I think you will be impressed with the diversity performance of the  
K3, to me it was well worth the investment. Just using my available  
antennas being very close to each other I have noticed a big different  
receiving DX signals with QSB on 160 meter.

Here is a recording of 4X4DK calling using diversity. Every time the  
signals tilts over to one side, the signal has dropped out of the  
other which proves that two antennas are better than one. Another  
thing worth notning is that the static discharges you hear in the  
beginning of the call is stronger in antenna than the other, so not  
only wanted signals are improved but diversity can also help fighting  
QRN depending on its nature.

If I remember correct, the left channel is an East pointing pennant  
and the right channel is a 20 ft coax loop.

I wish I hade more recordings at hand, but I am sure others have and  
can chime in.
