[Elecraft] Diversity reception with two linked K3s

[Jerry Flanders]

 From what I have read in years past, I agree locking the two 
together could probably be useful. I don't know enough about it yet 
to be sure of this, though - having each radio in a separate earphone 
may be all one needs unless beam-forming is a goal. In time we will 
see how the subreceiver is locked to the main and then we should be 
able to duplicate the KRX3 performance. One step at a time.

In the meantime, I have enjoying the several hours I have spent 
listening. I now have the two reference oscillators in agreement so I 
don't get the beat I heard earlier. Using one vertical antenna and 
one horizontal last night I observed polarity differences on 75 M. 
Also some sort of spatial effects on 30 M.

It is definitely not a $2500 solution to a $600 problem - it is 
actually a zero-cost second receiver solution for the guy who bought 
two K3s for contesting and sees the second one just sitting there 
when not contesting...
