Group Boston has their primary on the Hancock tower in Boston, plus repeaters in
Plum Island north, and Marshfield south.

Baltimore has a repeater at the C&D Canal (as well as south); and Chincoteague
has one in Ocean City and one to the south. Both are within about 60 miles of
the Jersey coast.

These are all on high towers, and broadcast at much higher than 25 watts. If
there is any ducting to be had, these signals will find it. In Boston I often
hear Portland and Woods Hole, where the repeaters are 50+ miles away. Sometimes
I get Bar Harbor.

Here's a set of maps showing the repeater locations and the "nominal" coverage.

Well, not really. It all depends on antenna height. From the Jersey
shore, not only can I talk to the Cape May CG station, but also to
Baltimore and Chincoteague, Virginia. I have fairly reliable
communications with CG stations up to over 100 miles.

ducting...dangerous to rely on for reliable communications...

It must be a pretty reliable duct because I hear the Baltimore CG
station almost all the time from the Jersey Shore. It's faint of
course, but perfectly readable.
