One of the great monitoring locations I have encountered in my travels is O’Hare airport in Chicago (ORD). There is so much going on there, not just with air traffic and airlines, but the public safety and federal operations are always busy. One of the ongoing mysteries for me is what frequencies are being used by which federal agencies at ORD? In particular, the Transportation Security Administration (TSA). Since the TSA moved to their newer P-25 radios a few years ago, they seemed to be hard to catch at ORD.
Chicago usually has plenty of federal activity, and here is a listing of what I have caught over my last few visits:
162.0625 NC02 Customs and Border Protection @ ORD
