This week's Twenty-Thousand Hertz podcast is about numbers stations, particularly the buzzer, a cold war hold over from Russia. The show spends some time at the beginning introducing listeners to what shortwave radio is. Then they get into numbers stations and the buzzer.


Though there are fewer numbers stations, some countries still find them useful in the 21st century.


Here's the link for the show notes page and where you can listen.
