That talkgroup has existed in the system since the early days of the system, but its current purpose has been unclear for a very long time. Maybe it was once used in the ancient times, but now it is probably buried deep inside one of the zones that no one ever bothered to look at. The only folks...

The county fire department radios went live with what I am guessing is a new A zone sometime in early December. I have no clue on the procedure for how talkgroups are assigned for calls, but they seem to have replaced the previous C zone assignments for most calls. I assume A1-A3 are Red...

They were in reserve battalion chief trucks.

Yes, SQ in their CAD stands for Squad. From their social media, they are temporary units to handle the excess call volume related to the extreme cold weather from this past week. They roam the district and mostly self assign calls. They are not based at any one station or part of any normal...

It was sold to the county as coverage for the Stone Canyon Outdoor Education Center area and approximate six-mile section of Highway 105. It is likely intended to be a gap site for portable radio coverage in the area. The existing South Simulcast licenses were modified in October to include the...

They have maps on their photography website in the album linked below. Those are the best you are going to get unless SMFR releases their GIS datasets to the public. https://www.southmetro.photography/Misc-Photos/2019-SMFRA-Map/

You could program them in just in case, but they are not as commonly used because they are interstitial frequencies that overlap with VFIRE21, 22, and 23. If you like being able to hear as much as possible, then I would encourage that you try out programming stuff that's further away just to...

Colorado has some great radio propagation thanks to the geography which allows you to hear sites, systems, and talkgroups from the surrounding counties if you are interested in listening to the stuff happening elsewhere. If this interests you, then I would suggest expanding your programming to...

First, set up a Group ID (5) separate from your talk groups and use the P25T Sub-Group column to set up the tones you would like the pager to unmute for. You may also set up the Alert Mode column for how you want the pager to behave when it receives the tones. You will need to set up a separate...

I have checked and can confirm both are still on the simulcast and operating in Phase 1. Are you able to hear other Adams County agencies using the simulcast, especially other fire departments? If you can hear other fire departments, then it might be the departments being avoided. If you can...

If this was MAC 11 on the 18th between 15:30 and 17:00, then it was CSP Air 1 flying N202SP working with Pueblo PD on the operation covered in the KRDO news article. They identified themselves as "CSP Air 1" a few times, but everyone else shortened it to "Air 1" when talking to them.

I think that the law enforcement exemption might also cover Mode S. Denver has great MLAT coverage, so a Mode S aircraft should show up on ADS-B Exchange. They might be operating with Mode A/C because you can sometimes see them as an unknown TIS-B aircraft when the airspace is busy. My point is...

It depends on the talkgroup you heard them on. If it was a Denver Metro talkgroup, then someone might have dragged the talkgroup into the area (against best practices) and you were hearing operations in the Denver Metro area. Air1 almost always stays in the Denver Metro area unless there is an...

SAME/FIPS codes are unique for each county. Denver is 008031, Boulder is 008013, and Larimer is 008069. The reason you would hear an alert for Denver or Boulder if you have a SAME location code programmed is if the alert being sent out covers multiple counties that include Denver or Boulder. A...

I think Denver's EDACS was the only public safety system in the state that had the feature turned on and it was used occasionally. That went away when they moved to P25 and I do not think any P25 system in the state has private calls enabled other than maybe Xcel's system.

HIPAA has an exception that allows for unencrypted radio communications. Speaking of exceptions, patient reports by radio is an exception for many hospitals in Colorado and phones have been the norm for decades. The hospital talkgroups still exists in the system and hospitals should still...

It is probably not too useful at this point, but RadioReference has a built in site map for all trunked radio systems that can be accessed by going to the Sites and Frequencies section, clicking on the unlabelled hamburger button to the right of the heading, and then selecting the Site Locations...

No, what I said was that some of the radios are Fort Carson Fire, but others are used for what sounds like radio patching for schools. I also said that the range is possibly many different users and cannot be simplified to just one agency. 46#### is 10000 radios and Fort Carson Fire does not...

Are you seeing any "Grants" in the Action column or are you seeing "Joins?" A join means an affiliation, which means that the radio is set to that talkgroup. There is no voice transmission being made, so there is nothing to hear. It is hard to identify what the talkgroup is being used for if no...

Berthoud has one license for the one frequency of 453.0625 MHz that they could be using in simplex. https://www.radioreference.com/db/fcc/callsign/WQVE402 It is also possible that they could be using cell phones for daily operations as that is becoming a popular option given the cost of a...
