[Elecraft] Solution to Low Volume on Right Side using Sub receive on KX3

[Bob Stephens]

The SUB receive on the KX3 is great for working pile-ups.  The issue I have is when the DX station is weak, turning up the audio volume to hear the DX makes the pile-up so loud I can't hear the DX.  Anyone know of a simple solution to making the pile-up audio lower and DX louder other than an audio mixer?
