Being in a remote location with limited infrastructure and occasional disasters of various flavors, I thought it would be a good idea to have some options to get email on and off the island without relying on local communication providers. There are some satellite phones around, but a limited number, and bandwidth is still costly. I have found two ways to get email off the island using amateur radio: APRS via satellite and via HF. I managed both with equipment already on hand and no additional expense.
Both systems rely on some sort of gateway receiving station to route the email to the internet. I’ll focus on HF because it is more robust and more likely to be available at any given time of day.
