Dear Gang:
I can no longer work up on my small tower, and need to find someone who does

I assume RF power level settings for the KXPA100 and K3 are the same?
I had similar issues with the Powerwerx, but it occurs only with loads above 15
amps for any length of time. The fan noise was so loud it was annoying. With
some age on the supply it's much worse. I swapped to an Astron
I suggest taking the lid off of the power supply and inspecting the fan for
