I mistakenly gave the wrong christian name for G5RV in reply. Was pointed
out correctly by Peter, G3PDL that it was Louis Varney. Reg Varney was a more
infamous UK TV personality of the past.

I don't think you want to take the speed below 10 wpm. If you can't
copy at that speed, increase the space between the letters. If the
letters themselves are too slow, they can be hard for others to copy.
Increasing the spacing between letters will give you time to compose
the next letter and

Hi
I have been getting a lot of questions about my Solar Controller Kit. This
should answer most of them.
What is it and what does it do?
This is a small 2x3 circuit board that allows you to connect a solar panel
to a 12 volt sealed lead acid or lead acid battery to keep it charged. The

I have never understood “the thinking” with many Ham’s when the discussion

The KRC2 Version 1.3 updaters have now been posted to the Elecraft
Manuals and Downloads web site. This is a bug fix update. It corrects
a rather nasty problem with BCD band output that shows up on the

Hi,
I'm a bit of a newbie when it comes to HAM radio, and the K2 is the
first serious electronic project that I've undertaken. I have now
come to a point where I need to seek some advice from people who are
more experienced than I.
I'm currently measuring the range between the high and low

Wow, thank you very much for such a quick response!
As it happens, I already have a 10uH choke installed, so I guess my
next step will be to contact electraft's parts department and ask if
they'll send me a 12uH choke to try. Hopefully this will resolve the
problem.
Thanks again for your help!
After my post yesterday about the accuracy of the Heath Cantenna dummy
load being found to be off value, I started wondering about the original
specifications and did a little search.
Heath spec'd the Cantenna as having a VSWR of 1.5:1 across the HF range.
Now, if the reactance is negligible

Hi All,
I (a Ham to be) am planning to buy a K2 in the future. I am
planning my antenna now and am going to borrow a radio in the mean time. I
am planning on building a simple dipole that will stretch from my rooftop to
a neighbor's tree. I would like it to be a total of 131' long
Rich,
You will need the Elecraft balun kit for the feeder at the rig before it
connects to K2 by a short coax jumper.
You can use any plastic that has no conductive material in it as insulators.
The one you mention is fine, (plexiglas). You can also use PVC plumbing
fittings from Home Depot, or

Does the ladder line connect directly to the K2?
No, the K2 has unbalanced output. But see below.
Do I need a balun with this setup?
You need some means of connecting the ladder line to the K2 without
unbalancing the feedline. The best way to do this is with
I guess one of the issues, are you ordering a K2 with its auto tuner?
In that case, my suggestions apply, to adding the Elecraft balun, and using
the internal K2 tuner for your antenna. It is also true that a balanced
line tuner will work after the K2, and before your ladder line.

Hi
I had several more questions on the solar controller
Will the controller work with Volkswagen panels?
Yes these panels work very well with a small battery and the controller.
This is a good match for a K1. A K2 really needs a little more power so two
or three VW panels can be paralleled.
Hi all,
OK, I think I have all the upgrade modes working on my K2 #402. It was
a lot more work than I thought it would be; lots of changes. The CW
filters seem significantly better than before. And the SSB filter looks
quite flat.
However, I just installed the KDSP2, and based on the

The DSP is incredible. Especially after I studied the manual and
fiqured out some of the basic procedures, like knocking the noise
reduction in and out quickly on CW, changing the center frequency, etc.
Keep in mind the front panel shortcut with the latest K2 firmware.

Hi all,
I ordered 2 shoulder washers, 2 spacer washers, and a bunch of the soft
plastic thermal insulators from Elecraft so I can finalize the job of
doing the upgrade mods on K2 #402.
I was just wondering about the theory of this layout. The tab of the
transistor is pressed against the
Since you aren't trying to make the antenna self-resonant, you will need to
have an antenna tuner, as others observed. The tuner will convert whatever
impedance the antenna presents at the end of the feedline to 50 ohms as
required by the K2. That impedance will vary depending upon the band, and a

Steve,
If the proper materials are used, the height of the transistor tabs (with
thermal pads attached) will be only slightly higher than the 2-D fastener
(by about the thickness of the thermal pad). So when the heat sink (rear
panel) is attached, the transistor tabs will be in full contact with
28 matches
