It's only an advantage when you're trying to ward off a key clicking
neighbor. If your potential neighbors would have non-clicking rigs, there
is no advantage. In any case, you are just being a jerk (or worse) if
you're knowingly producing key clicks.

How could a 2 circuit plug be mono since there is only 1 circuit?

Benny,
Well, if all that is OK, then it should work unless there is a problem
with Q24. Check the value of C169 as well as C173 and C174.
It is particularly worrysome that you are seeing something around 8 MHz
at pin 6 of U11. Please tell us how you are measuring that frequency
('scope or
If you get listening to a stretch of it to see how much flat beat
time you get, that's as close as you'll ever get it. Plenty close for
me and then some. 73 Guy.

Thanks, guys - that works FB, and my K3 appears to be right
Benny,
Additional thoughts - check D38 for correct orientation.
Try putting a jumper from the junction on L33, X3 and X4 to see if you
get oscillation at 4915 kHz or something close to that frequency - if
you do, the crystals are OK and your problem is with L33, D37, C169 or Q24.

I will do the tests tomorrow, but one question:
A jumper from junction of l33,x3 and x4 to where?

Before I purchased my KX1, I recall reading something about a 3rd party
product offering for a zero beat mod.
Predictably, I can't find it in the Elecraft Archives or by Googling
KX1 modifications.
Any KX1 users out there know anything about this mod?
I was quite successful in the recent CQ
Search for K6XX CW tuning indicator. There is a kit for the K1, KX1, and K2.

Having received new micro LEDs for my button kit (dang those things
are ity bity), I'll be installing one in my K1 this weekend.

Stan,
You can thank Tom Hammond N0SS for developing the circuit board and the
initial kits from the initial K6XX design. Yes, Tom does not take
enough credit for himself, and he put a lot into that mod kit - see his
website at www.noss.net.
The kits are now available from N3EPA
Sorry for the Typo, Tom's website is www.n0ss.net - I put an o in
the address instead of a zero - I will blame it on fat fingers
