I decided to have a closer "look" on the 1972, 73 magazine VFO circuit from a previous post.
The circuit (minus the red part):
..coil is from an old IF transformer and the tank cap was the first on hand...
turns out it oscillates at:
Now the output wave with "post processing" markers...:
it's not a perfect sine even when "stretched":
...will try other oscillator circuits in the future searching for the perfect wave....
Have a great 2013!
