Federal Emergency Frequencies

In the April issue of The Spectrum Monitor, I presented possible frequencies that would possibly be used, particularly in response to the COVID-19 pandemic.

Here are some potential monitoring targets for federal agency activity in areas in which federal agencies are supporting public health issues. First is the US Department of Health and Human Services (HHS). While their day-to-day activity probably does not have many two-way radios involved, they do have emergency response teams and those teams do have radios. Here are the frequencies allocated to HHS;

In addition to these frequencies, the National Telecommunications and Information Agency (NTIA) has allocated a number of VHF and UHF channels for federal agency interoperability. This allows different federal agencies some common radio channels where none had previously existed. Here are the current NTIA allocated Federal Interoperability frequencies, and these can be found in the NIFOG document I mentioned earlier:

Some areas have had National Guard units activated to provide mostly logistical support for areas heavily affected by the COVID-19 virus. In addition to their normal unit communications, they could be using the frequencies listed above, and you might consider the following frequencies, which are allocated to federal government itinerant use by any federal government agency:

National Guard and COVID-19 Operations

I have seen and heard some frequencies and radio systems that appear to be specially reserved for operations supporting response to the COVID-19 pandemic in various areas of the country. Unfortunately, many people seem to want to be given these frequencies instead of looking for them. Many of these channels, especially National Guard channels, are not well known and will have to be found by searching.

These frequencies will not necessarily involve medical calls or ambulances, but instead will be government agencies providing supplies or personnel to assist with food and equipment as needed.

Many National Guard units have access to statewide radio systems, either trunked or conventional.

For those who are interested, I thought I would post what I have found and add to it as new information comes in.

Navy Hospital Ships and COVID-19

The U.S. Navy has dispatched two hospital ships to New York City and Los Angeles to support medical efforts during the Coronavirus pandemic.


The USNS Mercy arrived in Los Angeles harbor on Friday, March 27th and the USNS Comfort departed Norfolk, VA on Saturday, March 28th for New York.


Originally no reports on what the USNS Comfort is using for radios after her arrival in NYC. However later posts indicate there is possibly activity on 385.1875 MHz, N401 that is related to the Comfort.

Here is a link to the thread on Radio Reference about the Comfort:

https://forums.radioreference.com/threads/usns-comfort.404034/


The USNS Mercy has been reported to be using an on-board UHF DMR radio system for their operations. The system is NOT using frequencies in the normal federal/military radio bands, but instead is using what are public safety allocations here in the United States in the UHF band. Here is a quick rundown of what is known so far:


DMR Motorola Capacity+

LCN 1 458.225, CC 1

LCN 2 458.325, CC 2

LCN 3 458.425, CC 3

LCN 4 458.525, CC 4

LCN 5 458.625, CC 5


Note the unusual use of the 453 MHz channels as inputs and 458 MHz channels as repeater outputs. This is often done in maritime applications of floating repeater systems.

The Passing of Uniden's Paul Opitz

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.

https://forums.radioreference.com/threads/sad-news-about-paul-opitz-upman.399210/

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;

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 P-25 DoD System Near Pittsburgh?

FBI Communications Compromised by Russian Agents

This story began circulating recently on the Internet - an interesting read:

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;

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.

Super Bowl 53 Wrap Up

Here are the listings of frequencies I logged during my two weeks of work in Atlanta at Super Bowl 53. While not all of the activity was directly related to the Super Bowl game, nearly everything in the area was affected by the event and the surrounding security operations. If I was able to confidently identify the users, I have provided that information:

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.
