It seems that MedStar Ambulance Service is now using the Chatham-Effingham TRS for communications between MedStar dispatch and their ambulances. Throughout yesterday, I heard TG 7920 active with communications between MEDSTAR and MEDSTAR ## units.
If TG 7920 is indeed MedStar dispatch, it is about time that they moved onto the system with everyone else.
I first heard TG 7920 active back on 7 January; ID Tracker caught several "kerchunks" but never any voice traffic. I plan on running ID Tracker some more in order to confirm and ID on this talkgroup.
