I don’t personally assign departments to quick keys on trunk systems. I’ll just lock out individual departments/talkgroups as they appear. I instead assign the sites to those department QKs.
How I have my programming (everyone does it different)
QK 01 - SRRCS List (Sacramento system)
QK 01.01 - SRRCS System
QK 01.01.03 - SRRCS Site 03 (usually turned off)
QK 01.01.12 - SRRCS Site 12
QK 01.01.13 - SRRCS Site 13 (usually turned off)
QK 01.01.14 - SRRCS Site 14 (usually turned off)
QK 02 - Other Trunked Systems (usually turned off)
QK 02.01 - EBRCS
QK 02.01.01 - EBRCS Site 01
QK 02.01.02 - ERBCS Site 02

QK 02.01.10 - EBRCS Site 10
I have about 15-20 (can’t remember off the top of my head) different public safety trunked systems in that QK 02 favorite list, and I turn them on and off as I’m traveling through the state.
QK 03 Conventional Systems (my local county and surrounding counties plus 1-2 more counties beyond those surrounding).
QK 04 Federal Agencies (FBI, FPS, USFS, USCG, etc.)
QK 05 State Agencies (CHP, CSP, DFW, DOT, etc.)
QK 99 SRRCS Input Frequencies (if I’m close to an incident but can’t get a signal on the site due to simulcast distortion, I’ll listen to the input side to at least hear the units).
I have some other stuff (Business, DMR, LTR, NXDN, CDF Statewide Load, some testing lists) on other QKs but didn’t feel the need to list them above.
