[Elecraft] KXB30 sensitivity better than KXB3080?

Martin,

I would be hesitant to make comparisons based on signals on the air. 
The signal propagation can make a big difference.

If you have a signal generator that will produce a measurable (and 
repeatable output, that can be used for a valid comparison.

Normally, the 30 meter signals are as good or better with the 3080 
option as they were with the 30 meter option.  You may have a problem, 
but first try adjusting the 30 meter trimmers.  For accuracy in 
adjustment, they must be adjusted with an insulated screwdriver blade - 
even a metallic screwdriver wrapped with tape will cause some de-tuning 
during adjustment and you must find the proper tuning point by trial and 
error.
