Grid Dip Meter Circuit Found
 

What looks like a very nice circuit is available at Harry's site.

This site includes all the info you would need to contruct your own
dip meter, including coil winding information.

Please forgive me if this has been noted before; this was the first
site to come up on Google with the request of "Grid Dip Meter
Circuit."
