I agree: The best lengths for a doublet are 44ft and 88ft and multiples
thereof. Have a look at Cebick's site. These lengths avoid nasty tuning
conditions which can create large voltages and inefficiencies in your
matching unit.

Joe,
Thanks for the very thoughtful analysis.
I'm very pleased to say that the problem seems to be greatly reduced with
the latest firmware (1.81/1.63). I can't tell if it is completely
eliminated, but it's certainly much reduced. Lyle, Wayne, what did you do?
Whatever it is, it seems to ha

I tried the K3 CW interface tonight and answered the CQ of CO6FU/QRP on
PSK31. It was very interesting to be able to hold a conversation with John

it really works.
I am glad that I read about sending dit-dit-dah-dah (IM)
I agree that corresponding with the end of the ALC bracket makes sense.
I remember looking at the pictures of the radio after it was mentioned
that the 6th bar was overdrive and I was thinking it odd that the

Why is it that when I tap the XFIL button on K3, doesn't it always go to the
next filter? For instance, if I turn the rig off and then back on, it just
continues to stay at FL1 when I push the XFIL button.
I I do anything with the config menu, then it seems to work...
Thanks,
John

Have you enabled either the 2.7 or 2.8 filter (whichever one you are using)
for CW and SSB transmit?

Here in the Northwest USA we already had summer. It was yesterday with
sunshine and temps near 70F.
Back to the wet stuff today.
The next sunspot peak will be a bit slower in coming but, hopefully, will

Cory,
The E42 error means there is something wrong with the VFO - most likely
a bad solder joint or an improperly tinned toroid lead. Check the
schematic to determine the components in the VFO and examine them
carefully, resoldering where necessary.
Once you find the problem source, I would

I had a K2 for a while, long story. It was the 10 watt version and I had
planned to connect it to my Ameritron ALS-500 which I run on my base
station. It needs only the "PTT" signal from the radio (available on most
radios) to go to transmit mode. I'm sure I could have found one on the K2.

At low power settings, does the actual power output go up to over 12 watts?
If so, the diodes in the KPA100 wattmeter have been damaged (likely by a

Replace D16 and D17 in the KPA100 and you should regain power control
for both high and lo ranges. To prevent

Hi elecrafters,
since this morning i have a problem with my KPA100. I cannot adjust t
rf output. In the high mode, i always have more than 100W with a
dummy load. In QRP mode, i can adjust .5 to 10w. When i reach the 10w,
the power goes directly (jumps) to the maximum power of about 100w.

Why do you want a bandwidth of 2.7khz then? Most of us would also find
listening to CW with that pitch impossible or annoying. You're missing the
point here. We open up bandwidth so we can hear things. I would hate to tune
around the band with a 400Hz filter.
The point here is, a 6kHz crys
Jerry,
T1 and T2 are not in the path for CW or TUNE, so they are not high on
the list of suspects for Lernart's situation.
OTOH, if the low power is on SSB (but CW and TUNE are good), then T1 and
T2 would be the prime suspects.

Lennart,
If you have transmit power problems in CW mode or TUNE, then the only
part of the SSB opyion board that could cause that condition is Q1, Q2,
Q3 and the associated components.
Look at the KSB2 board schematic near the bottom and you will see which
components need to be checked.

Dave,
Listening 6 kHz wide is fine if you listen up to 3 kHz UP AND DOWN your
frequency. (So you might have a station on zero beat freq, who cares)
Being an ex R/O used to listening on 500 kHz, this was normal operation.
