jc: ""
If you had the schematics you would see that the oscillator and its output driver are completely resistively buffered from the cable itself.""
Since he doesn't have the schematics, it can't be called a "dumb guess", silly..:-)jc: ""
Also I deliberately put a relatively large capacitor (.033uf) to ground designed to attenuate anything over 5KHz on the oscillator and therefore improve both the S/N of the oscillator and its residual distortion, as well as to have a predictable cap load buffering any changes in cable capacitance.""Hmmm, new point of info..
When you say "ground", where are these bad currents going? Since ground is not an infinite sink that forever removes electrons, perhaps the ground currents were indeed coupling to the cable loop via some chassis path....an interesting thing to look at..
Cheers, John
