Just a quick note to let you know that my KX1 is singing (and listening)
nicely. The receiver nearly deaf problem was discovered to be an open L5
which is part of the 14 MHz LPF. The short story is that without the 5.6 uH
inductor, the filter was essentially sending most of the signal from
Hi John,
The only advice I can offer is from experience. Unless you string it up on
a very cold day, be sure to leave a good catenary for contraction later on.

I missed the earlier question. Count me as another leftie (write
left-handed, bat right-handed, use paddle right-handed). I had no real
problems winding the toroids. One toroid in the middle of the set was
wound backward, discovered on inspection after winding but before
installation, and

sure this depends on the person, but the K2 ProSet hurts my ears

I am going to go in another direction on wire size for long spans.
I have been using the silky #18 and #26 from the wireman for all my
antennas. The trick for keeping them
up is to use a Dacron rope for a messenger line that supports the very
light wire. With the rope strung

How about this: Copper-coated steel wire. In the USA this wire goes by the
name of copperweld or copperclad steel.
Diameter is 1 mm and black coating is UV-resistant. Takes loads up to 40kg.
Most important of all it's almost stealth and Your neighbours will love it.

I like the way you think, John. THAT is engineering.

If one is building an antenna for an EOC you do NOT want to use too small a
wire, and its attendant weak breaking strength.
Use no. 14 or larger wire, stranded. Use heavier duty insulators, good
ceramics or glass if you can get them in place of plastics which deteriorate
in the sun in a short
For an EOC operation, you want an omni direction of coverage. Put a usual
antenna height, and end fed 270 foot wire on 40 m or even 80, is going to be
getting to be directional toward the far end of the wire.
MUCH better for EOC use is to put up such a wire as a center fed doublet.
Then it
If you choose to use Copperweld, be very careful to not
nick the copper cladding, or the steel will eventually rust
and the thing will come crashing down. Copperweld wire
also needs gentle bends and hopefully lead-lined holes
in any insulators.
I would suggest you contact your power company,
I'll bet it wouldn't take much arm-bending to get the
power company to use a bucket truck to put the thing
up ... especially if a reporter was alerted of a local
interest story.

After some experimentation - I decided to bite the
bullet and BUY a K2 toroid-set from TOROID GUY. I
felt it was the best decision I made in my K2 # 5422
build.
I could never convince myself I ever got the tinning
operation done well enough, and was also worried about
nicking the fine toroid
I cannot speak about the Toroid Guy...he has always had a good reputation, but
I also dreaded the thought of winding toriods. Well, I tried a couple and soon
found that I loved to do the work. In fact, I have had a case of toroid
winding depression, but I got treated and am now better.
Over the past year of lurking and taking in all the info I could from
this newsgroup, one person has continued to stand out when it comes to
helpful advice and troubleshooting skills.
After the first sign of problems with my K2 this evening accompanied by
the panic and fear of never stroking the
After some pushing the LPF turns back and forth I was able to get all bands
between 3 and 4W with a gel cell supply. Which I guess means it's time to get
out and throw some wire in a tree. Thanks for all the help.

I'll second that. Don has certainly helped me with my building problems and
with understanding how to alignment my K2. His help was greatly appreciated.

Well said Jim. We are very lucky to have his expertise available to the
Elecrafter community. He graciously provides his time and knowledge to all
who ask. We owe him a great deal, and I'm glad you brought it up.

My K2 S/N 3202 exhibits what seems to be undue loss of sensitivity as the CW

Spectrogram, and signal tracing through the receiver IF section, I purchased

Hi gang,
I think my K2's crystal filter/BFO alignment (CAL FIL) is messed up, and I
need a bit of guidance...
Should the pitch of the background atmospheric noise change when CW RV is
toggled on and off? Mine changes greatly, but it seems that it shouldn't,
if all CW RV does is switch
