this was discussed a while back, in your thread about measuring nhz inductors.

I experimented it based on a post by Alan Yates, who picked it up from Kainka.

very capable. the design itself doesn't have any means to stablize the magnitude so it requires a pot and a scope to function. But otherwise, it is very very easy to oscillate.
