[Elecraft] KX3 as a base station? Yes, because it's all relative

Excellent. I've done my own TX phase noise plots, and I can assure you  
that the KX3 is very clean. You can also read past postings from those  
using it at field day, etc.

Our original group of K3 field testers includes several who are line  
of sight with each other in the Santa Cruz mountains. They have also  
been evaluating the KX3. They have had no problem with wideband  
spectral noise.
