Over the last year, there has been some anticipation over the move of the Transportation Security Administration to new radios. They had been seeking new UHF radios to replace their current VHF BK radios used in most airports around the United States.
Today, I received word of some activity on a federal UHF frequency in the Boston, MA area that is likely a new TSA UHF repeater system at Logan Airport.
The active frequency was 406.7375 MHz, NAC was N01C. Radio IDs were in the 839xxx range. Clear testing was heard from locations around the airport terminals. Encryption was also noted.
The frequency is interesting as I have no reports on that frequency use before. It is listed in the NTIA documents as being paired with 415.7375 MHz for repeater use.
More on this as I receive additional reports.
UPDATE 11/23/21 - Colorado Springs, CO is now using 406.7375/415.7375 repeater with a NAC of N076.
And thanks to all my anonymous sources!
