Excellent thread idea. Nice to see someone being positive for a change!
Here's what is in my favorites lists:
Inside Calgary:
Calgary Fire
Calgary Airport ground emergency airband frequencies - sometimes there is chatter on here that is interesting
ENMAX - locked out 99% of the time but during outages or problems it can be useful
Calgary Transit - I don't listen but it's in the scan list in case something major happens and I want to see if there's anything worth hearing
ATCO Gas - same as ENMAX, but also still trying to figure out which talkgroups are which
Sundance LTR - still a whole bunch of people renting/leasing radios on systems like this, various mildly interesting comms going on. I think there are several TGs for the new cancer centre construction, or possibly for the SW ring road project - lots of dump trucks talking about moving loads.
Prairie Mobile LTR - Frequencies licensed for use but nothing heard yet, still in the scanner in case they turn the system up and it becomes monitorable.
STARS Calgary - comms are still carried on their UHF repeater.
Alyth Yards - I don't listen to regular railroad comms but I do have the new NXDN frequencies programmed in so I can confirm their RAN and any user IDs etc.
School buses - First Student, Southland, and Willco are all on monitorable systems. Again I don't keep the day-to-day comms unlocked, but the safety channels are open and I can unlock the other stuff if something piques my interest.
Wi-Com Solutions - formerly Tac Mobility, this is their MotoTRBO rent/lease trunk. Tons and tons of users on here, some long-term like Palliser Hotel, a lot of seemingly transient (coming and going, one day/week to the next) users as well.
And there are countless DMR/NXDN systems or channels - everything from one-frequency trunks/simplex channels to multi-frequency trunk systems owned by various businesses and entities all over the city that I'm trying to discover the right codes for (i.e. color code, RAN, TGs, etc). A lot of them share the same frequencies because they are intended for low-power use in a small area (461.6125 is a good example of this, with dozens of users all over the city), so sleuthing out the right codes for a specific user is a real challenge. Some of the users that I am listening to or still figuring out include: the Drop-In Centre, Genco Distribution (Canadian Tire's warehouse facility), various Prairie Mobile sites/freqs, the Saddledome/McMahon Stadium, various Canadian Football League freqs (it seems every team has a frequency pair with DMR modulation - I presume this is coach-to-QB headsets), U of C, MRU, various rent/lease systems from two-way shops, Heritage Park, Air Canada, FedEx, and WestJet trunk systems, KGL (construction company building the SW ring road), and so on.
Outside Calgary:
RCMP - still able to listen to them for a period of time, but within 18 months or so that will go away.
Firenet - both AAF (Alberta Agriculture & Forestry) Wildfire ops and Conservation Officers are on here.
Fireline/Tankers - simplex and aviation freqs used by AAF Wildfire crews.
The ATCO Gas system mentioned in Calgary is also used outside the city.
Volker Stevin - maintains the highways in most areas I drive.
Fire Departments - surrounding Calgary there are a lot of departments that are monitorable. Not including the ones that are (only) on AFRRCS, you can hear Redwood Meadows, Cochrane, Nakoda, Tsuut'ina, Exshaw, Canmore, Kananaskis, Crossfield, Madden, Irricana, Chestermere (on NXDN), Langdon, and Wheatland County and Strathmore (on TRBO). Airdrie Fire is the only local one I know of that is encrypted (or plans to be). Kneehill County Fire is supposedly on DMR/TRBO, but I can't receive them from as far away as I am.
Like in the city, outside the city there are tons of businesses that are on both analog and DMR/NXDN systems to be monitored or figured-out. Some examples are: Spruce Meadows (licenses imply that there is a TRBO or NXDN system there, I forget which), Southland Transportation (mentioned above in the Calgary section, they have a wide-area NXDN system), City of Chestermere (NXDN which includes Fire as mentioned above plus at least their CPOs as well), Foothills School Division buses (new NXDN channel), a DMR Tier 3 rent/lease system run by Nextcom in the Okotoks area, a NXDN system of some kind that just showed up in the Cochrane area registered to Sundance Radio, various rent/lease frequencies for Turris, a NXDN frequency at the Grey Eagle Casino on the Tsuut'ina First Nation, various DMR systems at Walmart distribution centres inside & outside NE Calgary and Balzac, and virtually countless other businesses with as-yet-undescribed frequencies and/or systems.
And then, after all of the above, there's...
AFRRCS:
Lots and lots and lots to listen to on this system. Depending where you are, it may seem quiet or unused, but you have to remember that trunked radio systems only propagate conversations to tower sites where a radio for that conversation is registered. If there's a fire in Cremona, odds are good that you're not going to hear it on a Calgary tower site. (Due to the way radios roam, you might pick it up in Cochrane or maybe rarely on Spy Hill in Calgary - but most of the time the system will stick to towers nearer to the user.)
Here are the agencies I have logged just in the local/regional area in the clear on AFRRCS:
Okotoks CPO (Community Peace Officers)
Black Diamond Fire
Blood First Nation PD
Turner Valley CPO
Turner Valley Fire
High River Fire
Black Diamond CPO
Rocky View County Fire
Cremona Fire
Clearwater County CPO
Vulcan County Fire
Foothills County Fire
Okotoks Fire
AHS EMS (mutual aid channels)
Calgary Police
Airdrie City (possibly CPOs only)
Redwood Meadows Fire
Canmore Fire
There is lots more that I can't hear from my local area that is monitorable as well. Furthermore there are all kinds of agencies testing, either with radio shops' rent/lease radios, or using their own as-yet-unidentified agency radios and talkgroups. There's probably a dozen agencies I see every now and then both on my recordings and on PRO96COM or Unitrunker that have yet to be figured out.
