[Elecraft] K3 RF Feedback Problem

[hb9brj]

I had an RF feedback problem when transmitting in digimodes (TX audio via
LINE IN).
On some bands and at power levels above 20W, my TX audio was distorted.
BTW, my previous TRX did not show this problem in the very same setup.

Similar to MIC, also LINE IN has an RFC in its GND line (L5 on the KIO3
Audio IO board).
After removing it and placing a jumper, my problem was gone!
