[Boatanchors] Millen GDO LF coil data

[Ian]

Got a new/refurbished transmitter that doesn't seem to work right?

Use the GDO to check the resonant frequency of the tuned circuits involved.

For me anyway, it's a piece of equipment I wouldn't be without.

Got rid of the Heathkit tunnel dipper that I had built not long after
building it and finding that it was much more difficult to get reasonable
results with and went back to my old original Heathkit dipper.
