I like hearing mailbag shows on shortwave stations. It's a nice supplement to the news that a station covers, and it provides opinions from people around the world. The letters also ask questions relevant to shortwave, the station, the station's home country, or current world events. Radio Havana Cuba's mailbag show is the one I hear most frequently.
I'm going to have a mailbag show on this weblog, too! Write a comment here if you have any questions you want answered, or you want to discuss something directly or indirectly related to radio. I'll try to eventually use each submission, along with the contributor's name, in a future article.
