There was an incident on Tuesday (11/16) where a Medivac chopper from Erie was requested by Mountain View fire department (acting as "Highway 66 command"). The chopper was asked to use what sounded like "STAC B" but could have been "STAC D" to coordinate a landing zone. The CODTRS database page has a STAC 5 listed near the stop as an analog simplex channel of 853.7875 MHz 156.7 PL. The only place I could find a STAC with a suffix of a letter was STAC D listed listed in the feed notes for the Larimer County Live Feed. It lists STAC D as the same freq as STAC 5.

Is STAC D and STAC 5 the same thing? Is there a STAC B?

If anyone wants to hear the request I'm referring to, it's in the Boulder County Feed Archive for 11-16 at 5:03 pm. It's mention right at the beginning of the file and again at the 5 minute point in the file.

Thanks, Rick; that book looks really cool.

I wonder if they have any regulatory problems because there's a *corporation* running the network; public safety traffic goes over it, right?

What kind of regulatory problems do you anticipate? The corporation is made up of the member agencies who use the system and most or all of those agencies are cities, counties or the state.

Specifically, that the *licensed operator* of the system is not itself a public safety agency; I wasn't sure what provisions may have been made for such 'intermediary' situations in various FCC regs, for example. Since it's running, I assume provisions of some sort have been made, but, being a reg-hound, I'd be curious what and where...

Thanks for the link. :)

So, there is no STAC 5.

The CODTRS database page should read something like

STAC 853.7875 MHz 808.7875 Mhz (input), Statewide analog TAC temporary repeater
STACD 853.7875, Statewide analog TAC Simplex
both with 156.7 PL

I'm not sure where you have found that CCNC is the licensed operator of the system. If you browse through the database for this system here on RR, you will see that the frequencies are licensed by various state, county or city agencies and not CCNC. CCNC merely sets policy and direction for the system.

And supplies, manages and operates the system's equipment, Greenthumb, no? I would have thought that the licenses would require *the licensee to be in direct control* -- or do I fail to understand public safety licensing, as opposed to all the other FCC license grants I've ever read?

CCNC does not, the members themselves do (and they are the licensees). Look at it this way: DTRS is a shared system and many, many agencies have their assets connected to the system. CCNC is the forum by which all of those agencies collaborate on how the system should be ran from a policy perspective.

No, the licensees are in direct control of their assets, you're just not understanding how CCNC works :)

Okay, fixed in the description. Since our scanners don't care about the repeated or simplex version, I amended accordingly.

Apparently. :) I'll finish reading the manual, and then come back to it if I still haven't figured it out.

My scanner cares. ;) I often program the repeater input freqs into my scanner. Up in the mountains, especially in Boulder County where the repeater can be many miles away, the local units can often be heard much better on the input freq than the repeater output freq. (Red 6 or SO Yellow are good examples of this).

That will never be the case with the STAC channel because a temporary repeater would obviously be set up in the area where the incident is occurring. So it's fine they way you have it. :)
