I have a used K1-2 on the way, my first Elecraft rig, that is
currently configured for 40/20. Although two of these are my favorite
bands, a couple are missing and I'm having a tough time deciding what
to put under the hood as standard. At home, my single antenna is
optimized for 80M 40M and

From what I have read in the archives, you can put 80M on a 4-band
module but, because of component sharing, you'd loose the 4th band and
Not to burst anyone's bubble but please keep in mind that Propagation the
past two days have been above normal. In fact they were excellent. This is
very much a Big factor.
And when the propagation returns to normal the next few days the amp will go
on to overcome
the absorption losses.

Good propagation most certainly is a big factor in QRP DX work, John,
but I feel you may have missed my point.
Assuming poor propagation, if I make a QRP contact 600 miles away with a
decent antenna, and my buddy across town with the same power and a dinky
wire hanging out the window does

Possible band combos on KFL1-4:
40-m, 30-m, 20-m, 17-m
40-m, 30-m, 20-m, 15-m
Add the following: 40m, 30m, 17m, 15m.
30-m, 20-m, 17-m, 15-m
80-m, 30-m, 20-m
I don't think those two are good combos without some filter redesign to allow
20m and 30m to share the same low pass filter

Yea, I hear you. You'd think 20 meters is the band nobody would skip
but, I find I use other bands more. 20 Meters is where the big guns
seem to
It's all smoke and mirrors.
Don't believe that myth about 20 meters for big guns.
We QRP'ers have equal share of the fun!
Their sigs and ours is fair game because propagation is King.
I've heard QRO stations in the noise too. Amazing!
see you on the airwaves!

Not really, but I am trying to avoid the big contests when all the
kilowatt klowns come out of the woodwork. I love the QRP contests and
various QRP fox hunts.
Mike, thanks for the comments. But I am still a bit confused.
Would an 80/40/30 combo work on a KFL1-4 board?
Thanks

Another option I am thinking about is multiple 2-band boards. Keep
the 40/20 and add a 40/30 and an 80/40. This way, I will have my
primary band, 40M, available at all times and switch in 20, 30, or 80
as the need or propogation warrants.

You could build a KFL1-4 board mostly normally per directions, with band 1
being 40m and band 2 being 30m, and both using the current LP and bandpass
filter designs. After that, you could build band 3 as an 80m band, using the

Sheesh, I can't win for losing on this. Heh.
I am using the K2/100 KAT100 combination into a Carolina Windom 80. It works
well on all bands (excluding 160). On 30 meters the KAT100 SWR seems to
occasionally fluctuate wildly as indicated by the LEDs. The leftmost LED is
always (stays) lit with power applied even during the fluctuations.

Getting an effective RF ground at the higher frequencies isn't really
difficult, but it sometimes takes thinking about it a little differently.
The problem is that wires going to an earth ground are usually quite long in
terms of wavelength. That makes them ineffective.
For example, you have a

Check the number of red wire turns on T5 - count the wire as it goes
threough the center of the core - counting only the outside turns can
produce a numer that is one turn less than the proper number. This sounds
like the sitation that occurs when there is one extra turn on T5.
