I saw your post (before it got deleted) asking if it was from Camp Atterbury. I can (barely) receive the Camp Atterbury 380 MHz system here in Greenwood but don't hear anything on 173.5875.

Thank you. There is some enhancement this morning. I'm receiving A63 1.1 very well this morning. For context I'm also receiving VASTARS site 2.13 🤦‍♂️🤷‍♂️. Sometimes being able to receive for hundreds of miles is a curse. DSD+ is right there on that fine line of attempting to decode this 966 system.

Oh, here's a revelation, I just lost TV signal from Fort Wayne, and there was an abrupt stop to seeing the 966 system on SDR#.

Disregard this. That was a fat-fingers operator error. Apparently I bumped the VFO.

My scanner did start receiving 966, that's how I found my error. In my experience, typically DSD+ will decode a site long before a scanner will be able to receive it.

TG 1010 appears to be the most active TG I have seen. RID: 32346 seems to be pretty common, possibly a dispatcher.

That RID looks familiar, or similar to another I've seen. I want to say it may have been IU Health or LifeLine dispatch.

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.

Do you have any large National Guard facilities in the area? Several of them have their own trunked systems.

There is a National Guard armory in nearly every county. Some (maybe all) have a tower with an antenna, but I haven't found one with their own radio system yet. There isn't enough activity around the individual armories for that. Indiana's National Guard also has access to the statewide P25 SAFE-T public safety radio system.

Indiana has a National Guard training base, Camp Atterbury, and it has two 380Mhz sites on its own P25 system.

How long has it been on the air and is it still there?

I found it a week ago. I'm not currently seeing it.

It might be a field deployed national guard (or other branch) system.
Several years ago this one showed up at Fort Sill, OK for a couple weeks and then disappeared.

I agree! It may be a SOW for Camp Atterbury, since 5,000 Afghan refugees are going to be housed there. I posed that exact question in the Indiana forum, but the forums admins deleted the thread because I posted about this unknown system here, in the Federal forum. Apparently you can only post in one forum about trying to find unknown systems. I made the mistake of posting in the Federal forum first. (See comment #19).

One potential theory for temporary radio systems at military bases could be construction contractors, or military units tasked with establishing/building bases for the anticipation of standing-up the location. If a contractor or unit is only tasked with standing-up and tearing-down locations it would be easier for them to bring a SOW with them, versus reprogramming comms for every location they go to.

They would have to reporgram anyway. It's not very likely that there would be a set of SOW frequencies that can be used anywhere in the country. If there was then they wouldn't be using commonly used frequencies like 173.5875.

Yea, that is probably true. That is a common air base fire/crash frequency. Camp Atterbury does have a runway and fire dept. News reports said the Afghan refugees were being flown into Indianapolis International airport. I'm not sure if they're being buses to Atterbury, or using a connecting flight to Atterbury. It seems like it would be a lot more efficient and easier to fly into Atterbury. If they're being flown into Atterbury, and with housing 5,000 people on base for an unknown amount of time, that may warrant standing up a standalone Fire Dept radio system.

@usswood Are you able to check the Terre Haute area for this system? It could possible be IN ANG @ Terre Haute.

 

[usswood]

Not hearing anything on the west or east side of Terre Haute

Guys, what's the likelihood that this system could be Scott AFB in St Clair county, Illinois?

Scott Air Force Base Trunking System, Mascoutah, Illinois

The freq is listed as being used on the base as an EMS Disp channel, their TGs on their UHF P25 system are similar numbered, and I found a comment from 2014 asking if they've switch from their VHF system to a UHF system.

On 966 I've received TGs 1001, 1003, 1005, 1007-1010. Their UHF TGs have been documented to start at 1013 and go up from there.

Additional Info: I have a good radio path that direction. I receive the Danville,IL (151.055) and Vermillion county, IL (154.755) VHF DMR systems everyday.


I would ask the in IL Forum, but it would just be deleted. 🙄

@Starcom21 I noticed you're around STL. Have you monitored 173.5875Mhz for this system, possibly coming out of Scott AFB?

 

[Starcom21]

I'll check it out when I can
