Over the past 6 months I got QSL cards from Radio New Zealand, NHK Radio Japan, and Radio Rossi. Many broadcasters now have submission forms on their websites where you can submit reception reports. Radio New Zealand actually sent me a link to my QSL card where I could download and print it.
The QSL card from Radio Rossi, while interesting, is a far cry from the propaganda package a friend of mine got when he sent them a reception report in the early 1980s. Great stuff describing the wonders and benefits of the "glorious workers' paradise". Of course back then they were Radio Moscow. Interestingly, that propaganda package had already been opened by the local FBI office but that's not much of a surprise given the timeframe.
