I won a contest broadcast on the Taipei, Taiwan shortwave station from my home in the Midwest US listening on my
Radioshack DX-394 and a 60' dipole antenna.
They were giving away a CD called Gongs and Drums to Welcome New Year by the Taipei Municipal Chinese Classical Orchestra and you had to write in 50 words or less how it made you feel listening to it. They read my name and submission over the air and sent it to me wrapped in a local newspaper made of rice paper. I still have them both. I liked listening to their Chinese classes.
I've heard number stations, too.
I still have the unmodded radio, and there are a lot of mods for it, but I can't run an outside antenna here and the reception inside is horrible with the stock telescoping antenna.
At the time, I was more into scanners and what could be heard on them.
