Unknown BEE00.966 173Mhz P25

[west-pac]

System: BEE00.966
NAC: 960
Freq: 173.587.8-ish
Location received: East Central Indiana.

Anyone familiar with this system or frequency? For about an hour this site was just below the threshold of being able to be decoded by SDR#/DSD+. At the same time I was seeing this site, I was listening to Chicago PD UHF. Chicago PD faded away first, then 20 minutes or so later this site faded a bit as well. This system/site may be in the Chicago-land area. Also, FWIW, all day Saturday I was seeing WISCOM 139Mhz sites on SDR#, but didn't have enough signal to decode them; similar to how this 173Mhz site is acting. Unfortunately, my typical DX range is Wisconsin, to Missouri, to western VA, to Detroit, MI. I presume since I've been receiving to the northwest for the past 18 hours that this system will be northwest of me as well.

Found this old thread that lists 173.5875 as a known Air Force base freq in Wisconsin, for either security/police or Fire/Crash.

SE Wisconsin federal/military wildcards

So, I'm going to try something new. I've recently found renewed interest in federal/military scanning. I've been submitting a lot of new channels to the Wisconsin and Illinois federal databases, but I'm always working through wildcards that I haven't yet identified. Instead of posting a new...

Does Dsd list any neighbor sites?

 

[RaleighGuy]

There are over 200 commercial entities around the US that are licensed on that freq, might not be federal.

Does Dsd list any neighbor sites?

I didn't have enough signal for a long enough length of time for DSD+ to decode the site and put the information in the Event window. The information I was able to gather came from the DSD+ main window as it scrolled occasionally. Eventually I was able to see a site number of 1.1, but I never saw any adjacent sites.

I would re-check your FCC search parameters.

That is 100% an NTIA assignment and the only Non Federal that show in the FCC is ORBCOMM License Corp for mobile satellites in
the range [not a specific freq assignment] of 137-401

You are correct. sorry

Thanks to @Tim in Wisconsin, he was able to determine that this P25 system is not in Milwaukee at MKE. At the same time I was seeing this CC signal again, he was not hearing a CC signal, yet hearing P25E conventional from MKE.

The next stop on the 'Where am I located' Tour will be asking for someone around Youngstown, Ohio to given a look/listen. 😂

Good luck. It took over 4 years for somebody to find this one.

I'mma find it!

It would be much easier if there was a 'Where am I located?' forum that users could look at and then check their local airwaves for. The admins tend to get sh*tty when you post in multiple forums, but this system is Federal DX from the midwest, so my question may end up in 9 forums (Federal, DX, Indiana, Michigan, Wisconsin, Illinois, Kentucky, Ohio, and DSD+) just to find the right person that is local to the system and can identify it. 🤷‍♂️ There is no reason for it to take 4 years to identify a signal if you communicate with the right groups of users in the forums.

It took nearly six years for someone to nail down a system after I first found it.

Does anyone know if they operate on the 380mhz system. I drive by the base on my way back and forth to work five days a week and have always been kind of curious if base FD & PD ops were able to be monitored, since I can't locate the info in any of the data bases. Thanks

I finally was able to get DSD+ to decode this site and put the info in the Event window, although it didn't give me much more information. There are not any neighbors, or even an ACC/SCC. I haven't seen any activity, nor traffic either

In the DSD channel activity window it shows: Ch 4-0 173.5875 CC. In the DSD main window there are lines showing "IDEN_UP_VU ID=0 Base=173.4625 Offset=-10 Spacing=6.25 BW=12.5"

Are these other ID=(x) numbers the other frequencies on the site? If so, then the frequencies on the site would be ID=0 173.4625, ID=1 173.5375, ID=2 173.4375, ID=3 173.4875, ID=4 173.5875.


Current reception conditions this morning:
I've had DSD+ parked on 173.5875 since Sunday and it hadn't decoded this site until about 02:30 EDT this morning (Tuesday). It's been a solid decode for the past 90 minutes.

Shortly after having enough signal to decode this site I started hearing Chicago PD 460.1750Mhz, which has been parked on one of my scanners since Sunday.

Shortly after receiving Chicago PD I started receiving WISCOM Site 1.15 139.3125Mhz on another one of my scanners.

I'm also receiving the Toledo, OH P25 system: 1CF site 3 on 770Mhz.

Apparently band conditions are currently enhanced, which leads me to believe this 173.5875 P25 system is at least 100+ miles away from my location.

I just received a "Status 1024; Tgt=7065250 Src=200458" on this 966 P25 system. Is anyone familiar with air base RIDs in the 200458 range?

Grissom ARB, in Indiana, has RIDs in the 206xxx range.

Edit: just received a Registration and Affiliation of RID: 19012 on TG: 1010.

 

[west-pac]

Seen TG:1010 RID:32346 173.4375 CH 2

Edit: it did not indicate it was an encrypted TG either.

 

[slicerwizard]

Are these other ID=(x) numbers the other frequencies on the site?

No, they're bandplans and some/most are likely unused.

 

[west-pac]

No, they're bandplans and some/most are likely unused.

So is it a coincidence that the frequency labeled as ID=2 in the DSD main window showed up as a voice channel labeled Ch 2 in the activity window?

At this time I am not receiving a signal on 173.5875. I will leave DSDPlus running on the freq overnight as when my rf rich environment goes to bed, I pull in signals from farther away.

 

[west-pac]

Admins/moderators, if you're not going to allow me to reach out to users in any state forums regarding this system then delete this thread in the Federal forum. More users look at their individual state forums, versus this Federal forum. Radio waves don't stop at state lines and international borders. If you live near state borders, or are able to receive signals from several states via Tropo, a particular radio system/site could be in any state within a radius around your location. Thanks for making things more difficult and time consuming.
