The proper term is "remote base station". A Coast guard station may
have several radio stations that they operate from one point. Those remote stations are tied to the operation point by phone line. Your signal does not get "repeated" over their system. They may transmit on more than one of those remote stations at the same time. They also listen to all of them at the same time. A repeater requires two frequencies ot operate. One to receive and one to transmit on. Channel 16 is only a single frequency.

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. http://www.navcen.uscg.gov/marcomms/cgcomms/nds.htm "Steven Shelikoff" wrote in message ...

They may be slightly curved around the horizon but they won't be much. So, whatever the power of the transmiter is, they won't reach more than 25 miles before getting lost in space. 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. Steve |
