Re: LF: Nostalgic stuff of early radio transmissions

Hi Stefan,

nice video, thanks for sharing. I liked the Röhre at 9:39 (not my
favorite 807 though it has the same glass envelope) as well as the big
transmitter tuning gear a bit further down on the clip ;-) You're
right, the language barrier isn't really a barrier...

Good stuff.
