This month, the SHARC Report presents a Summer Mystery. We will discuss one of the biggest mysteries in radio, the “numbers stations” These mysterious stations broadcast long lists of seemingly random numbers. They began appearing during the Cold War, and some of them continue today. Many people suspect that they broadcast coded messages intended for spies operating undercover. We will listen to a few of them, tell you what is known about them, and let you know how to listen to them yourself. tune into The SHARC Report on Thursday, Aug. 1 at 5pm on KMUD Garberville.
