The other day I had occassion to respond to a Coast Guard request for help in trying to pinpoint a disaster call. I was amaized that the signal from the Coast Guard was exceptionally clear and I assume my was clear as well since there was no request to repeat any of the conversation.

I'm located about 85 miles from the Charleston, SC sector. Are these signals direct or are they transferred and amplified along the way.

The Coasties have a network of high-mounted, high-gain
antennas. Here's more info:

It has been common for the Coast Guard to have a network of remote radio installations which link to a central radio monitoring station. These remote receivers and transmitters are situated to give good coverage of the area which the central monitoring station is responsible for.

In the Great Lakes the Canadian Coast Guard radio service, for example, is run from a station in western Lake Superior, and it is common to communicate with them from two hundred miles away.

Very interesting! Thank you for the link Chuck. Looking at the Charleston Sector map I see that I was sitting almost exactly at the Myrtle Beach antenna location.
