I was living on the eastern edge of the Midwest, so I could easily pick up broadcasts from Canada, the Caribbean and Western Europe. As far as programming goes, I just remember news and foreign languages. More influential was the warp of voices and sounds and the waves of static I could control with the tuning knobs. It terminally effected what my ears enjoy.
I really wanted to get into QSLing, but either didn't quite understand it or was unable to listen to a show long enough to get the contact information, or maybe I just didn't know how to send a letter to St. Lucia.
QSLing was contacting a broadcaster to let them know their transmission was heard. Broadcasters wanted to know how far their transmission was travelling and listeners wanted to collect the QSL cards the radio stations sent. While it was primarily a practice for ham radio operators, many shortwave stations did it as well... and still might.
I mention all this because my pal T. Carey sent me this QSL postcard he scored somewhere and it sparked fond memories of sitting in my room with headphones on and basking in the glow of the radio dial.
