On a quick visit in the Dallas area, I discovered some new P-25 frequencies active in the downtown Dallas area. 406.6625 MHz (repeater) and 415.6625 MHz (input to 406.6625) appear to be a 24/7 security operation. Local sources are indicating that this is most likely the Federal Reserve Bank, located at 2200 North Pearl Street, a stone's throw from where I was staying.

New TSA Freqs Found???
While waiting for my delayed departure from Chicago's O'Hare Airport, I found what appears to be several new P-25 conventional frequencies in use by the TSA (Transportation Security Administration). This seems to continue the trend of the TSA showing up on new frequencies where they might have interference issues with another nearby commercial airport. Previously I had only heard the nationwide frequencies of 172.15 and 172.9 in use at ORD, but here's what is being used now:
163.4750, P-25 - Repeater that seems to carry a lot of informal traffic regarding baggage screening and personel assignments. I did not find the input to this repeater.
165.8500, P-25 - TSA operations, appears to be the input to a repeater on 169.1625 MHz.
169.1625, P-25 - TSA Operations at ORD. This frequency is also used by the TSA at DFW Airport in Grapevine, Texas.
172.1500, P-25 - TSA Simplex operations at ORD. This remains as one of the normal, nationwide TSA channels that is still in use at ORD.
While searching these out, I also came across a P-25 repeater on 163.6250 MHz, most likely an Immigrations and Customs Enforcement (ICE) repeater at ORD.
