    Good morning My Good Brainiacs !!!! I just hooked up my new station with the DMU and a 20 inch monitor. Now I get noise on almost all frequencies until turn OFF the monitor. Is there an easy fix ? or should I move the monitor as far away from my tuner and rig as possible ? I do own a handfull of ferrites.:confused:

    It's worth trying clip-on ferrites on the monitor cable and maybe even the mains cable.

    I had a problem with one of my LED monitors. The wall wort was the problem, and not the monitor itself. Used and old linear supply to run the monitor and all is FB now. JB KB1YFD

    YOU WHERE RIGHT ON !!!!!!! I switched to the other side of my bench with NO improvement . So I started unplugging components . I found that my monitor cable was too short to move that far. Being 30 miles to town I chose to move it back to my right side of my bench . Then I unplugged the monitor power supply from my noise suppression power outlets where all my radio and other rig items are plugged,then plugged the monitor power into a simple wall socket by itself, and BINGO !!!!!!! NO HASH NOISE !!!!!! I AM ONE HAPPY RADIO CAMPER !!!!!!! cheers from whitefish montana !!!!73 too
