Confused about channel programming

[malignantpoodle]

Whenever the action gets hot with the police, they always switch to another channel. They may say something like, "all units involved with blah blah switch to tac 2". Or, "unit 295 switch to tac 1 for further information".

And then of course you hear nothing else.

So, I did some looking and came up with this listing for those channels;
[POLICE]
1809 14-021 District 1 Dispatch
1810 14-022 Services 1
1812 14-024 TAC 1-1
1813 14-025 TAC 1-2
1814 14-026 TAC 1-3
1825 14-041 District 2 Dispatch
1811 14-023 Services 2
1828 14-044 TAC 2-1
1829 14-045 TAC 2-2
1830 14-046 TAC 2-3
1841 14-061 District 3 Dispatch (Future Use)
1928 15-010 CLEER (Patched to 460.425 CLEER)

Found it here;

For other channels, the frequency in mhz is given. But not for these. I'm new and dont' understand the numbers nor is there a key for them on the site. Any insight greatly appreciated, thanks.

Those are talk groups for Aurora City. They are using a trunking system. You need to program the talk groups in the Aurora city system. You can find a list of all the talk groups here: Aurora, City of Trunking System, Aurora, Colorado - Scanner Frequencies if you don't know what a Trunking system is try reading this Wiki to help explain how the system works Trunked Radio Systems - The RadioReference Wiki
