[sdiy] VCO bleed through to other modules

[James Patchell]

Grounding and power supply distribution is a bit of an Art.  So is signal 
distribution.

It can be quite frustrating before you learn the ins and outs as to what 
exactly is causing the problem.  And even for somebody who has a lot of 
experience, trying to find such problems can be annoying.

All I can say is read literature, listen to what others say on the list, 
and I am sure you will eventually find the problem.

I have my own way of doing this...I have found by running two wires to each 
jack ( a signal wire and a ground wire), seems to keep things nice and 
quiet.  I do this, despite the fact that on some of my panels, the return 
signal of the jack is connected to the panel...it may seem silly to run all 
those ground wires when electrically, they are not needed (but 
electronically, they seem to be)....Anyway, that is what I do...I don't 
know if it will solve your problem or not...as there may be something else 
that is causing your problem that needs to be fixed first...
