You can see the enamel burn off, and the solder tin the copper.
Just make sure the iron is hot enough, and you take your time.

Hi,
This devil has many appearances and uses different names depending on the
person in doubt. Several of the names are: Icom, Yeasu Kenwood, etc.
It isn't that difficult.
Put the part of the wire to be stripped flat on the surface of the edge of a
table. Take a real sharp knife and scratch with

Not to worry, the enamel itself will not adhere to the solder at all, so if
you have the leads with a nice shiny tinned surface, you can know that they
have been stripped as well.
As for zapping ICs, practice safe ESD techniques at the workbench. If you
have a wrist strap available, use it

Hi Lee,
I had the same reservations, vis a vis, winding the toroids, and the advice
you have received is spot on.
There is an additional solution, however, and that is to purchase a complete

Anyone using a MicroHam microkeyer with a K2 with an outboard KPA100 ?

the device makes no connection to the K2 thru the K2's serial port, whether

Most multimeters, when used for AC measurements, do in fact read RMS values.
Specialized meters do exist which will read peak (or average, or whatever),
but the common meters do read RMS only. If you measure your household AC

I am at the stage in assembling my KX1 where you check the resistance

All of the other resistance checks are correct and everything else seems

Lee,
After you've installed a toroid, check the resistance across the toroid leads
(all pairs if it's a transformer) at the solder pads. If it's zero, you can
be assured you stripped the leads properly and got a good solder joint on the
board. Since I started doing that, I've never had a bad

Fred,
The 'L' or 'U' in the K2 display will blink if you have VOX enabled. Press
the MODE/VOX button until it says 'Ptt' and the blinking should stop.

If you don't choose to buy Mychael's pre-wound toroids (which I did for
the K2 RF board) you might want also to try these two hints:
1. Make sure to wind the toroid the right way, with the top wire being
on the correct left/right side of the bottom wire. Elecraft's manuals
