For 40m, a rotatable loop could be as simple as a diamond shape
with maybe 3 ft sides. All loops are not made out of rigid coax
in a 10 ft diameter circle. Also, multi-turn looops allow for a smaller
size while still giving good performance. A 3 ft loop wouldn't be very
large, and

I remember reading somewhere that switching supplies
require some minimum load to be stable. You could
try putting a small resistive load, maybe 50 mA, on the
P/S and see if it calms down.

Hi Fred
I run my K2 at 5w all the time as a QRP station.
I enter many of the major contests and have a
great time.
You do need to be a bit thick-skinned, though, as
you will often be walked on by higher power stations
that just don't hear you. Or they call the station you
are calling at the same

It all depends on the type of noise you experience.
For some kinds of noise, the KNB2 works like magic.
For other kinds, it has no effect at all. For some odd
noises, it sort of works.
Ultimately, it's a crap shoot. It is an inexpensive option,
and I would add it as insurance for those

You didn't mention what kind of openings, if any, already exist in
the shed walls.
Two things you can do.
1. Put a gradual twist in the feedline, say one revolution every
six feet or so. This evens out the unbalancing due to the nearness
of the metal shed.
2. Where you do find an
Obviously, tapping A=B is faster, easier and probably more accurate in the
rush of a contest situation.
Except when I forgot to tap :-)

Hi Kevin
The N7WG Bill? you show is actually me.
N0SS miscopied my call when I checked in.
I was working on my antennas and tuning
across the band when I heard the net, so
decided to check in, just for the heck of it :-)
Was QRU, so just went on with my antenna work.

Hi Ron
One of the strengths of the K2 is its single-conversion design. That is, in
part, responsible for the extremely good specifications the receiver enjoys.
However, i.f. shift such as other rigs often feature require a
multiple-conversion design with all the issues that come with additional
Hi Sverre
The problem with the in-line volume control is that it will reduce the
desired signal
also. What is really requested here is a way to reduce the sidetone level
when using
headphones, but leaving it relatively loud when on speaker. That would be a
neat
programming feat for Wayne, but I
Hello Elliott
The KDSP2 and the KNB2 work together. The KNB2 blanker handles
pulse noises, while the KDSP2 works more on the white noises you
hear. Neither by itself can do the whole job, but together they work
just fine. Sometimes one kind of noise will predominate, and some-
times the other.

Some years ago the xyl and I took that cruise and had a fine time.
I took my HT along and was able to talk on a variety of repeaters from
W7s in the Puget Sound area to VE7s along the passage to KL7s
up in the Alaska panhandle.
Hope you have a nice trip.

Hi Kent
I went through this a while back.
QRP for every contest I could find is spec'd at 5w out,
cw or ssb.

You should request 5w, as the rules call for 5w from the transmitter, not
the antenna.
Good luck. Hope to hear you and work you.

Hi Alan
Yes, I use a keyboard during contests, but not for sending
conversational sentences.
In a contest, the exchange is pretty cut and dried, and lends
itself to computer use. I have all my exchange info stored
under various F-keys within my TR-LOG contest logging
program.

Hi JT
You mentioned the tree with a 50 ft support point.
What do you have to support the ends of your wires?
Also, what kind of real estate do you have to spread out
over? That would help us a lot in suggesting something.

You won't regret buying the LC IIB meter when you can.
It is pretty much the defacto standard among QRP builders.
