[Elecraft] K3s Line Out (stereo)

[Bob McGraw K4TAX]

I agree but in the case of using two radios, two pair of headphones, a 
switching system and getting hum indicates a serious deficiency in the 
station interconnection and ground scheme. Everything should be at the 
same potential, thus no current would flow.   As they say "sum-tin not 
right".
