My best wishes to everyone on the reflector. I started building my K2 a
month ago and it reminds me of the days when almost everyone had build
their equipment and every ham was a mentor. Over the years I have
enjoyed the increased access that the internet gave us but got a little
jaded when
Hi,
I am just at the first alignment and test stage of my K2. Everything
checked out just fine except the step where I am to adjust R1 on the
control board for 3.80 v on pin 5 of U2. The highest I can get the
voltage to go is 3.38v. Is this something to worry about? If so, any
clues?
Hi all,
I have been through the archives so I know this has been asked and
answered a few times but I still am not making much progress on this.
The problem is that my resistance test for Q7 collecter is not correct.
With the common probe on ground and the positive probe of my DVM
measuring
I am progressing through debugging the bad resistance reading between
ground and the collector of Q7 on the RF board. I have it up to 900
ohms now. The manual says '500' is a passing resistance. What is
'normal'? Is 900 ohms a sign that all is well?

Its an obvious direction that 2 K2s (KK4?) would be a great,
desktop-friendly SO2R setup. Anyone with recommendations on the best
way to do this (or to simulate the 2 RX/1TX capability of the 7800,
Orion, FTDX9000)?

Well, just in case anyone searching the archives for hints on a similar
situation, I had a solder bridge on the top of the RF board between the
case of Q5 and the lead from R44 that fed from the bottom, just
impossible to see without magnification, etc. Probably no one will
make the same
I am just at the 40m L1/2 alignment for my K2.
On rx with the lcd set at nite, I show 13.6v @ .18a.
Using an external analog wattmeter into a dummy load, I measure at 5
watts 12.9v and 1.8a. Also, the display shows the power output at 3.5w
instead of 5. When I tune the power output control so
Hi all,
The symptom of my problem is:
1. when setting k2 power to 5 watts, I get a reading of 2.2 amps with
abt 0.8v drop
2. when looking at power output with an external wattmeter, 5 watts
reflecting on the external wattmeter shows as 3.8 on the k2. Similarly,
10 watts on external wattmeter
The good news is that I did a diode dance, had the rf probe diode in
D9, had the real d9 substituted for a 4148 and a 4148 in the rf probe.
Will swap them around and redo the tests!

Second qso with HZ1EX on second call!
I am so excited to see this amazing little box go live!
Thanks so much to the reflector for help around the rough bits. Also
thanks to Scott for continuing to send me the parts I lost!

Hi all,
I am trying to install the KSBS2 into my K2.
Problem symptoms are that I get the Hi Current warning, plus I get no
variance on my separate receiver when trying the fine balancing.
The rest of the alignment went okay, SSBA on BAL gave me good nulls
with tweaking R1 both on USB and
Hi all,
Thanks for giving some ideas!
I checked the resistors on the bottom of the ssb board, they are all
correct. I must say that trying to identify parts on the top of the
board is a real challenge, its so stuffed that its almost impossible!
Don, I redid the output amperage at 10 watts:
Being one of those clogging the reflector recently with cries of help,
let me put it in context.
In building the base kit I experienced only 3 problems:
I had a poor solder joint that kept me from getting the right AGC
voltage but the troubleshooting guide led me to it almost immediately.
The
I assembled my kpa100 during the week, what a nice experience!
The functional operation of it is fine, aligned well, tx audio is good,
temp, etc. all fine.
The problem I am experiencing is with the audio.
If I plug the audio cable only into the k2, audio is as good as the
original. But if I
The Anderson Power plug on my KPA100 has some play in it and when it
moves slightly, power drops. Has anyone seen this before and what can I
do to make it stable?

Hi,
I cannot get the initializing led to flicker on my kdsp2. When I do the
voltage checks, I really cannot make sense of it, versus the schematic.
I have double checked that the right parts are installed in the proper
orientation, re-checked for bridges, etc. I have checked that none of
Thanks Lyle,
Its not RTC is just dashes and any AFIL setting is 'not installed' so I
will check point 6.
I will let you know!

I have seen the 'cheat sheet' that was graciously posted on the
elecraft website but has anyone ever built an operators manual for the
K2?
It would have the setup and operating sections of the K2, KPA100 and
all of the modules. Today I have to look through a bunch of things
(although its
Go to google and do a search for Spectrogram. I found the free version
on some German site and it matches the version that is used in the
instructions on the Elecraft web site. The new version I could not
figure out!
