 |
|
Hi Group , I have a problem with my home computer and or monitor
generating noise that is picked up on my HF ham radio rig . In order to
cancel the generated noise , how might be the best way to ground or
choke out the noise directly from my home PC ? I presume I first need to
determine the frequency of the unwanted noise signal and then build a
balun or a choke to ground or cancel the noise, maybe !!!
One thing is for sure , the problem exists when the computer is on
and it generates harmonics that interfere with HF radio on Amateur Radio
Frequencies .
Thanks for any good help in advance , rijo |

Is your computer plugged into a properly grounded outlet? Got all the
metal slot covers in place? Computers produce a lot of RFI, it can be
tricky to keep it contained. |
