Hunters Ambulance has been on the Marcus LTR system for several years. I can only comment on what I monitor which is their use of the Marcus system in the Middletown area. It is my understanding that on the Marcus system, a heavy user like Hunters is given a dedicated or priority channel at each Marcus site that Hunter's uses (businesses can decide the area they need to cover and the Marcus sites need to achieve that coverage).
In the Middletown area, the dedicated or priority channel for Hunters is 463.9125. You will not hear any transmissions other than from Hunters on that frequency. That frequency comes off the Marcus site on the old ATT Microwave tower located at the Middletown/Haddam/Durham Town Line. Highest elevation around. Tower can be seen over a wide area. Site has excellent coverage.
Hunters has multiple talk groups. So If a Chair car dispatcher is talking on 463.9125 and ambulance dispatchers needs to talk, ambulance dispatch will be on the next open frequency at that site. During the day, 463.9125 is talking almost constantly. It requires a dedicated scanner to monitor it. Because there are so many more chair cars and other non-emergency transport vehicles on the road during the daytime, leaving the radio on the frequency results in missing some ambulance calls as they are shifted to another frequency at the site. Nights and weekends - the frequency is just Hunters ambulance calls.
And because it is a trunked system, you do hear all transmissions regardless of where in CT the ambulance or chair cars are and regardless of the Marcus site their transmission is actually being received at. It appears that all transmissions are repeated at all sites used by Hunters.
