I was working last night around 10th and Meridian last night in OKC and had a pretty good lookout from on top a hill. Searched around the 162 - 170 and 406 - 420 ranges and started getting hits. Didn't realize until just now where they were and identified Altus AFB security on 163.4125 (192.8 PL). Not bad. Also caught 154.785 (173.8 PL), 155.61 (203.5 PL), 410.825 (173.8 PL), and 164.100 but wasn't able to ID them via statewide search (RR, OK-TX-KS). Lots of APCO-25 in the UHF federal band, but I can't listen to digital yet. Gilligan
