Vernon,
If your K3 is receiving static, I would tend to blame your problem on
the antenna rather than the K3.
However, there is a way to check the K3. Beg, borrow or purchase an
Elecraft XG2 signal generator. That will give you a tool to produce a
50 uV signal (S-9) and also a tool to do
I just tried FLDIGI recently and liked it very much. I like that it is a
truly cross-platform program so that no matter what type of computer I am
using - Linux, Windows, etc.- I have a program with the same interface to
use.
I recommend the Belkin F5U409 USB to Serial adapter. I have used
You don't need a fancy antenna to receive lots of signals on HF. A
random length of wire should yield plenty that are above S3. My main
antenna is a simple 100 ft length of wire 30' high which can often
work DX stations in a pileup, let alone receive them well; and this
with only 10 watts output.
Johnny,
Because you like to build, please do not think that SMDs would be too
difficult for you to handle. I, and no doubt other people, felt the same
concern before starting to use SMDs in homebrew projects. Mounting multipin
SMD ICs is not difficult after some practice.
Tweezers of the
Vernon. Try the recommended dipole to test your rig. A dipole for 20 M band
is short (about 36 ft long) and easy to make, you will quickly hear whether
there is an issue with your K3 hardware or setup. The 20 M band is reliable
most daylight hours and shortly after sunset.

This is getting out of hand. Vernon can't receive anything and someone

hundred might make a few DB difference but certainly not enough to overcome
a dead receiver.

Steve is right. It ain't the antenna. I can hear plenty of signals with the
previously suggested screwdriver in the antenna jack.
Vernon, turn up RF gain all the way, put the mode on USB, and tune in WWV at
10 mhz, and tune down from there through the loud broadcast stations Or tune
20M phone
Personally, I doubt that adding radials will make any noticeable
change in the number or strength of received signals.

Have you checked your coax , maybe open.
Try hooking up just the center conductor of the

The K3 connects to a computer thru a DB9 connector for RS-232 communication.

I have a different opinion.
I like kits. The stereo I used in college was a Heathkit I built

I built the K2 and learned a great deal from the experience. I had at
least as much fun building the radio as using it.
Building the K3 is indeed much less of a kit experience. This is
Here's a follow-on question to the reflector...
Vernon's set-up brings a question to mind. He says he's using a 4:1 balun on
his vertical. At first brush that seems counterintuitive, doesn't it? Isn't a
vertical unbalanced? Certainly the coax is unbalanced. When you're mating an
The only possible reason I can think of for using a Unun or Balun with any
end-fed (Marconi) antenna is to minimize RF on the outside of the coaxial
cable shield. But that seldom works because much of that RF is induced by
the field around the radiator itself, not caused by RF flowing around the
I've heard quite a few people use balun, when they meant impedence transformer
or unun.
I heard somewhere (and the tapes have been erased) that the 43' length came
about
because it was the most economical length for a manufacturer to cut stock with
the
least waste to meet shipping
The 43 foot length is the optimum length for low angle radiation on 20 meters
(5/8 wavelength). It is also not an even half wave on the other bands so will
match reasonably well with a proper coupler and a 4:1 unun. It is a vertical
equivalent of a G5RV.
Willis 'Cookie' Cooke

That's quite possible Mike, but there's an electrical reason for the 42'
10-80 meter vertical height.
42 feet is 5/8 wavelength on 10 meters. Above that length, the pattern
shifts skyward quickly which greatly reduces DX performance on 10.
It's still long enough to be very efficient on either
Good point Cookie. I was not considering a Unun that is also an impedance
transformer. They really are two different things, although in some special
cases such as you describe they can be combined. Another very common one is
the 4:1 Balun used to feed a folded 1/2 wave radiator.
Ron AC7AC
None of these old wive's tales are true.
The 43' length is a convenient non-resonant length - nothing else.
The balun was chosen originally because the 43' vertical was originally
planned to have one or two elevated radials only (making it balanced), and
it would load fine with a balun.
The
All this has nothing to do with his K3 but what about a Choke Balun? Is it
really a balun or is it a unun? We use the same device to feed a ground
mounted vertical to reduce RF on the coax and to feed a balanced dipole
with coax. It's both a balun and unun depending on how it's used.
Quite right, Dave! I see Cookie has the right number.
I'll cc the elecraft list to prevent any confusion, Hi!

Ron,
43' is actually 5/8 on 20 meters, so the vertical is not so hot
