Radio station noise problem

[Yup]

I just complete a circuit recently and when I turn down my guitar volume in increments the more I get a radio signal? This also increases when I turn down the gain on my circuit? At high gain and full volume everything is fine?


Can anyone give any idea what may be happening?

Thanks

Yup

hi sounds like you need to use a shielded input/output lead..maybe...

strange that it doesnt do it a full gain though..

[Yup]

I know!?! I will probably go to a shielded wire but I 'm not sure that"s the real problem.

  The ___ circuit is recieving radio and putting it into the audio signal.
  What is the tuner circuit you are using ?

Ahhh humor.................Thanks.

Post a schematic of what you're working on.  Usually input resistors are used to make a low pass filter to remedy this problem.

Any suggestion on a easy schematic software program???

I just use mspaint . For the really fast ones I use black as my secondary color (right mouse click on black) and use the eraser. That way you draw thick lines. Ugly as hell but it works .

I generally draw schematics freehand because most CAD programs are a pain.  If you want one that works well, even if it is not related to any PCB design capability, I would use TinyCAD.  It has a library that includes tubes, so it is usable with your favourite equipment even if that is something like an old Fender amp.
