FBI Freqs

[Gilligan]

I'm starting to find quite a few FBI repeaters around Oklahoma. I'd like some of you from different parts of the state to take a little time and search the 167-168 MHz range or scan these particular freqs. I'd like to find out where the signals are the strongest so it can be determined which repeaters correspond to which offices. Here's what I've found so far:

(All use a tone of 167.9 PL for clear voice; using a tone will avoid hearing encryption)

170.950 - OKC office
168.275 - OKC (heavy use, encrypted)
167.2625 - Enid office (need to confirm)
167.4375 - Ardmore office

Now here are the ones that I'm looking for signal strength reports on:
162.7125
162.7375
167.2375 - repeater
167.3125 - repeater
167.5125
167.6625 - repeater?
168.350 - repeater
170.625 - repeater
173.625

If you are able to search 167-168 MHz with 167.9 PL tone, that is where most of these repeaters are showing up (in 12.5 KHz increments). Also, please realize that hearing clear-voice communications on these frequencies is kind of rare. You won't hear a lot but you might just keep them in your scan or search list. Even if you can't remember what you actually hear, what will help to figure this out is finding out what areas these repeaters are full-quieting in. I'm hearing towers that are about 100 miles away, and clear enough to make out what they say (which helps in identifying them).

One more thing, I noted that the 168.275 repeater was possibly some kind of link to the FBI in Arkansas. After careful listening and some common radio sense, I've now determined that it was skip from Arkansas into the OKC 168.275 repeater. They probably shared the same input and so the OKC repeater was hearing it from Arkansas.

Elk City's is 167.68750 digital, and it's listed in the db.

167.3125 was heard while driving through on 75 just over a week ago in SE part of OK. Signal strength was about half. As I got closer to the Lake Eufala, it seemed to be distant. Repeater seemed to be closer to the TX state line.

According to the FBI region map, it appears that this repeater on 167.3125 could possibly be for the Durant FBI office.

I also found 167.6125 to be in use in eastern OK as you approach Missouri.

I am assuming that this would be near I-44 northeast of Tulsa.

Heard simplex ops on 163.4375 (167.9 PL) yesterday.

I've been monitoring 167 - 169Mhz and all I'm hearing is railroad dispatchers in the Tulsa area.

 

[Gilligan]

You might be catching images cause railroads are 160-161. I don't mess with 168 much cause it's mostly interference. In fact, all the FBI action I'm catching is between 167.2125 and 167.7875. Here's my basic band scan:

162.7125 - 162.9875 (25 KHz steps)
163.0125 - 163.9875 (25 KHz steps)
164.0250 - 164.9750 (25 KHz steps)
167.2125 - 167.7875 (25 KHz steps)
170.0250 - 170.9750 (25 KHz steps)

For the 163 range, I would scan 163.0125, 163.0375, 163.0625, skipping 163.025, 163.050...
Most of my action is on these 12.5 KHz splinter channels.

I went to Stillwater over the weekend and found their local FBI office within a few hours. They have a repeater on 170.625 and they call it A1.

Gilligan, is digital? Hmmm I might have to plug it in and listen. Thanks for the heads up.

I don't know how much they use encrypted because I only listen w/ the 167.9 PL tone enabled. Otherwise, my scanner would stop on a lot of interference and noise that would come through. Listening w/ the tone prevents any encrypted/digital comms from coming through (thankfully). The only thing that listening to encrypted comms is good for is determining the amount of use a freq has for the agency. For example, I hardly ever hear anything on 168.275 in OKC. But if I listen w/o a tone, there's a tone of encrypted stuff going out on that repeater. So I would venture a guess and say that since 170.950 is apparently their dispatcher, 168.275 is probably their surveillance repeater. You guys really should listen to those FBI ranges and see what's there -- probably more than you would think is in the clear.

Did you say the TX your heard here in Stillwater was 170.625 with a PL 167.9 or was it 170.95 PL 167.9 I have had 170.625 in my main scan set up since you first said you heard traffic on it and have not heard a thing???

I'm 100% sure that it was 170.625 (167.9 PL). It was definately local and not skip from OKC.

 

[peterjmag]

Okay thanks, I'll keep a listen.

When I'm in the Ponca City area I hear 170.95 (encrypted) at local strength in the mobile, so they must have a repeater up in north central OK.

106 file for okc

hello looking for a okc file if someone would be willing to share this that would be great i have a 106 ok question do i need the cable and win500 to program this file thanks for any help....

Thanks for the info, Bob. I heard some comms in the clear lately on our local 170.950 & 167.2375 here in OKC.

Does anyone have any tower information about these repeaters? Like would anyone happen to know where the 170.950 and 167.2375 repeaters are located? Heard that the FBI had repeaters on a shared tower or anything?

Yes do put that info out here in the WIDE OPEN. The bad guys may need to know how to disrupt "The Mans" comm some day. :|

 

[ecps92]

There's more of a change for some ID10T to interfere with the Local Public Safety than the Federal Radio systems..

I heard a dispatcher talking to a field unit transporting to Grady County yesterday. It was simultaneously on three repeaters, all with 167.9 PL: 167.3875 (newly discovered repeater), 170.950, and 167.2375. From my location in west OKC, the 167.3875 repeater was slightly more distant (or weak) than the other two, which could mean that it is not an OKC repeater but just has the same input as the others.

 

[Secret_Squirrel]

Also, another thing you guys might want to consider is the fact that not everyone operating in the "federal" assigned radio spectrum is actually "the feds". Doesn't make it right, but it does explain why some of the VHF communications are "in the clear" when one would normally think they should be encrypted.
