Hello,
Use a lighted match stick or cigarette lighter to burn away the
enamel(carefully), then use fine sand paper, and Surgical Spirit on a
cloth to clean away the dirt.
Solder wire should have special flux to capture the rest of the dirt
to make tinning easier.
You will find that the
The wire used for these toroids is I believe in the category of self fluxing
meaning it is designed to dissolve in the presence of the high temperature of
molten solder. It is microscopically thin and the quantity that we work on per
hour is very small compared to an industrial set up where

I found the blob method worked very well for me. After awhile, it was just
natural. The key is to have a clean solder tip in the beginningand make
sure you clean it afterwards once the blob has done it's job. Another key is
to turn the heat up on the solder pencil to make sure you have

Hi all!
I just finished building my front panel and had some problems with
the resistance checks. On J1 pin 1 through pin 7, also pins 13 14
the meter registers absolutely nothing. All of the rest of them are
just fine.
Anyone have any suggestions??
Thanks,

Kristina,
You didn't mention if your building a K1 or K2.
Before you drive yourself nuts, remember that no meter reading is infinity
which is greater than 100k (K1) or 1 meg (K2).
Good luck with your kit.

Thanks for following my saga. What other rig manufacturer would do this and
encourage it. Sure makes me glad I chose a K2.
I agree that this mod makes no real performance difference, but just suits a
few of us who tend to do things different from most. Plus playing around with

I am curious about doing this sidetone mod on a K2 rev B. Elecraft changed the
sidetone circuit from serial number 3000 on, and wonder how effective the
sidetone mod is on a rev B K2. My K2 is serial # 5093.
The mod is described at

The N-GEN also worked as designed when I connected it
to my Ten-Tec Argo 556 QRP xceiver. I am now considering
the elecraft W1 or XG2 mini-mods for next month. I should be

After having re-done many toroids, I have to agree with Lee. I was my
own worse enemy. The more you do it the easier it gets. It is
important to have a flat (chisel) bit on the soldering iron, as it holds
the blob better. I have 12 more toroids left to do to finish up my K2.
