Some tips for finding the TSA channels. 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
Here are additional channels that have been identified 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, although new versions of these machines no longer require operators aside from the agents at the machines.
