You are in Waterford and are connecting to 1B (Troop F) not 1A (Troop E)?
I live in Niantic and with both the SDS100 with a whip and an SDS200 with an NMO antenna affixed to my truck, I connect to 1A, unless I am passed Exit 73 on I-95. The SDS200 scanners up at Oakdale Fire, in Troop E, but near the the border of Troop K, hit Troop E.
Where is your scanner located?
If you'd like, I can send you what I have programmed into SDS100/200 , you can just drag and drop it into your SD card (I always program to the SD card in a card reader, not the scanner itself) and see if that works for you.
