These S-meter settings sound like the readings when T7 is reversed. I have
seen this several times and it makes the AGC and S-meter flaky as well as
the sensitivity low. However you can make the radio appear to work although
it just seems not quite right. The red wire winding should be

Just wanted to let everyone know that thanks to Don's helpful hints,
the problem has been found (yours truly forgot to install a couple of

Hi Bob,
You hit on a disappointment of mine - the K2 does not have true QSK. If it
did I would have had a second K2 here. To date I haven't heard of anything
that can be done to get QSK like some of the other rigs. When I am Cqing I
don't need QSK. Actually your ears get a break when running

Bob, Tony qnd all,
Have you tried setting the menu item 'T-R Hold' to 0.00 or 0.01? The
firmware defaults this setting to 0.05.
If my dot time calculation is anywhere close, a setting of 0.00 should allow
you to hear between dits up to about 60 wpm. With a setting of 0.05, you

Congratulations to N6VX for working 3Y0X with WA8KNE's KX1. I guess I'm not a

for a QRP contact. I have completed WAC on 40m with my KX1,
Thanks for all the comments guys. I may have unrealistically rosy memories
of using Ten Tec gear but as I recall the QSK sounded very little from the
sidetone when not transmitting - and I guess my definition of true QSK is
just that. By the way, my T-R was set to 0.01 - it was better on the ears
Thanks for the info about the KX1's performance on 30m without the 30m

The KX1 will transmit on 30 m without the 30-m module because the

hi all,
I am working on the RF board, page 65 where a lot of capacitors are to do.
The first problem I had was C22 (3.3pF), which I could not find. I found a
capacitor with 2.2 on it, which I used after reading the parts list, but
now I am at C33, which should also be 2.2 but nothing around.
Hello all,
I have discovered that the 20 and 17 meter ouput power of my K2/100 is running
around 65-70 watts maximum. The other bands all put out the normal 100 watts.
(85-90 watts on 10 meters.) When you try to go up to the 70-100 watt level on
20 or 17 meters the K2 flashes a Hi-Currect

Study page 1 of the K2 RF Board Parts List. It appears to me that the

good light and magnifying glass. This I remember very well as it took
several hours to find.)
Hi
If you will check the parts list I think you will find the 2.7 pf caps are
alternates for the 3.3. These are the blue caps marked 2.7c. You should not
use the 2.2 brown cap in this place. this is for c33.

This is for anyone who may be following my previous

measurements, and I am getting the following KIO2

Dave,
Yes, you can use that stereo cable - with some reservations, and as long as
you understand those reservations, things will be OK.
First thing is that if you use the external speaker jack, the ring contact
will be shorted to the sleeve, so only one channel (usually the left) will
work.
Hi Dave:
One more thing... don't sweat the possible roll-off from the PHONES
jack. It's minimal and should NOT compromise your adjustments one
whit. But DO be sure to set any AF filtering (KAF2 or KDSP2) to OFF
or to its broadest setting.
AGC can be set to either ON or OFF... doesn't really
