Hello all,
I bought a new sleeping bag, bag liner and air mattress for this one!
John, NU3E, and myself, WA3WSJ, will hike in 5.5 miles on the AT to
Eagles Nest Shelter, PA late Saturday morning. We will then setup camp
at the shelter.
Look for us on the air Saturday late morning until Sunday
Bill,
Thanks for the feedback. I'll add it to my filter
setting database. I've been meaning to get to setting
the filters, but it's been just one maddeningly,
mundane thing after another that keeps me from getting
to it. This weekend FOR SURE, no matter what (short of
Nuclear War).
Just as
I would like to make contact with any builders who are currently putting
together the above combination, or any builders who have recently built such
a combination.
Thanks in advance,

Could someone help clear something up for me?
Are there any band choices on the KFL1-2 that are not compatible with
each other? I can't find anything in the documentation that says
otherwise. On my last K1, I had 40 and 80 meters on the same board.
It worked fine and I had no problems. Now
In doing BFO Test (pg62) my BFO Low Freq. is 4912..87. The manual says it
should be less than 4912.7. Will this cause a problem? The BFO range from high
to low is 4.39kHz

Problem solved. I am feeling a little stupid at the moment. I had the same
issue with another K2 that I built some time ago but forgot the solution. I
fixed the problem by adding a 2pf cap from the junction of X3, X4 and L33 to
ground. My brain must be going.

That information source is incorrect.
The 2 band boards can be built for any 2 bands.
The 4 band boards OTOH, share components between 2 adjacent bands, so only
40/30 meters and 20/(17 or 15) meters may be used on the 4 band board. Yes,
either of the band pairs on the 4 band board could be

Thanks for confirming my initial thoughts.

Only on the four-band KFL1-4 board is there a strict limitation to the
allowable band combinations to 40m/30m/20m/15m due to the cutoff
frequencies of the elliptical low pass filters on the board.
I should have stated the actual allowable band combinations for the KFL1-4 as:

produce a shifting RF output or FSK. Today, those

Any idea when they will have a solution in place that doesn't involve

All it requires is diagonal cutting pliers, the same as you use on
resistor leads, etc. in kit construction. It is not necessary to file,
grind, lap, etc the pins.

You may be lucky and find that it's just the pins on the DSP module that need
shortening.
As to the availability of a DSP unit that has the right length

If you have binocular vision (both eyes work together and almost equal
corrected vision) I think you'll find an Optivisor to be superior to the
Mag Lamps. It is a headband with lenses that can be lowered over your
current eyeglasses. If you get about an 8 working distance,you can

I agree with the optivisor. I use it daily. And it fits over eyeglasses so
you can use it with them. The binocular vision and freedom from having to
put a big glass in between you and the work is wonderful.
I would be cautious of off brands. Sometimes they're good. Often not. One

Alright, a little bit of an update on my problem...
Gary at Elecraft gave me a list of voltages to check upon TX.
Unfortunately, my scope is old and I couldn't get it to play fair, so the only
thing I could really measure were DC voltages with my VOM. I'll probably go
ahead and start putting

Charles, N3EJS, was nice enough to point out to me that my strange resistor

pin 7 of the relays was probably shorting to ground.
Checking this, and Charles was right on the money (thanks,
Jeff,
You may be chasing a 'ghost' - in other words, that 'short' to ground may be
present at DC but not at RF.
Remember that the relays latch, and the armature will be connected to pin 7
for the band that has last been selected. Going further on that vein the
