That's about what I reckoned.

Sending a helicopter to get a cross-bearing on the jamming to confirm it is from Jewell Island won't take long. Then it's time for the Warden to answer difficult questions, or things get exciting.

Sounds right.
Here is a pretty good
overview of what the USCG Northern New England Sector has.
The helicopters appear to be all located at Cape Cod. Would it be quicker to spin up one from there and fly 60 miles or man a 47' MLB or a 25' Defender class boat to motor eight miles and check things out?
For that matter, the USCGC Jefferson Island (WPB 1340), a
110' Island-class patrol boat has a home berth in South Portland. If it's not away on patrol somewhere hours off, it might be available to scoot over to the island. In addition to two M2 machine-guns, it comes with a 25mm autocannon, so it's properly armed. I don't know what the radio equipment is or whether it would add to their data.
Thales HF medium-powered, High-Frequency Automated Link Establishment (HF-ALE) radio communications system tell you anything about the communication capabilities on their cutters?
Or this list of USCG technological projects?
