@w7voa Good article. Thanks for posting. I'm thinking of subscribing to that magazine now.

I didn't know Eimac was still in business.

I was unaware that people were considering sending text, using advanced digital modes, over over broadcast AM shortwave. I think it's a great idea.

Do you know of any stations that are doing this on a regular basis? I mean, the technology is now easily accessible to anyone who has a pocket shortwave radio and a smartphone.
