[Elecraft] K3: Audio Mixer

[David Gilbert]

There was a discussion here recently about being able to listen to the 
main receiver in both ears while listening to the subreceiver only in 
the right ear, which to me makes a lot of sense for contesting .... 
optimum spatial cognition using both ears to pick out weak callers on 
the main run frequency while being able to scan for other contacts with 
the right ear.

So I bought a Behringer Xenyx 502 audio mixer to give that a try.  It 
just arrived yesterday and I must say that it works great.  It was easy 
to set up and gives me total control over both audio channels ... I can 
make any amount of audio from either the main or subreceiver appear in 
either earphone.  Having the main in both ears and the sub in the right 
ear is very, very nice ;)   If anyone wants to give it a try, send me an 
email and I'll describe how I set up the connections.

The unit is about 7 inches by 5 inches so it doesn't take up too much 
room on the desk, and it's built like a tank.  A Google search will 
bring up several online sources, and they all seem to have the same 
price .... $45 plus shipping.  How they can sell the thing for that 
price is beyond me.

This would also nicely handle the needs of the upcoming SO4R DXpedition, 
although it requires it's own 120 VAC power supply and that might be 
inconvenient.
