Update: I had a chance to do some monitoring recently for this incident, it was like listening to a small city. Here are the freqs I could identify:
132.4 - Air Attack
169.75, 146.2 PL- Command Repeater (appears to be the only one).
172.4375, csq: Air-Ground Primary
172.65, csq: Air-Ground 2
167.0625, csq: Air-Ground 3
166.6625, 97.4 PL; "Crew"
167.625, no PL: likely a Tac ch.
168.25, 146.2 PL [NIFC Tac-6];
166.775, 146.2 PL "Tac" [NIFC Tac-5]
166.725, unconfirmed PL: NIFC Tac-4
168.6, 146.2 PL [NIFC Tac-3]
168.05, 146.2 PL - NIFC TAC-1
166.2375, 110.0 pl - likely a tac ch.
172.1375, 146.2 PL - likely a tac ch.
166.325, 110.0 pl - unconfirmed use
163.7125, 100.0 PL; Pike/San Isabel Work Ch.
For Aspen Acres the Regional MAC channels are no longer in use. Traffic Control points (presumably by the National Guard) are all on Pueblo County MAC (TG 4310). Given how people referred to certain channels, I suspect that different divisions have different Codeplugs. I say this because at least one if not multiple of these channels are called "TAC" by the users, despite there being many tac channels overall. Also I suspect I didn't get everything, if I had more time I probably would have captured even more.
