I’m posting this to more than one list in order to get coverage in neighboring states. I’m in NE KS and we’ve had a band opening in the past couple of days that has produced several unknown systems between 162-174 MHz. Can anyone identify these and tell me where they’re located? I’ll be happy to share any info with the group.
Thanks, Bob, WoNXN

What kind of traffic was on the P-25 freqs you listed? Did they sound like repeaters?

I'm afraid I didn't get a long enough sample to tell what was on the P25 channels. The 171 was almost certainly a repeater and probably an outlying FBI system. They've been building out in the 171 MHz. segment recently. The 163 may well be an input to an ICE system with an output of 163.625.

166.275R 127.3 PL is the police dept. of the Creek Nation. There is good tropospheric ducting from the Kansas City area into eastern OK today (Sat. 14 June).

Here are a coupla more mysteries.
172.2125 P25 encrypted, NAC 390
172.6875 P25 encrypted, NAC 293

Just thought I'd let you know that these are OKC freqs that are probably skipping into east OK or Kansas. 172.2125 (390 NAC) is an encrypted repeater, possibly for interoperability. 172.6875 (293 NAC) is the VA Medical Center security.
