[Elecraft] K4 split audio

[Douglas Speer]

Just got my K4 back from Elecraft after having the tip of my Paddle plug breaking off inside the socket. So I’ll just now learning the rig.  

Question on audio adjustments while operating split. Is there a menu I have not found that will allow adjusting audio gain separately for the main and sub receivers?  When DXing, I find with both set at the same level that the loud pileups is overwhelming while trying to simultaneously listen for a weak DX station.
