HI Don and Petr,
Thanks for the offer Petr but Don has already been kind enough to send
me the Rev. D, 2000 K1 Manual. Thanks anyway!
I find it quite difficult sometimes to troubleshoot and follow the
schematics. Also doing signal tracing in the receiver and
transmitter is quite subjective using only an RF probe. It would be
better to have some RF values p-p so you could use
a oscilloscope and at the same time see the signal.
This is an older radio so I don't expect Elecraft to come up with some
new troubleshooting aids, but the K1 owners can
share experiences and test results.
I've just measured the resistance between J7-pin 6 to ground and it's 5.7K.
Please keep me in the loop. Thanks to both of you. Comments from other
k! owners are appreciated.
Thanks!

Hi Don and Bert,
as I noticed this evening > troubleshooting nor alignment parts are not same
in the different Rev. of K1 manuals.
Our sick K1 is also from 2000... RF board Rev. D, 2000 so I am using the
manual Revision D, Dec 1, 2000.
Unfortunately when I measured the resistances on page 45 (J7, J8 test
points) I found the J7 pin 6 has 5.6kOhms to GND but table on page 45 says
it should be >100k.
What makes me confusing is that when I opened the later manual Revision F,
January 24, 2002 I found that in the same table on page 45 the value of J7
pin 6 should be 5-7kOhms which souns ok compare to my measured value
5.6kOhms... ?!
Don can you let me know some hints what it could means in that case please?
The rest values are same in both tables and measured values are also
corresponding to it.
Bert I will send you the proper manual for your K1 (we have same Rev. ) >
Revision D, Dec 1, 2000 by email.
I got it from Don (many thanks Don!!)
Thanks for help in advance.
