TSA Frequencies





TSA Nationwide Frequency Updates
 
NOTE: The TSA is planning on moving their radio communication systems from VHF to UHF federal frequencies beginning in 2021. Updates will be posted here as they become available.

NOTE: The TSA is currently in an upgrade/replacement program for their radio systems. Frequencies may or may not change, but P-25 NACs will change and encryption will likely be more prevalent. Frequency and NAC changes will be highlighted in RED. New UHF frequency information will be in BLUE.

When searching for TSA activity, always assume that the TSA at your local airports will have some of these four frequencies in use:
166.4625 MHz
169.3000 MHz
172.1500 MHz
172.9000 MHz

In addition, here are some of the "secondary" frequencies that have been identified as TSA at various airports:
163.3125 MHz
163.6750 MHz
163.7750 MHz
163.8500 MHz
166.2875 MHz
166.5875 MHz
166.7875 MHz
168.0875 MHz
168.8375 MHz
168.9625 MHz
169.1625 MHz

169.3875 MHz
171.7625 MHz
173.0875 MHz 
 
And now the TSA is in the process of moving over to new, P-25 UHF frequencies. These frequencies can be used with different P-25 NACs. Here is a list of the frequencies found active so far:
406.7375 MHz
 
406.9250 MHz
 
407.6500 MHz 
 
407.7000 MHz
 
409.4875 MHz

411.2875 MHz

411.3375 MHz 

411.4375 MHz

411.4875 MHz

411.5375 MHz

413.9500 MHz

414.6125 MHz

414.6375 MHz 

414.6750 MHz

414.9500 MHz

415.7375 MHZ
 
416.7000 MHz

418.4875 MHz

419.6875 MHz

The 406.7375/415.7375 frequency pair seems to be a repeater at most airports, but recently 407.7000/416.7000 repeaters have been confirmed. The rest of the channels so far appear to be simplex only.
 
Here are the cities and P-25 NACs that have been confirmed so far:

Here are additional VHF channels that have been identified at various airports as being TSA operations. If the channel is designated with a CTCSS tone, it is an analog channel using voice-inversion scrambling. P-25 channels are noted with the appropriate NAC.

The analog channels are usually the security checkpoint screeners using Icom F-50v radios. The additional P-25 channels are usually the operators of the full-body scanners communicating with the checkpoints. The operators of these devices are located in a separate area away from the security checkpoints.

It has been noted that with the deployment of the new BK P-25 radios across the country, the use of the analog Icom radios has been discontinued. 

It should also be noted that the body scanners are now more autonomous and do not require operators relaying information over the radios, so many of these channels have now gone silent.
