Hello.
In checking voltages in my K2, I find that the voltages on U8 pins 10 11 are
reversed. Therefore the U7 pins 5 6 are reversed. I get 5 v where I should
see 0 v. Also on pin 24 U6 i measure 0volt unless I have the CAL FCTR mode
activated. I think I had this problem once before but
Earl,
I assume (sometimes a bad thing) that you are referring to U6, U76 and U8 on
the Control Board - you did not state which board, but the RF Board U8 is a
voltage regulator and has only 3 pins!
This is a case of observing digital signals and the level depends on just
how the K2 menu is set
I think I have to some calibration because I only get 85w out on the kpa-100.
No worries. I read this is easily fixed.
However I notice my power output fluctuations between 17 and 22 watts with the
tune button. It clearly goes up and down in a tick-tock fashion.
Can anyone exlain why this
PRICE REDUCED AGAIN!
This is as low as it gets! If it doesn't move this time, I'll try other
venues.
I've decided that I want to explore the possibilities of Software Defined
Radio. In order to do that I must sell one of my K2s. This is a serial 37xx
vintage K2 and has been upgraded to the
David,
This question comes up from time to time, so let me attempt a long
explaination for general information of those interested.
The power control for the K2 is speced at 10%, and you are seeing a +2 watt
and -2 watt variation at the 20 watt level, so it does fall within spec
limits.
The
I still think there are some oddities (firmware bug?) in the K2 ALC algorithm.
I still haven't figured out why I sometimes get 170W out on 160m.

Thorsten,
If I recall your original description, that high power glitch is a result of
the 'attack time' delay in the power control circuits.
Yes, I do believe there is a firmware oversight - the power leveling
controls must change (to compensate for the gain variations) when switching
from band
Hi all. I just did the transmit testing for 40m in the third testing
stage on the RF board this morning. However, I ran into some odd
things. At 5 watts, the K2's meter reads 6 watts and the current used
is about 0.06 amps high. That didn't seem too bad (something to look
into) so I kept

it went together smoothly, the problems was some distortion caused by the
built in speaker. Bending the frame slightly solved the problem for now.
Just received a replacement speaker thanks to Elecraft customer service

The alternative is to always reset the power drive to a very low setting
when changing bands and build up to the requested setting in a few dot times
of power output. I believe some of the past firmware releases actually did
it that way.

The K2 has been sold. Many thanks...

John,
The VCO frequency of 8903 kHz is not correct for the 40 meter band.
I would be willing to wager that you have installed the 'Rework Eliminators'
which includes the changes to the RF Board for the K60XV.
The K2 manual clearly states that one should NOT install the K60XV
components until

This is why you need to get a Weller WTCPT which still uses real
copper, iron-clad tips and is made in the USA. I swear by my Weller,
life is too short for junky irons! 73 de Alex NS6Y.

I use a METCAL soldering station and a METCAL Desoldering station. This
is a real high end and expensive set-up and not for everyone.
Weller is good but not made in the USA. At least not anymore.
Components are made in China and Mexico like everything else.
Get whatever you are comfortable
Hi,
I very confused, I'm trying to connect my Yaesu MD-200A8X mic to my K2.
I changed all wiring of the Yaesu mic to match my other Kenwood mic. I
don't want to change jumper block on the control panel... and the Yaesu
mic will be used exclusively on my K2 now but for outdoor operation,
I met two Metcal engineers (retired) at the SVARO.org swap meet and they
showed me a lot. They said they operate on 13.52MHz. They will go
through a solder ingot one minute and solder SMT's the next. They said
early models had no SWR foldback and they added 2 zeners for
protection. Also
I'm glad you brought that up since I love the Metcal. You can get
decent Metcal stuff on Ebay. If I had to choose one iron, and I did,
since I had a Metcal too, I'd choose my Weller. There's another
brand, Japanese, called Hakko and imitators of the Weller stuff but
that's ok they're good.
I found it !!! For a reason that I cannot explain I put earlier on
the control board a jumper over FUNC on P1 header and should not be
there. Now, everything works fine. With my Kenwood MC-43 mic... no
problem... but with Yasesu mic, it was affected by this jumper. Anyway,
no extra
I agee with these comments. Weller has a good reputation but is also a very
high end product price wise here in Hong Kong. Hakko, Goot, though 'made in
Japan' are similar and also made with outsourced parts and probbaly labour. A
Hakko 936 runs about $150 and a Hakko 808 desoldering gun around
