More Cities with New TSA Radios

Just passing through another set of airports this week and found the TSA at my home airport of Portland International (KPDX) is now starting to use the new Icom radios. I found them to be using 172.1500 MHz, 136.2 PL, but not always using the voice inversion option. They also continue to use 172.1500 MHz, P25 with various NACs depending on what checkpoint they are at.

However the personnel who were carrying the new radios also had the larger XTS digital radios as well. Not sure how they are using them as most TSA checkpoint staff have no radios at all.

TSA in Portland also continues to use the 172.9000 MHz, N001 repeater with encryption enabled. A few units are still in the clear, but I suspect the encrypted traffic are some specialized units, perhaps assigned to the ports.
