I use a low cost earth mat and wrist strap. In order to connect them
together (and to earth) I have an aluminium bar alongside the work
bench, this in turn connects via a length of "hook up" wire and
crocodile clip to the station ground. At the start of each session I

Hello Dave and all,
I have and old mat with a wrist strap attachment, meant to be used
with a keyboard. I don't like wrist straps, so I use a piece of 1"
square pcb board and tuck it next to my skin, under my belt. This
frees up my hand.
This square of pcb board is grounded through it's coily
Hello,
Look for me between 14:00 and 16:00 UTC on 40, 30 or 20 meters.
I will be out on the Appalachian Trail to make a few QSO.
Also look for me next Sunday in the Flight of the Bumblebees Sprint out on
the AT, BB #17.

Hi, folks,
Well, I've let my SSB kit for my K2 sit long enough. However, I had to look
all over for it and when I found it, I couldn't find the instructions.
Went to the Elecraft website to download and found only Rev E. instructions.
Couple of questions:
1) does anyone have the Rev D. version

Hello,
I had a Great short day out on the Appalachian Trail.
Wx was overcast and the temp. was around 77' F.
I was located north of Strausstown, PA about a mile south of rte. 183 at the
pond.
I called CQ on 30 meters from 14:00 UTC until 14:20 UTC, no one came back to
my CQ so I went to 20
Ragchewed with John 5Z4JX (N6JW) who is using a K2/100, on July 20 15m SSB.

I created what I thought was a reliable method of measuring the power out of
my K2 and am puzzled by the results. What I did was:
1. Built the RF probe from the K2 manual onto a 50 ohm dummy load.
2. Attach that to one of the antenna connections on my KAT2.
3. Tune the load on all bands
It means you got to play with the GOOD stuff! 73 de Alex NS6Y.

Hi, guys. I smoked my K1 by plugging in the wrong DC cable. It came from a
35V supply instead of 12V. The radio worked for about 15 seconds, then died
with an odor of burning components; no visible smoke. Realizing what I had
done, I connected it to 12V to troubleshoot. I see only 1Hz pops of (low
Assuming you meant 22 mW, you should indeed use the 251 mW setting of
the jumpers. The 1 mW setting is for 1 mW maximim. You'll be able to
use the input level control to tweak the transverter to full output
for your drive level.

Johnny,
Re-check that output level because it seems quite low. 22mV into a 50 ohm
load is only 9.7 uW power. I would expect something more on the order of 1

Fran,
First, you said 'tune the load' -- there should be no tuner of any kind on
the output of the K2 when measuring power into a 50 ohm dummy load. The
varaition of power within any band can and likely is) a result of an input
impedance varaition in the tuner. If you are using the KAT2, put it

I do not have the Rev D documentation, but the KSB2 has changed very little.
I suggest that you just use the current instructions on the Elecraft website
to build your KSB2 - if you should encounter anything that just does not
seem to fit, then ask your questions here.

Hi Don,
I recheck the manual of my ICOM IC7800. It said a transverter level of
-20dBm or 22mV.
Is -20dBm equivalent to 22mv? Or is there a mis-print in the ICOM Manual?

Good Evening,
That was fun! It appears the bands are getting slightly better.
Either that or the heat has effected my hearing! During the first net I
was going a little dingy from the heat. Good thing they over designed the
heat sink on the K2/100 since mine was getting quite warm. I
The math is already more complex than most folks realize. The output
of the diode detector is not RMS, but rather peak. So, you need to
multiply it by SQRT(2) to get the real voltage to work with. On top
of that, you should add in the diode drop, which is variable based on
the current going
