This maybe a bit off topic but I recently discover, by accident, that my K3 been picking up noise from my computer monitor which can be seen on the P3-VGA as a 1-2 S unit uptick in background noise on 40 - 80 meters. Turn the monitor off and it drops. The monitor is a Samsung unit and is the only one of the three I have that cause the "inference." Has anyone else experienced this problem??I have tried all the 'usual' fixes, chokes, re-locating coax & cords, etc, and nothing seems to help. Even if the monitor is not connected in anyway to the radio, ie; used with a different computer in the shack, it still causes interference. On thing to note is that this monitor uses a laptop type power supply while my other two monitors run off regular 120v. Not sure if that makes an difference as I use a laptop ?and it works with causing no such interference problems.?I would appreciate any additional ideas to try and solve the problem. ??To save bandwidth here, please respond off line.
