A clue..... at 500 watts with the KPA500 there is an issue. At 50 watts
using just the K3 there is no reported issue. What's the difference?
RF field strength. Sounds like it might be and RFI issue.
Check all PL-259's and make sure they are VERY TIGHT. Check jumper
cables, between each piece of equipment and make sure they are in good
condition and connectors are properly attached and installed. If in
doubt, replace them.

I have not looked at the video but this sounds very similar to a problem I have
seen. In my case HDSDR sound output had spontaneously changed to TS-590 TX
CODEC creating a feedback loop through the PC. Break the loop and all is
normal.
