TSA Busy!

With the security level at US airports now at ORANGE, the TSA has been extremely busy with the added security checks. If you live near an airport with commercial air service, try these frequencies and see what's going on:

166.4625 MHz - DHS Common
169.3000 MHz - TSA input to 172.9000 repeater
172.1500 MHz - TSA Simplex
172.9000 MHz - TSA Repeater or Simplex

All TSA communications are using P-25 digital mode. This channel plan should be used nationwide, with the exception of the DFW Airport in Grapevine, Texas. They are using a repeater on 169.1625 MHz, input of 165.0750 MHz. So far no encryption has been noted on TSA frequencies.
