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.

Hi,
I wonder if anyone else has an observation about the sensitivity of
the KX1 on 30m with the original 30m board compared to the 30 & 80m
board? I've noticed that signals are not as strong on 30m now with
the new board. For example, the RTTY station on 10100kHz is at best a
4x5 whereas it used to be 5x9. I can only hear the strongest CW
stations.
20m & 40m are as good as before.
