The other day on my break at work here in Portland, I noticed that the TSA 7/10 frequency was alive. It had a NAC of 001 of course and it was in encrypted. Later I noticed on IWN, there was an encrypted conversation going on that sounded like the same beat of voice in the encryption sounds as the TSA frequency. I later plugged the TSA frequency into my ASTRO Saber (only other radio with P25) and sure enough they were lining up. I didn't catch the talkgroup ID on IWN, but I think we have something here.
