Back in the day, missionaries with radio amateur licenses, or who had people with radio amateur licenses, would get on 14.300 MHz to connect with hams stateside who would deliver messages, or set up phone patches. I used to be a “net control” but that was a long time ago. It may still be running, AFAIK.

I used to get on one they called the halo net, on 21.390. It was mostly for the missionaries in South America, trying to pass messages back to the states. I just lost interest in Ham radio 20 years ago. I have never gotten the interest back again.
