Unknown P-25 UHF System

I'm down in the Norcross, GA area with the PGA Championship Golf TV coverage this week, and started picking up a UHF trunked system I have no info on.

I'm getting a control channel on 406.7750 MHz, P25 System ID of 3B9, WACN BEE00, Site 103. It shows connected to Site 101 (406.1125), Site 102 (408.8375) and Site 104 (408.8375). I'm thinking there might be some military connection as the tables show a 380 MHz band available.

It's not coming in super strong up here northeast of Atlanta, but it is consistent. None of these frequencies or system information shows up in Internet searches or Radio Reference.

My first thought was that they could be upgrading the Federal Protective Service trunked system in Atlanta to P-25. It is also a 4 site UHF system. But, when I drove up from the airport last week I don't recall coming across these trunked sites in my initial scan/search of the federal bands.

Anyone want to take a guess at who or what this system is and where it's located?

Border Activity

In addition to DHS Border Patrol traffic, some listeners have reported activity that may be related to National Guard support of border enforcement.

From Eagle Pass, Texas comes a report of 391.0500 MHz, P25 with a NAC of N500. The report says the traffic is encrypted full time and not from Laughlin AFB.

Reports also mention some unknown type digital traffic in the 380-400 MHz bands that are not P-25, and rumored to be coming from Piedras Negras, Mexico.

An alert reader pointed out that there is a wide-area TETRAPOL trunked system used by the Mexican Federal Police Forces, which may account for the unknown type digital traffic in the 390-400 MHz band.

Upcoming POTUS Bus Tour

An upcoming bus tour of the Midwest US has been announced by the White House. President Obama will embark on a three-day tour from August 15 through 17. The administration said Wednesday that the trip had long been planned, but wouldn’t outline an itinerary:

There is a line in the story that mentions that the "Secret Service purchased two armored buses for its fleet earlier this year". This could be an interesting opportunity for some listeners along the bus tour route to see what they have incorporated in these buses for communications.

Apparently the buses mentioned in the above article were purchased from this company:

They list several political tours as well as some federal government agencies as clients.

NOT the Presidential Tour bus, but an interesting possibility:


Well, not much reported from monitoring the POTUS bus tour of the midwest, but did get a real picture:
