Now and then I hear "Med Evac 1" asking for a med patch. Where are they out of? And is there any truth to the rumor that the medical helo's in Colorado might get their own DTRS talk group?

Right now, airborne units are not allowed to use the DTRS, since they will most likely hit more sites than they need to for their mission, and cause an overload of those sites.
Down here, they are using 800mzh simplex channels, which are available on DTRS radios.
Why are there TGs listed in the Database for MedEvac 1917, 1918 and CSP Aircraft 2362? Not trying to be smart mouth, and it makes sense they would not be on DTRS but why the talkgroups? I do know that they use FERN in boulder County for landing medical aircraft.
Just goes to show I can learn something new every day.
I always thought FFL, etc. could come up on any channel needed. Of course
the norm are FERN & NLEEC. Does the NO DTRS rule apply to CSP aircraft
and military too?

I know CSP aircraft operate off of CSP 3 in my area. In talking with a trooper, no they do not have a DTR radio in the plane.
Because frequencies are re-used at several sites in the system and an aircraft at altitude can "hit" multiple sites. For example, let's say you want to talk on site "1" and the control freq is 852.1. When your chopper is at 5000 ft, you not only have line of sight to site 1 but also to sites 2, 3, 4, and 5. If 852.1 is used at any other site in your line of sight "view", you'll key up that site in addition to site 1.
So does Denver's multi site system work differently then? Or how to they make sure Air one does not take up more then one site?
Yes no comparison between Denver EDACS system and the statewide DTRS. They operate much differently.

The difference is that the Denver sites work to complement each other. There aren't different TGs on different sites on it, where the DTRS sites _may_ host different TGs.[/QUOT
Thank you Sir! And as always, thank you for your service!
but yes they do.....alot of our ops for non-vhf cars are on 800 simplex channels
