MF,

Here's the link to the schematic and image to the 630m band VFO with adjustable "nostalgic" sound.

PS: Not as authentic as Louis' tube VFO signal but it has a nostalgic and entertaining component anyway :-)

Hello Clemens,

LOL, that is my special calling card! A feature!

I will publish the circuit for that VFO very soon. It is almost complete. The circuit is very comfortable, a free running oscillator but the chirp is not realised as you expect.

Hi Stefan

tonight your CW signal has a quite strong personal note (a very special tone).
Bug or feature ? :-)
