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

 

409.4875 MHz

411.2875 MHz

411.4875 MHz

411.5375 MHz

414.6125 MHz

414.637 MHz

415.7375 MHZ

418.4875 MHz

419.6875 MHz

The 406.7375/415.7375 frequency pair seems to be a repeater at most airports. The rest of the frequencies can be used as simplex channels.

 

Here are the cities and P-25 NACs that have been confirmed so far:

Airport                           P-25 NAC

AUS - Austin Bergstrom            N061

BOS - Boston Logan                N01C

BUR - Hollywood Burbank           N06A

COS - Colorado Springs            N076 

DAL - Dallas Love Field           N07C

DEN - Denver International        N016 

DFW - Dallas/Ft. Worth Int'l      N02A

EWR - Newark                      N03D

GEH - Spokane, WA                 N0E7

GJT - Grand Junction, CO          N243

HOU - Houston Hobby               N028

HPN - Westchester Co NY           N1CB

JFK - New York JFK                N02B

LAX - Los Angeles Intl            N031,N032

LGA - New York LaGuardia          N03A

MCO - Orlando Intl                N040

MDW - Chicago Midway              N070

ORD - Chicago O'Hare              N010 

PDX - Portland, OR

PHX - Phoenix Sky Harbor          N046

SAN - San Diego Intl              N0E0

SFO - San Francisco Intl          N049

TUS - Tucson Intl                 N0F0  

Here are additional 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.
