Wes,
While I think the K1 (4-band especially!) is a
fine rig, it's luster for me was dulled a bit when
I was able to make a KX3 my primary QRP rig.
Pluses include:
* Way more than four bands
* All modes on the bands in does cover, even
digital as an option
* Superior receiver
* Panadapter available
* And others too numerous to mention here
all in a package that is not really all that much
bigger than the K1.
Two definite pluses of the K1: I enjoyed building
it more (a melt-solder kit) and it has a bigger
speaker.
After considerable thought, I recently sold my
fully-configured and updated K1 #18. I sort of
miss it, but how many rigs can a body use?

Hi all,
The KFL1-4 module needs trimmers that are both
wide range and extremely temperature stable,
due to the high loaded Q of the band-pass
filters. To emulate this stable capacitance
with trimmers now available, you'd have to use
a hand-selected C0G cap in parallel with a much
smaller trimmer for each of the original 16
trimmers. This would be extremely tedious for
builders. So, while it is possible, it is not
practical.
