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.

If you have any frequencies or information on COVID-19 response frequencies, feel free to send them to me on Twitter (@TheFedFiles) or email

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:

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.
