Pretty sure it has something to do with the numbers being some sort of encryption for messages. Someone would need to know exactly what each number meant so there would be zero possibility of civilian or other military interception. Or something.
yeah, this is pretty much what the fanatics of number stations have figured out. the lincolnshire poacher's a bit strange because it was fed through australia & korea... somehow. strong frequency?
i found a morse code station at frequency 666 (idk i was tuning ok) and its pretty interesting.
Number stations existed during the Cold War.
no stuff? they existed around wwi, i think, too.
