TSA Frequency Updates



TSA Nationwide Frequency Updates

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.

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:
166.2875 MHz
166.5875 MHz
166.7875 MHz
168.0875 MHz
168.8375 MHz
168.9625 MHz
169.1625 MHz

169.3875 MHz
173.0875 MHz

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.
