Subject: [Elecraft] K2 receiver problem
Hi list,
got a K2 from another OM on my workbench. It's got a
Hi all!
I´ve just finished installation of the KNB2 into my K2. When tapping
the NB-button on the K2, the display shows Not Inst. I have
re-examined the KNB2 board. U3 is installed/soldered correctly and as
far as I can see no other components are installed incorrectly or
backwards. I have also
Hans,
The Not Inst message means only one thing - the KNB2 is not communicating
with the K2 MCU. That comunication occurs over the Auxbus line. That
signal is present at pin 7 of the KNB2 connector.
I suggest that you check for continuity (and shorts) from the K2 Control
board MCU pin 40 to
First I must emphasise that I am *not* an Elecraft junky - junkies check
Elecraft's web page when asked by the XYL for a new washing machine 'just in
case'. But I have just finished the KX-1 and am *more* than impressed. And I
really enjoyed building it (no smoke, flames or burnt fingers).
Happiness is a K2 on 40M CW!
Thanks for sharing Steve!

Gerhardt,
It sounds like the AGC Threshold is not set properly.
I would proceed by first checking the alignment of the bandpass filters in
Transmit mode (at 2 watts) and then set the AGC Threshold for optimum
receiver sensitivity - with no antenna connected and AF and RF Gains set to
max, adjust
You need both, Simon... I could not sleep at night
till I got both!!

Hello Gerhard,
First, do the AGC threshold adjustment (instructions located at end of
Assembly, Part I in the manual)
Then do the S-Meter Alignment, the instructions of which follow the AGC
threshold adjustment instructions.
It sounds like the AGC is set a bit too aggressively at the

I attempted to send the following message to the Elecraft list in response to a

Hi John,
No, you are not being moderated. :-) We frequently do not reply to list
list owner emails for 24 hours or more.
What was the content of the reject message? Can you forward it to me?
It likely was an automatic reject from the qth.net server thinking your
email server is sending
Although I never did hear from Brian, my query to Eric, which I also addressed
to the list, apparently made it, so it was a temporary thing. Not sure why, but
remember, just because you're paranoid doesn't mean they're NOT out to get you. :-)
Anyway, Cliff's question did get answered.

Hi fellows. Can't manage to communicate between computer and K2.
Through control program or HyperTerminal verified that serial port is
functional on the computer ( Win XP ).
Can hear Q1s signal loud.
Here are some voltage measurements made this morning.
U1-1 14.12
First I must emphasize that I am *not* an Elecraft junky.
That's how it starts. I built the KX1 first and then the K2 and then the K1.
Soon I looked around at all the other test gear that I bought from Elecraft
and now I'm not too sure how much gear you can buy before qualifying as an

The replies are flooding in (mainly private mail), so far the advice is
split evenly between:
[1] Yes,
[2] No,
[3] Therapy will not help.
So do I build a K1 over the Christmas holidays or write more software?
Or save my money for the K3 (DC to daylight)?

Gil,
Yes, first concentrate on the low voltage at U1 pin 8 - be sure diodes D1,
D2 and D3 are oriented properly and capacitor C8 is correctly 10 uf and
properly soldered. If that does not bring the voltage up to somewhere
between -6 and -12 volts, look at the oscillator components connected to
You've given generously of your time writing software.
Have a break and do something for yourself. Smell the flux and build a
radio.

Well, the selfish answer is that you should write code, which would
benefit all of us ;-) But considering the season, I think we should all
give you the gift of time to relax and build a K1.

Over the past month or so, I've been taking
my K2 (#4119) to a remote mountaintop cabin for
RR with my XYL. This location is quite remote
and previous visits seemed to be very RFI-quiet on
the other bands, so I decided to install a Beverage
on October 12 and try listening on 160. It is
Might there be a short on the output of U1 pin 5? This is a TX output
from the driver chip, and even with the negative supply being low, it
should not be that close to zero, especially with the input at the
high rail. I would suggest looking for a short across C3, L2 to
ground, or even
I can quit any time -- I just don't want to.

Bill,
Congratulations on getting the beverage installed - I want to try one here
myself, but I will have to keep the length to less than 500 feet if I point
it toward Europe - that 800 ft beverage should hear quite well.
If I were in your shoes, my first attempt would be to put a parallel tuned

Yep, it turned out to be a short that was pulling J1-2 to ground.
