I've heard A-12 in the past, and I think A-11 as well, which is why I kept them unlocked and was able to catch the testing. A-12 was used at a concert, either on the lawn at the Cardinals stadium, or at the baseball field, I can't recall exactly which.
I personally label them Event 1 and Event 2.
A-10 has been used for training. It's kind of funny to hear "pursuits" going around in circles on the track at Glendale's regional training center, which is laid out like city streets, and given the same street names as those in the same alignment outside the training center. I also heard recently a female going 10-7 from city hall on A-10, perhaps having provided security for a city council meeting?
I'm not sure if I've heard A-13 in use at the Coyotes arena. A-14 has been used at Westgate, especially on Friday and Saturday nights, by the officers on the security detail.
TG 4724, sequentially one TG below A-16 (TG 4725), is frequently active, albeit encrypted. I wonder if that is GPD's B-1? I've not yet compared UID's to GPD's known TG's.
KR7CQ, you don't have A-8, A-9, or A-16 avoided/locked out? Have you caught activity in the clear on them?
