[Elecraft] K3: listening to both rcvrs

[Joe Subich, W4TV]

If you must pollute the audio from one receiver with audio 
from the other receiver, add a 5 to 10K pot between the tip 
and the ring of your headphones and adjust it for the level 
of pollution you need.  

There is no need for Wayne (or probably Lyle) to design 
crosstalk into the DSP process.
