Federal Trunked System 3CD

Some recent discoveries of new control channels in the federal UHF bands have indicated that these trunked systems are part of a larger trunked system core, using the system ID of "3CD".

This is a single system core that is managed by Motorola Federal Solutions. They call it the Managed Zone Core:

https://www.motorolasolutions.com/content/dam/msi/docs/business/solutions/industry_solutions/us_federal_government/_static_files/us_fed_managed_zone_core.pdf

Motorola drops trunked sites as needed and then leases sites on this core to various federal locations or facilities that don't have the budget to build a system from the ground up. 

So far, a majority of the sites seem to be at Department of Veterans Affairs medical centers and hospitals. But a number of sites in multiple states are utilized by the Center for Disease Control (CDC).

While all these sites and agencies share the system core controller, they are not interconnected with each other. Each operates like it was a standalone trunked system. I do think some of the VA sites in Florida may be networked to each other, as I did hear some testing early on that was identifying various sites for test counts.

There are probably more federal facilities that may end up using this system core, so keep an ear out for P25 control channels in your area that have the system ID of 3CD!

 

RC-26 Aircraft Use In Protests Investigated

 

Articles in the Air Force Times indicates there was an investigation into the use of  Air National Guard RC-26 surveillance aircraft for airborne observations of the protests in various cities around the country.

 https://www.airforcetimes.com/news/2020/06/18/ig-investigating-air-national-guards-use-of-recon-planes-to-monitor-protests/

 https://www.airforcetimes.com/news/your-air-force/2020/08/21/ig-air-guard-intel-planes-surveilled-seven-george-floyd-protests-without-proper-authorization/

 The bottom line appears to be that the requests for use of the aircraft did not go through the proper authorization needed for this type of operation. The RC-26 aircraft are not considered "intelligence" gathering platforms by the National Guard Bureau. 

163.4625 Mystery

 OK, blog readers, here's another federal frequency mystery for you...

163.4625 MHz, NAC 001, radio ID of 1, talk group of 1.

Heard encrypted communications in the Seattle area recently. A check of my logs have shown that it mostly appears to have been allocated at various military bases across the country. 

 I have logged it with various NAC values at some of the Super Bowl games I've been working. 

The NTIA allocations seem to indicate military or Department of Energy allocations.

 Any guesses?

 

 

West Palm Beach Monitoring

 

Since Donald Trump became President, there has been much speculation about frequencies in use at Mar-A- Lago, Trump’s compound near West Palm Beach, Florida. Many local listeners have claimed the Secret Service wasn’t using their usual VHF or UHF radio frequencies as none of those had been heard active when the President was on location. However, I had an associate who happened to be in West Palm Beach and just a short distance from the Trump compound. He managed to log quite a few known Secret Service and White House Communications Agency (WHCA) channels active prior to a POTUS arrival, so I think the rumors of a new, super-secret, GHz band radio system in use there may be premature.

Ft. Lauderdale Frederal Frequencies

As I was in the Miami area for over two weeks for the Super Bowl, I spent a fair amount of my down time at my hotel, which was located in Fort Lauderdale. Even though I didn’t think I would catch much Super Bowl related communications from there, I figured it would give me a chance to check out routine federal activity in the Broward County area.

I set up a couple of antennas on my hotel room balcony. Many people who spotted my antenna setup on my Twitter posts wondered what kind of antennas they were and how they worked. I ended up doing a lot of Coast Guard and marine traffic monitoring as I had a front row seat at the entrance to Port Everglades.

Here are the active frequencies I logged from my hotel room monitoring setup:

March ARB Trunked System

There have been some changes to the March Air Reserve Base VHF P-25 trunked radio system in Riverside, California. These changes might not be obvious to listeners in the area.

The system is still P25 Phase 1, but it has had a change in some of the frequencies and now is part of the larger US Air Force 3D6 trunked system. 

Here are the specifics of the current system:

System ID : 3D6
System Name : March ARB
WACN : BEE00
Tower Number (Decimal): 1-13
Tower Number (Hex) : T010D
Tower Description : Single Site
Flavor : Phase 1

138.61250
138.63750
138.68750
138.71250

The system information on March ARB on the Radio Reference site has not been updated to reflect these changes, but here is some information on the USAF 3D6 trunked system: https://www.radioreference.com/apps/db/?sid=7769
 

FCI Sheridan TRS

I had a chance to stop by the Federal Correctional Institution in Sheridan, OR this week, so I could check on what type of radio system is in use there. It turns out to be the same system I found last time I was there 6 or 7 years ago.

Even with some federal prison facilities now upgrading or replacing systems with P-25 digital trunked systems, many are still using the Motorola type II trunking. In this case, they are still type II with digital voice. 

Here are the goods on their current trunked system:
