John KN5L,
?So far it looks like you are the only one to have actually run with the ball.
?Do have any thoughts about actually building this in an instrument?
As always once you get to 1MHz and up strays become
important to minimize, but, apparently a Q meter can be built that does this.
? I ask because, I would want a variable capacitor, I would also have a difficult time
measuring a 6 inch diameter coil on the small pcb you have.
?I made the suggestion that unless we can find a better way to make the 50 to 1 transformer so it is wideband,
?we may have to have 3 switchable transformers for low, medium, and high frequencies. The OPs design goal was
1.5MHz to 150MHz. I received no response on the idea. I have enjoyed this thread and your posts.
