NMF HF-Fax

Today's radio catches: reception of station NMF, Boston, MA, on three different frequencies with HF facsimile transmissions. NMF is operated by the U.S. Coast Guard for the marine service and broadcasts information of interest to mariners. These HF facsimile transmissions were broadcasting marine weather from NOAA. Information about NMF is found at weather.noaa.gov/fax/marsh.shtml. I think that NMF's transmitter site is actually located on Cape Cod, not in Boston itself. Receiver: Drake SW8. HF-Fax decoded using MultiPSK.
