I remember hearing this actual broadcast from Radio Beijing on my Shortwave live on April 4, 1989.....

By the next hour, these announcers were replaced by others and they were back spouting the party line.
I’ll never forget the time I was in Augsburg, Germany and heard a guy on his CB radio driving out of Boston. This was on my FLR-9 antenna back in the early 80s :-)
I had a Heathkit SW-717 back in the day, worked quite well. Picked up Radio Prague, Radio Budapest, RSA, Radio 4VEH (Cap Haitien, Haiti), etc.
Actually Ham radio operators also have EchoLink, the ability to use the Internet to communicate through computers or radio or even repeaters. I can use my computer here with microphone and speakers but reach an EchoLink node in India and have that node broadcast on a radio and reach someone via radio.
