CW repeating on 156.2250 marine CH64A every 30 minutes. I live 200+ miles from the coast but fairly close to the Savannah River. The only ships that can navigate this far up the river would be rather small. I started scanning the marine band after reading about hunters illegally using it. Needless to say, I was surprised to hear CW. I guess this a navigational aid or something? I don't know Morse code and have no way to record it (that I'm aware of) to decode the message.
