Word began spreading last night about the death of Paul Opitz, otherwise known as "UPMan" on the scanner forums on Radio Reference.
Paul was the product manager for radio scanners at the Uniden Corporation in the U.S. He was instrumental in the design and development of all the recent models of radio scanners made and sold by Uniden.

Paul discovered he had cancer very suddenly in 2017 and decided to blog about it. It shows how determined he was to fight and provided some interesting insight to the man that many radio hobbyists knew, but had never met;

THE FED FILES - Welcome to The Fed Files blog! This blog was originally built to support the "Fed Files" column in Monitoring Times magazine. Although the Fed Files, as well as Monitoring Times, ended with the December 2013 issue, this blog continues and is associated with the new federal monitoring column, Federal Wavelengths, in The Spectrum Monitor magazine.

January 2020 TSM Corrections
Well, I somehow managed to fat-finger some frequencies in the January 2020 edition of Federal Wavelengths and wanted to post some corrections.
In my January column I spoke about where to look for federal radio traffic. Here are the ranges as I intended to list them:
Most of the active federal radio systems near you are going to be in two distinct bands of radio frequencies. The federal VHF Hi-band runs from 162.0 MHz to 174.0 MHz, with the channels being assigned in 12.5 kHz steps. The federal UHF band runs from 406.0 MHz to 420.0 MHz, also in 12.5 kHz steps. There are some additional ranges of frequencies that are sometimes used by federal and military operations that might be active in your area. The VHF lo-band from 30 MHz to 50 MHz is often used by military aircraft and ground units in the FM analog mode. The ranges of 138.0 MHz through 144.0 MHz and 148.0 MHz through 150.875 MHz are often used by military land mobile and aircraft operations. They can be AM (for aircraft) or FM (for land mobile) mode and may be digital as well. There is a small piece of radio spectrum above the federal UHF band that runs from 400.0 MHz to 406.0 MHz, that is normally assigned to radio astronomy use, but there are exceptions for military and federal use. There have been several examples of federal operations being heard in this range of frequencies, but it’s rare."

Another 380 MHz Trunked System and Garage Doors
Another story has emerged about people having trouble with their garage door remote controls likely due to interference from a government 380 MHz trunked radio system:
https://www.fauquiernow.com/fauquier_news/article/fauquier-feds-admit-radios-interfere-with-garage-door-openers-11-5-2019
These systems have been blamed in other areas for causing issues, but since the garage door openers are FCC Part 15 devices, they have to accept any interference from licensed users. The door opener remotes are often built with poor selectivity and get de-sensed from the legitimate radio systems nearby.

VHF Marine Channel Number Changes
The US Coast Guard has a nice chart of the numbering changes on some of the VHF marine radio channels used in the United States. Here is a link to the chart:
https://www.navcen.uscg.gov/?pageName=mtvhf
So why the changes? Here's an explanation from the Coast Guard:
Note that the four digit channel number beginning with the digits "10" indicates simplex use of the ship station transmit side of what had been an international duplex channel. These new channel numbers, now recognized internationally, were previously designated in the US by the two digit channel number ending with the letter "A". That is, the international channel 1005 has been designated in the US by channel 05A, and the US Coast Guard channel 1022 has been designated in the US as channel 22A.

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;

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.

Many of the Super Bowl related federal operations were heard
mostly unencrypted up until the day of the game, then most of the transmissions
were fully encrypted.

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
System Name : SOUTHEASTERN US VA MEDICAL CENTERS
WACN : BEE00
Tower Number (Decimal): 1-41
Tower Number (Hex) : T0129
Tower Description : 1-41 ATLANTA
Control Capabilities : Data,Voice,Registration
Flavor : Phase 2
