I did see the talk group for the old Tac-2 on the P25 system all day. I also saw another encrypted talk group (2014) that was just as busy, with UID's I have not yet logged on other channels.
I'm just guessing here, but maybe they patched in TAC-9 info the P25 system?
Nice finds Nick. I used to publish a list of frequencies that might help if anyone went to Belmont, but I just didn't have time for that this year. I'll be sure to add that one onto the list for next year.
