Here's what I've been playing with so far.
I haven't put much in the way of quick keys in these, except overall on 'Local' for the systems. Here's my philosophy on quick keys.
0 to 9 are for services you might want to hear regardless of location.
1 - Fire
2 - EMS
3 - Police
4 - Business
5 - Recreation
6 - Public Works/Roads
7 - Utilities (Gas/Electric)
8 - Airport
9 - Tri-Services/Interop
0 - Miscellaneous/Hunting
I do the same with Group Quick Keys inside a system, so I know that if I want to hear the police, I just have to turn on GQK3.
I use a slightly different method for regional keys. I group areas that can be heard together/work together and assign them a number from 10 on up.
The 'local' file has examples of this like so:
10 - provincewide
11 - Calgary/Rockyview/Tsuu T'ina/Stoney
12 - Foothills/Eden Valley/Kananaskis
13 - Bighorn/Banff/Clearwater/Mountain View/Jasper
14 - Crowsnest/Vulcan/Willow Creek
15 - Forty Mile/Lethbridge/Warner
16 - Blood/Cardston/Pincher Creek/Waterton
17 - Kneehill/Wheatland/Gleichen
18 - Cypress/Newell/Special Area 3/Taber
19 - Lacombe/Ponoka/Red Deer
Take note, the data in Local.hpe is not all-inclusive containing everything I'd listen to. I do leave the "full database" entries switched on for most of these as well. The RRDB is accurate enough for most of it that I feel comfortable using it; the stuff in Local is stuff I want to customize or channels I'm trying to determine the use of, etc.
Before anyone asks - I have not included my custom Calgary Digital Radio system and a couple of other systems in the file I'm sharing with you. Sorry; I just can't share it without running afoul of the rules.
All three files below have some OFT (one-frequency-trunk) systems in them. For those who don't know, OFT is Uniden's way of handling talkgroups and radio IDs on "conventional" P25 frequencies. If you were to just program them as conventional and assign a NAC (or search), you wouldn't see TGIDs or RIDs, even though conventional P25 uses them.
Local is stuff around Southern Alberta that I listen to on a regular basis.
700 Interop takes the NIFOG 700 MHz channels (which correspond to the Canadian interop channels) and puts each one in its own OFT system - see above for why. You'll want to set the 700 section of the national system "CAN - Interop" to Avoid if you use this one, or else you'll get double data (once from the main DB, once from the favorite).
AFRRCS is of course the AFRRCS data as drawn from the published licenses and everyone's monitoring. All the single-frequency sites (in VHF and UHF backhauls) are entered as OFTs; the 700 MHz sites are entered as one large system. Lock out (avoid) the full DB version of AFRRCS unless you want to hear double.
