Hello,
I'm thinking of selling my K1-4. It has worked wonderfully for me and is in
like new condition. It is loaded with the ATU,* 4 bands - tuned, noise
blanker, backlight installed and I have the K1-2 board built (has not been
installed or aligned).

I have the K1-2 board built (has not been installed or aligned).
I love my K2 and I am thinking of building the KX1 for portable QRP work.
Serial number 2257. This radio is in great shape and working like a charm.
It is for sale for $420 - shipped Firm.

Jeff and gang,
If you're working CW, don't forget about the CW-Reverse feature of the K2.
This feature accomplishes the same thing as IF shift, although the degree of
passband frequency shift isn't adjustable in real time.

In the article from the contester on the Elecraft site, N6 something, he
setup the SSB filters to act a bit like an IF shift. One filter to the
left, one to the right, and one center. Thought that was interesting.

Wyn,
A lot more people than you would expect are not only swayed, but often
convinced about a particular product on the basis of 'a purely personal or
subjective view'.

everything, under microprocessor control). Has anyone done anything to

Tom,
The best that you can do for making specific software (firmware) functions
of your own making is to create the entire K2 control firmware on your own
and burn it into the appropriate chips.
Elecraft keeps the firmware proprietary, and there are a number of valid
reasons behind that - an

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
There are some issues with the ARRL reviews also. They seem to be very
hesitant about saying anything much negative about rigs from the big
boys, but do not hesitate to call a smaller business out on issues.
The way they test is not always indicative of real world usage, as
highlighted in
Bob,
With due respect to Ron, IF Shift is very easy to design into a single
conversion receiver with a selective IF filter *provided* that the IF to

Michel,
That is a great tool, and I am certain many will appreciate it.
There is a technique that avoids the problem - and that is to form the wire
around the OUTSIDE of the core with a finger on each turn. By forming on
the outside, there is not as much need to pull the wire to tighten it. It
