In Reply to: RE: How to solve digital noise getting into RF which is very common. posted by Michael Samra on May 22, 2017 at 03:42:06
The only solution I can think of is build a time machine and go back into the 70's.
Ok, sorry for the joke but here's what I did.
I used to have all my router, wifi, switching boxes, etc... basically my computer and stereos in the same room. As fate would have it I moved into a new house and could no longer use that same setup.
The computer is about 25 feet away and I use a TP-Link Wifi extender to my stereo area. The extender is about 8 feet from the stereo and cabled to my Marantz streamer. Computers and accessories are noisy even on regular stereos. Basically keep them as far away from each other as possible. Or if you need a computer near by use a solid state drive. It helps at least cut down on the noise.
You do know there have been health studies about the effects of the massive increased microwave transmissions from cell towers. Odd - it keeps getting shut down???

It isn't so bad on FM but for Ham or Shortwave broadcasts or AM,it is horrendous.

I have a issue with certain dacs, switching power supplies etc messing up my reception of weaker stations on fm. Interesting enough my wifi and computers don't have any effect. Also that my Fisher 400's tuner seems immune to the negative effects.
I don't have any issues on any of my audio systems however,an RF spectrum analyzer is the only way to really know how much noise is present.You would be surprised at just how much digital noise and RF interference can affect amplification,even tho we may not think we hear it. Shielding and grounding is most important,when it comes to repelling noise or interference.

Try using an oscilloscope with a florescent mag lamp. Now THAT'S distortion.
