I purchased a new (old) grid dip meter a local hamfest for $10, the Heathkit GD-1B. Built in the 1950's this grid dip meter still works great, no need to restore it and it came with a full set of coils.
I plan to use this for, among other things, finding the AL values of salvaged toroid cores.
Does anyone have the info on making our own
ReplyDeletecoils for this ? I hear , these coils are
hard to find .
