You'll definitely want to program in the marine frequencies, particularly channel 16 (156.80) which is the international distress calling frequency. Just google "marine frequencies" to get a list of all the frequencies. You can start with this link. http://www.marinewaypoints.com/learn/vhf.shtml Then try a google on "marine frequencies SomeCruiseLine" or "marine frequencies SomePortName". If you have a shortwave reciever that recieves ssb you can also program several USCG hf frequencies and other common hf marine freqs. 73, Ken -N5SWR -----Original Message----- From: For blind ham radio operators [mailto:[log in to unmask]] On Behalf Of Jim Stevenson Sent: Thursday, February 22, 2007 5:37 PM To: [log in to unmask] Subject: scanning on cruise ships?
