Hi,

I have several small measuring instruments in my shack, but I have
always been unable to find plans to build a DIP METER for use in
LF Freqs. I already have a LEADER DM that begins at 1.5 Mhz but I
would like to be able to measure resonant circuits at say 40 Khz
or 470 Khz. Is there a thecnical difficulty I should be aware of ?
Any help or reference appreciated.

Millen used to make a set of LF coils that plugged into one of
their GDOs without any modifications to the unit. It seems then
that you simply need to make an appropriate coil (old wave-wound
IF transformer coils perhaps) and to draw a calibration graph for
it. I was thinking of doing just that but on the other hand,
should anyone have a set of LF coils for sale for the 90652 or any
information on them, I would be most interested.
