Uses DMM as readout. Ability to set a signal to 100kHz is also required
to
calibrate.

I've gone all these years without one but I might give this cct a try.
Any idea of the twin screened / coax? cable characteristics, min/max
lengths
?, just cruddy old audio interconnect shielded cable sufficient ?

I'd use some of that twin flexible stereo cable (grey?) if you have it but I
have no more info on the circuit.
