Hi Fred
Any antenna heavily loaded with coils will show a narrow bandwidth.
In effect, the coils and the capacitance of the antenna elements
across them form a tuned circuit. The higher the Q of the tuned
circuit (meaning the lower the coil losses) the narrower the
bandwidth, but the higher the ef

Try pushing with the eraser of a wooden pencil.
This gives you a non-skid pusher with a wood handle.
Also keeps finger tips from getting burned while
melting the solder to allow the part to move.

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 ,standin
One additional thought.
It is not unusual to use an external AF filter with
headphones. I have a homebrew passive filter
that I put in line occasionally. It is not needed
so much for additional selectivity as to reduce
higher pitched white noise that comes through
along with signal.
You can buy t

There are two actions I would recommend.
First is a rotatable receiving loop to help reduce
local noise. The best way to reduce noise is to
prevent it from entering the receiver. It can be
tuned or untuned. If tuned, it will be more
sensitive, but limited to one band. If untuned,
it will

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.
Good luck and 73

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 t

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 times

Except when I forgot to tap :-)

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 opening
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

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

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.
Good luck and 73

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.

Yes, I use a keyboard during contests, but not for sending

In a contest, the exchange is pretty cut and dried, and lends
itself to computer use. I have all my exchange info stored
