So here is the story. The Mount Sunapee LTR system was in use by resort staff members. ID 1-01-100 and 1-03-130 were used for operations. Golden Cross Ambulance was the EMS provider, so I would assume that 152.285 could be used as well as New London Dispatch frequencies. As for Newbury police, there were only two there, so I think they just stay on their normal channel. Now for the weird part. They appeared to have one contract armed security guard (or cop from another town) there with what looked like a DMR radio even though he was the only one at the event with that type of radio.
