Hi Bill, I recently built a KAT100 and 4:1 BL1 also (3 evenings too!). I
have a 160/80/60m trap dipole in ANT1 and a 40m doublet via the balun in ANT
2 for the other bands. This gives me instant QSY on ten bands. Like you,
by coincidence, I find the balun gets very hot on 40m. What I plan
Hi Glenn...
You have done a good job of sleuthing and pondering the various
solutions.
Bottom line is that you may well need to communicate via email with the
boys at Elecraft about this. If they have had other similar reports (or
even if they have not), they will try for a solution. Also, you
Got to see the new amp in action last night at the Crowne Plaza hotel - this
is where the main DX and contest suite is at in downtown Dayton. About 11PM
Eric showed up with the amp, a K2 to drive it and a dummy load. Eric set the
amp up in the hallway for passer-byes to see. I will try to get the
Hi all,
Can someone please explain how Elecraft's revision sheet numbering works?
For example, does a sheet numbered B-3 include all of the changes described
in B-1 and B-2, ie are the sheets accumulative? What causes an
alphabetical level change? Etc etc

I have been hearing stories about this amp since late last year but no one
has shown a picture yet. Maybe the folks belonging to the in group are
told not to disseminate photos or even allowed to take them. As far as I
can tell we will be told the rest of the story late this year.
Kevin.
Hmmm Maybe the same is causing my Hi Curr indication on HF
occasionally.

Hi Jack,
Thanks for this, it makes good sense. I'm trying to work out what's the
best way of tracking the minor improvements/changes that are made along the
way, especially to the optional add-ons, and to catch up with any that are
worthwhile.

Was it a K2?.or a 100 watt K2/100?

It was driven with about 30-40W from a K2.

Recently I saw an exchange about the differences in rx experience of the
Elecraft K2 and the Drake R-4XC.
Is there a Drake list out there I could join which would be a more appropriate
forum to discuss this more in depth so I do not waste bandwidth on the the
Elecraft list?

I believe Eric told me it'll need around 50W drive .. I'm assuming a
K2-100 (I only saw the pics, was busy with the piggy banquet last
night)

At the FDIM hotel, Wayne was driving the new amp with a K2/100, turned down
to about 40W. FCC apparently requires a minimum drive of 50W to create full
output on an amp of this size. It didn't sound like they had made it
through acceptance yet... But the delivery was 3 - 4 months away at minimum

I want to thank all Elecrafters who stopped by the SteppIR booth to see
my prototype E-meter wide dynamic range digital wattmeter kit. Thanks
especially to Eric who offered words of encouragement... a real gentleman.
I was surprised I didn't see more QRPers though, since the E-meter is an
Hi Larry,
I saw your original announcement and checked your web site. At the time, I
thought it was a remarkable piece of equipment and I still do. I'm not
surprised the QRO guys were very interested. But I am surprised that you
don't understand why more QRP ops have not expressed interest.
For
Thanks for the input Eric.
You may be right on a couple of counts. I am only a QRPer in the field,
and tend to be more more a 100-watter at home. Since I had 90dB of
dynamic range to play with, I decided to use it all, thus the 2500W top
end (I also picked 2500W because it represents 2dB of
Yes, it can be controlled by computer and I supply Windows freeware to
do so. The SWR alarm beeps now, and I could add the other features. I
think I like cw better than voice, and I like the idea of a variable
pitch tone for tuning. Variable tone and cw output would be very easy to
add even to
Incredible what a few hours this afternoon tossing the 66 ft wire into the
backyard trees can do. After checking in with Kevin on 20meter ECN with

Here is what I have found: Laptops often have less shielding and produce
more noise, and the switching supplies can be noisy. I have found a
Sony Vaio to be noisy and a Toshiba Libretto and an IBM 500e to be
quieter. The sound cards are often problematic, if you intend to do PSK
or other

Wow, talk about ridden hard and put away wet! The second net took from
0257z until 0317z to dig the last person out. But I am getting ahead of
the story. After that net I had to go outside to discuss the

just break even
