I am new to the Elecraft K2, I also have the same
problem except mine is reading up in frwquency
when I am tuned into 3.963.00 net my dial reading
is 3.963.21. I double check net frequency with
my ft 920 and they are dead on 3.963.00.
I need help where to begin looking!
Thanks Bill

I ordered my KAT500 and spoke with the designer there. It can go either under
or over the KPA500. If put over, the temperature of the KPA will run higher
so the KPA fan will run faster but still within tolerance.

Gil,
You will have to do CAL PLL and CAL FIL after properly setting the 4 MHz
reference oscillator Control Board C22. The magic is in setting C22
properly.
To accomplish that, go to my website www.w3fpr.com and follow the
instructions given in the K2 Dial Calibration article.

I can just recommend to follow Don's article. It has worked very well for me.
What has worked best for me was to use the N6KR method to calibrate the

Yes, you can use a component with a higher voltage rating. Before you buy
them I would
Ariel,
Electrically, you may always substitute a capacitor with a higher
voltage rating. Whether the larger physical size is OK or nor is a
different problem.

Hi John,
I can't duplicate that bug here. First try a parameter reset by holding the
MENU and powering up using the POWER key. If the problem is still present,
email me directly at pauls at elecraft dot com.

I see the same issue on my P3, but it only occurs if: 1- Span is selected
from the right column of buttons, and 2 - Span 200 is selected from FN8.
After that, selecting 10, 30, or 50, from FN2-4 results in a menu display of
100, 300, and 500, with an actual bandwidth display of 10, 30, and
Have you checked the connections of the KPA3 100w amplifier module. I have a
friend that was experiencing a similar issue, and discovered that the module
had become unseated somewhat causing intermittent RF power output issues. I
hope this helps.

Mario,
Look at the Control Board schematic in the lower right corner to see all
the components associated with U9 and check all of them for good
soldering. Also check P3 pins 7, 8, and 10.
RF board J8 pins 7, 8, and 10 are also in the path.
Be certain there is 12 volts at U9 pin 7.

Don,
Thanks for the reply,
I checked on P3 #7 and #8, both have 5V, #10 has close to nothing (1.4mV)

Are you counting properly? Pins 7, 8, and 10 are connected together
according to the schematic.
The pins on one side are numbered 1, 3, 5, 7, etc. while the pins on the
other side are even numbers 2, 4, 6, 8, etc.

Thanks for indicating the right order of the pins, I had measured the wrong
ones, rookie mistake I guess.
I just measured the voltage on J8 #7, #8 and #10, all have the same voltage,
5.2V.
I guess that's good, yes?

No, 5 volts there is not good at all. You should have zero volts DC,
but there may be some AC riding on that level. What is the voltage at
CB U9 pin 6?
I am thinking that either you have a solder bridge or you have a shorted
C29.

Yes, U9 pin 6 can have 6.5 volts, but...
There is capacitor C29 between U9 pin 6 and the AF OUT signal (and the
headphone jack) that should block any DC. If you have 5 volts at the AF
OUT signal (P3 pins 7, 8 and 10), then that is a problem.
You have something shorted to another signal

I have s/n 3012, factory built. On a few occassions I have been told by a QSO

to check against WWV.
Three questions:
1) is comparing to WWV a good method to confirm display accuracy? I used my P3

Jack,
Check page 50 of the manual. I suggest using Method 2. Use the highest
frequency WWV that you can reliably receive, and make certain you are
zero beating with the carrier instead of one of the transmitted tones.

Hi, Jim
In your K Line configuration the cabling I would suggest is a 15 pin Accessory
cable between K3 and KAT500 and another from KAT500 to KPA500. In that cable
are four band lines, AUXBUS, and amplifier key line. Both the KAT500 and
KPA500 can connect via serial port connections to a PC
I use a program called Spectran ( freeware ) which will display the audio
frequency of the output of the K3
I set the Frequency of the K3 to .000 kc (usb) this will produce a
1kc tone to the sound card in the computer when tuned to WWV at 10 mhz
Spectran will then display the frequency
Just another note:My K3 will not produce a audio tone below 200 cycles in
the speaker.. ( could be my ears) so finding a zero beat is impossible as I
could be off that much above or below WWV trying to callibrate that way.
