Check this out, and hope that you used some solder with Pb in it!

Guys - Let's kill this thread now. It was dealt with and explained more than
a day ago via private email between us and we're all happy :-)

Hello all
What I did was to stick one of those double sided foam pads about 1 inch
square and 1mm thick the type you stick posters up with onto the bottom cover
then all I did was remove the backing of the pad that would be in contact with
L33 and stick a cut square of black electrical tape o
i have experienced some whisker failures.
i have a bunch of printed info and articles on the subject.
Even some of the old Mil Spec parts 19500/35510 had tin plating.

I am not getting any significant signal input from the antenna and the loss

measuring 7.13 volts on the anode and 7.31 volts on the cathode. The manual
indicates they should be 8.0 and 7.5 volts respectively. On D7, I'm mea

Dave,
It would appear from those readings that either you have D6 or D7 installed
backwards or that both the 8R and 8T voltage lines are active, and they
should be mutually exclusive.
First check the diode orientation against the Parts Placement Diagram in the
rear of your manual, and if these ar

Thanks for the reply, Don.
D6 and D7 are oriented properly.
I am measuring 7.94 volts on the collector of Q1 and 7.15 volts on the
collector of Q2.
Anticipating your next question, on Q3 I am measuring: S=0 G=47mV D=51 mV.
D should be 8 volts according to the manual.
Tnx & 73,

I hereby proudly anounce, that all German manuals for the T1 are ready. Of
course the errata is included in the German REV A manual :-)
This manuals are real manuals not only a piece of paper with a translation
to be used with the original manual. The layout is 1:1 page compatible to

Dave,
You did anticipate my next question, and now I believe I can say that Q3 has
been somehow zapped since it appears to be conduction with a very low
voltage on the gate. Replace it with the 2N7000 that remains unmounted in
your K2 parts and request a replacement from Elecraft so you can fill

Thanks, Don. Your diagnosis was correct. Voltages are now right and the

I am building K2 04858 and have arrived at the display installation in the
front panel. I have a couple questions and am too impatient to wait for the
Elecraft gang to open up about noon [here] Monday so I turn to this group.

OK!
I'm new at this. Ignore my previous message! I did a search of this list and
found the answers:
Leave everything on the LED and LCD alone! Check for a clear protective
coating at time of mounting the circuit to the front panel, per manual.
Right?

Wayne,
If there are no stripes - REMOVE nothing from either the diffuser or the LCD
display. The white tape/paper never should come off the backlight assembly.
After you finish all the soldering, and before putting the front panel on,
remove the thin clear plastic film from the front of the LCD.
I have a new K1-4 S/N 1910 just built for another individual who
changed his mind. So now someone
has the opportunity to buy new, built and tested Elecraft K1 at a
tremendous savings.
It's set up for 40-30-20 and 15 meters with metal shaft vfo and about
170 Khz tuning range.

I have tried three batteries in mine and the yellow light always comes on.
My batteries were anywhere from 3.05 to 3.15 no load, but dropped to 2.
Just a question for the technically inclined group members:
How feasible or worth the effort, would be the addition of an option to the
K2 which would sample RF noise from a ferquency close to the used
band,(tunable?) which is devoid of signals, phase invert and reinject the
noise to an IF sta

Greetings everyone,
My 13-year-old son got his ticket last week (KE7DMK) and is quickly

practice with, but he is in need of paddles to use with it.
If you have an old and/or spare pair of paddles that you would part
