Well there you have AM radio in a nutshell! ;-)
It's dead like Fred and none too soon.
You must have missed the part where I wrote that these on board stations are FM, not live, just a mix of MP3's etc coming from computers.
Land-based FM stations don't exist offshore. The only live radio out there is AM. The FM's and the TV stations can't make the trip out there.
Our ship's long range communication (other than satellite) is via single side-band AM radio and getting a thousand miles at 2182 khz (standby and calling channel) is duck soup. The VHF FM radios will let you talk to nearby ships but forget about a land link on them unless land is within sight or darn close to it.
