Unusual Radio Broadcasts and Numbers Stations

Ive been reading up on Numbers Stations, and found it very intriguing.

A friend mentioned to me last night that he was on StumbleUpon, and a page came up talking about this radio broadcast that is coming from somewhere in Germany. The broadcast is this one guy, talking in German, about mostly nothing, and It has apparently been going on like that for the last 40-45 years, every day, 24 hours a day. What's even crazier is that they said it is a non-repeating broadcast, so it's not previously recorded, yet the guy's voice has apparently not aged (The government or whoever it is keeping track, has shown samples of recordings of the broadcast from the 70s and 80s, and recent recordings).

I found all this interesting, but couldn't find the web page my friend read about this from. All my searching lead me to articles on Numbers Stations, which might actually be what my friend was talking about, but those things transmit mostly beeps and other noises, with the occasional creepy song playing, or someone reading groups of numbers. Numbers Stations, for those who don't know, are radio towers that governments use(d) for spies to receive information that they didn't want to enemy to know about.

So, does anyone know anything about the German guy and his broadcasts?
