Marine multi-band Ham radios

Marine multi-band Ham radios

by Bill Morris  With the growing array of communication options for offshore sailors, it is easy to be dazzled by the growing availability of satellite phones and even digital television. In reality, though, hardcore voyaging sailors by and large depend on the flexibility and independence afforded by amateur, or “ham,” radio, which allows you to speak with other radio operators on both land and sea anywhere in the world with no monthly or per-minute charge to worry about. As long as you have the requisite FCC license, at least General Class, you can rag-chew to your heart’s content from any…

High frequency marine SSB radio propagation

High frequency marine SSB radio propagation

Even though satellite communications is taking an ever bigger slice of the voyaging communications pie, high frequency (HF) marine SSB is still used by voyagers. Here is a rundown of the basics of HF radio signal propagation to aid in using it effectively. HF radio energy traveling through the atmosphere or through space is subject to very little attenuation and the energy would arrive at the receiver as strong as it was radiated. Not all radio frequencies behave in the same way, however. Extremely high frequencies, higher than 10,000 MHz, can be attenuated by moisture and dust particles in the…
