Main frequency is still 44.74. They use this freq to contact syscom when they are airborne. If a helicopter is at it's base, syscom dispatches them by phone. Also keep in mind that syscom will communicate with a helicopter using only the closest base station radio. For example, if syscom is calling TP8 and TP8 is in western MD, they will use the base station in Western MD, and you probably won't hear any part of the call from central MD. Because SYSCOM only communicates with troopers while they are airborne, there is only a need for a small number of base stations around the state.

Thanks, Matt, I didn't know that about the base stations, that explains why I never hear much.

Trooper 5, WMD

Trooper 5 based out of Cumberland will use frequencies available in the area where they fly.

123.450Mhz...Air to Air is a favorite when talking to other aircraft or coordinating with another MSP helos.
123.900mhz is also used

Both of the low band frequencies are used on a regular basis as mentioned above.

Keep your ear open on ALL the local 911/EMS dispatch channels along with your local MSP dispatch channel for bits and pieces of conversations from the Helo.

Ex: Here in Cumberland you may hear multiple conversations as they go on a mission.

1. Cumberland airport Unicom, Trooper 5 a helocopter, outbound runway 23, heading 270, accending to 4000 feet Cumberland. 122.800 Mhz
2. Trooper 5 to Syscom, 10-8 to the MV accident in Cresaptown. 44.740 mhz
3. Trooper 5 to the Cumberland barrack, 10-8 to Cresaptown, MV accident, do you have a trooper on the ground at the scene? 39.240. mhz
4. County 911, fire channel 1, 10-8 to Cresaptown, who is our fire ground contact and landing zone for the MV accident? 33.780 mhz
5. Call 2, med 3 or 6 to talk back to the hospital on the condition of their patient.

Enjoy

Not likely that anyone will be calling for Trooper-8 anytime soon, but good explanation.
Also, for the geeks- this is described as voting receivers and transmitter steering.

Why wouldn't anyone be calling for Trooper 8 anytime soon? Did MSP downsize their aviation fleet?

EDIT: Wow, just looked at the map. When did that happen?

After Trooper-2 crashed, MIEMSS changed the trauma decision tree to decrease unnecessary flights. The whole fleet saw less transports and someone had to go.

FYI:
Troopers also have radios to talk directly to the FDs in their flight zones. You hear MontCo and Troopers (USPP Eagles, too) talking on the MontCo TRS system during river seaches and for instructions at MVAs (they also talk directly to units on the ground on this system).

I hear them on the Medivac Unicomm freqs.122.85 and 123.05.
