All,

Thanks for the replies. I think the mystery is solved. I believe I am
hearing the DGPS station in Annapolis on 301kHz. I hear the same type (but
weaker) signal at 307kHz, which is the DGPS station in Hagerstown, MD.

Thanks all!

John

There's a USCG DGPS station at Annapolis, but it's on 301.0 KHz.
