[Elecraft] In praise of the sub Rx & Diversity - Addendum

[Don Wilhelm]

Drew,

True diversity reception requires 2 receivers which are locked together 
in not only frequency, but also in phase.
The KRX3 receiver is of the same design and implementation as the main 
receiver, making diversity reception possible.

The antennas must be different, one horizontal and the other vertical as 
one example although other combinations are possible - not only 
differing polarization but oriented in different directions.

The result is that an "option board" for one receiver will not create 
the conditions necessary for diversity receive - two receivers can 
produce that result.

73,
