Numbers Radio Stations

[DRM]

Did anyone here ever come across these during the 70's & 80's, I used to pick them up at night on short wave, they would usually have a German or English voice reading out groups of numbers, that were basically messages to spies in the field, when they came on air they usually had a musical box theme tune, which used to be used as a name, eg Britain had the Lincolnshire Poacher, which opened with the tune of the same name, I was reminded of these stations by the Ice Cream Van that comes around these here parts, the chimes were very familiar, until it came to me, Swedish Rhapsody, the numbers station that transmitted from Poland

Theres an audio sample on the link, strange how something can take you back 45 years or so!

Yes. I remember picking them up in the 80s sometimes.

 

[Drago]

Yes yes. As an avid SWL before I got my ham ticket I heard a few.

I just remember listening to the radio one day as a kid in the late '80s'/early '90s' and it had nothing but morse code on one station/frequency.
My brother and a friend heard it too.

I heard it a few times after that, but there was also another one that just had electronic beeps like you'd hear from an old internet modem/router or similar.

The Morse ones I used to pick up were just strings of numbers, - - -.. - -… …- -
