This is a program exploring the facinating world of number stations often found broadcasting on amateur radio bands. It was recorded from the amateur bands. It is placed here under the fair use rules and is for educational use only. No ownership is implied and the copyright remains with the makers of the program.
Apologies for the low volume of this recording. I suggest downloading and playing through the excellent free program Audacity where you can alter the volume levels or, listening through amplified headphones.
