[sdiy] When building a White Noise module has anyone ......

[Rykhaard D.A.M.I.A.N.]

had it emitting noise, all over the place - through the air??

I just flipped on the power to my modular, to test out a new (to me) noise
circuit from René Schmitz.
Hooking up the roughly 2' banana patch cable to a VCF input, I get a lower
level white noise emitting all over the place. :O
Even with the Cutoff on the Filter down all of the way, and the input to my
VCA, down all of the way.

Another odd thing with it - the output level of the VCA, when it's between
about 10AM and 2PM is when I hear the noise.  Outside of those settings on
the VCA's output control - I hear nothing.

???

Outside of hooking up the WN module's output with a shielded cable, I am
STUMPED.  I've never had this happen before, with any other noise module,
that I've hard working. :O

Any ideas??

If it would help any - I have 0.1uF cap power supply filters all over the
board, as well as 100uF and 22 ohm resistors, on the V+ and V- inputs to the
entire board.

Thanks for any possible info, on this one. :O :)
If it's not easy to fix - I could still keep it on the board, for a source
to the Sample & Hold on the same PCB.  The noise is barely perceptible on
the power lines, at 20mV.  Seeing that though - maybe I should apply cap
filters to the PS inputs on the dual opamp, in the noise unit.
Off to investigate. :)

Take care,
Warmth and Peace,
