Med Evac is the old Greeley Air Life one based in Greeley at NCMC and the 2nd ship based in Erie.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?
Just goes to show I can learn something new every day.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.
1917 & 1918 are used by Medevac when there on the ground and for coordination purposes, same with 2362 ground operations by the aircraft troopers.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.
They could come up on a DTR talkgroup if needed, but as bob alluded to, it would unecessarily tax the sytem. Where I am, they use a simplex channel wih the responders.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?
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.
