Haven't really had time to use my K3 on 50MHz, but when I tried it
the sensitivity seemed quite a bit down on my K2/KXV50
combination. Unfortunately I have sold the KXV50, so I can't do an
A/B comparison.
Is this what the preamp is meant to address ?
The 6m preamp, when available, is meant to help in those cases where a
lower noise figure at the receiver input (or lower receiver temperature
if you prefer to think of it that way) coupled with the required
additional front end gain to provide that lower noise figure, would be
expected to provide improved receive performance as determined by the
station system design.
Your 6m receiving system may or may not benefit from this. It depends
entirely on your station's design and where the K3 as a component fits
into that design.
