ELMR 14C Sites in Barstow CA

On a recent drive between Las Vegas and Burbank, I ran across two ELMR 14C sites in Barstow, CA supporting the Marine Corps Logistics Center there; https://www.mclbbarstow.marines.mil

The Radio Reference database has never shown any sites for Barstow, so these may be new.

Also, the 14C system has been undergoing upgrades to Phase II and some site number changes, so some of the data shown on Radio Reference is out of date.

Here are the PRO96COM logs - note that the two sites only show each other as neighbors. Both sites were showing a P-25 NAC of N14C;

Providence, RI

Time for an update to the Fed Files blog!

I recently spent a few days in the downtown Providence area and had some interesting federal radio activity. Here are  few things I heard:

162.6125, N293  - VA Providence, repeater out. 

162.7000, N293 - Input to US Marshals Service 170.7500

163.0875, DCS 351 - VA Maintenance repeater out.

164.7000, DCS 023 - Automated alarm notifications - VA Telcom repeater out.

166.5000, DCS 351 - Input to VA Maintenance repeater.

170.7500, N293 - US Marshals Service Federal Courthouse

171.2375, N293 - US Coast Guard NET 127, Warwick, RI 

172.1500, N0D3 - TSA at PVD airport

173.2250, NXDN RAN 30, probably not federal, radio ID of 60991, talk group 20005, all ENC

406.1375, CC1 - DMR US Postal Service Capacity +

407.3375, CC1 - DMR US Postal Service Capacity +

408.2000, N201 - Federal Protective Service

US Miltary P25 Low Band Report

I have reported several sources indicating that they have heard some P-25 digital modes in to 30 - 88 MHz VHF low band that were assumed to be military. Some were with confirmed P-25 Network Access Codes (NAC), but I have recently heard a report of actual military activity using P25 digital.

From somewhere in Wisconsin:

40.4000 MHz, P25 NAC F7E - Military aircraft (helicopters) in the clear, base side encrypted

Some have asked how this can be, as none of the major equipment manufacturers make VHF low-band P-25 radios, at least not for civilian use. 

The major players in the military communications market (Harris, Thales, Motorola) all offer wide band, multi-mode radios that can be used in nearly any mode on any frequency. P-25 is an optional mode for these radios. 

It's still not known for sure if this is an intentional move to use P25 in the VHF low band, or just accidental programming of a particular channel. 

More DEA VHF Transition

Some new VHF frequencies likely being used by the DEA have been heard active in the San Francisco Bay Area in California. Here are the confirmed frequencies:

172.2125, N156
173.1625, N156
173.4750, N156 
173.9250, N156

The old UHF DEA frequencies have been pretty quiet in the Bay Area for some time, and one source even mentioned seeing the old DEA UHF repeaters being removed from service.

New Federal UHF Trunked System in Austin, TX

A new UHF P25 trunked system in the UHF band has been reported in the Austin, Texas area. Discussions on Radio Reference can be followed here:

https://forums.radioreference.com/threads/unknown-networked-federal-p25-system-in-the-austin-area.386659/#post-3105851

The system has been reporting this information so far:

WACN 0000A 
SysID 00A 
Site 005-005
Control channels   407.075 406.775 
neighboring site     001-001 408.625 
neighboring site     003-003 406.775

Unfortunately, the system ID of 00A is a "default" system ID that many Harris trunked systems start out with, and many do not change.

New Federal Bay Area VHF Trunking?

Reports have been posted on Radio Reference about a new VHF trunking control channel being heard in the San Francisco Bay area of Northern California. Best guesses are that the control channel is coming from Mt. Tamalpais, a popular radio repeater site. 

Here is the system information so far:

173.7875 MHz
P-25 Phase 2
System ID: 4D5
RFSS: 003
Site ID: 067
WACN: BEE00

The system is now in their database:

https://www.radioreference.com/apps/db/?sid=10459 

Since no traffic or talk groups have yet been seen active,  the system may or may not be actually using P-25 Phase 2 voice.  

Speculation abounds as to who this system is being built for. One poster mentioned he had knowledge of a "new federal system for Bay area coverage", but no speculation on agency or agencies.

Super Bowl 53 Updates

Once again I am at Super Bowl LIII in Atlanta, Georgia. I will post some limited updates on federal activity here, but nothing on active operations during the events.

I can confirm a few things that haven't been updated in a while. For some time there was a UHF trunked system in the Atlanta area that was used and manged by the Federal Protective Service, and had leased space used by the various military bases around Atlanta. This system is  no longer on the air, but FPS is using 410.8000 MHz, N201 for conventional operations. I've also heard the FPS on  409.2625 MHz, N201 and 413.9500 MHz, N210.The military bases have moved over to a 380 MHz trunked system,  https://www.radioreference.com/apps/db/?sid=7895

I'm hearing the Federal Interoperability repeater on 170.4750, N653 is in operation.

168.8375, N293, CBP AIR 1, was busy with traffic about checking a live video downlink.

Tonight I found a multi-site P25 Phase II UHF trunked system. It shares the same system ID as the Department of Veterans Affairs system in the Orlando and Miami areas. Might be networked with Florida:

System ID             : 3CD
