I don't have a system yet. My
boat does have an
Icom M600
marine SSB that is usable for HF email. I will need a
modem and the
wiring to complete the system.
There are several good sources on the net to learn about HF email. There is a free system that is used on the Ham radio frequencies called winlink. (winlink.org) As it is on the Ham frequencies, you are subject to the limitations of the
license, such as no for profit business allowed. You have to get a
license in most new countries you want to communicate from as you travel. This is mostly an exercise in paperwork and
fees once you have a ticket from your home country.
You can use the same
hardware on the
marine HF frquencies. This requires a subscription of about $250 a year. (sailmail.com). It allows
commercial use, and use from countries that allow use of marine SSBs.
There are a couple of other systems out there as well, but they all use the same
hardware. See hfradio.com for more details on the radios you can use. The radio is like your
phone line. And, like with a
phone line, you also need a modem. In this case a
pactor II modem (
http://www.scs-ptc.com/). And of course you need a computer. Most use "airmail" as the email
software.
Good luck with the ham ticket. I have been a ham for 28 years, since I was 12.
