Hi Wayne,
Assuming that you had nothing else to do (!!), a Mk II version of the K2
using a different and higher IF than the presently used 4.914 MHz IF might
be worth conside
Hi Geoff
I would think that the phase noise limitations of the K2's design would limit
its appeal.
I would be more interested in a K3-Junior
Maybe this K3 junior would have a single receiver
Inbuilt power supply
200 watts 50 volt or higher fets

The K2 is a very mature product, and I don't anticipate adding further
internal modules to it. I've thought about a Li-Ion battery as a
replacement for the present gel-cell, but it's still too expensive and
is thus left as an exercise for the reader.
The P3 should work with the K2, though
Any transceiver can be improved. But working on the K2 again...
Elecraft would have to make a business case first and then decide.
Anyway, my K2 is just fine as it is, and it's on duty for the next few weeks
as one of the transceivers in the TY1MS dx-pedition.
I already worked them with my K3 :

I don't think most people looking at the K2 are that concerned about state
of the art performance. The K2's main qualities are small size, low weight
and low power consumption
Hello Julian,
Yes, I agree with you. Elecraft is very clever in segment the market to suit
different market demand.
Although I do not always clap my hands for K3, K2 is definitely the best choice
for portable use. Upon replacing the Lead acid battery in the KBT2 with Li-Po
cells, the K2 is n

I am not certain where that statement about phase noise comes from, nor
if it is valid. The K2 comes in at -123 dBc (or -124 dBc) in the phase
noise category.
The transceiver comparison list at the Elecraft website does list phase
noise as measured by ARRL and by Sherwood.
I did a quick count -
Before the recent change in the IF sample circuit, the transfer gain was
around -15 to -17 dB. In other words, a signal input to the antenna will
appear at the IF sample port about 15 dB below the input level. This
assumes the K3's preamplifier is off and, of course, that the K3 is
tuned to wi

Hello Julian,
Charging Li-Po cells is a little bit different but not difficult. I use a
multifunction intelligent charger bought from Radio Control players (only US$50
locally). I need to modify a bit on the charging circuity. Don's webpage

Hi Fred. The answers to your questions are mostly "yes". Read the following

My vote would be to bring some of the K3's DSP algorithms - especially the
noise reduction - to the
K2's DSP board!

As I see it the advantage is that you can send messages from the keyboard
(particularly useful if you have an SO2R setup with the radios spread
apart). Furthermore, you can integrate the message sending into the normal
message sending functionality, like message repeating and hitting E
For contesting, it is WAY more effective to be able to control the DVR
from N1MM than from the front panel of the K3. It's tiring and wastes a
lot of time to move your hand back and forth between the keyboard and

By the way, I since found out that the "RX;" command is sent to the K3
on hitting "Esc[ape]" iff the COM port configuration has "Radio PTT
via command" checked. This has the nice effect of canceling DVR
playback on hitting Escape.

Hi y'all!
I have noted that most of the posts in the elecraft reflector are about the
K3. I hope this isn't out of line.
I bought a K1 awhile back because it was billed as a great first-time
builder's kit. As one of those first-time builders, I suppose I'd agree,
but I've run into a few rather b
It's just a matter of what you are used to, Brett. Most contesters I know like

Hi Tom,
Both varieties will produce the DC voltages you need (as would a few
batteries). For your purposes, the differences between the two types may
not matter.
Linear power supplies use a conventional transformer to convert line
voltage (117vac) to a lower voltage (typically 15-18vac), which

Yes, K1 questions are welcome here - after all, it is an "Elecraft"
reflector, not a "K3" reflector. The relative newness and the
popularity of the K3 does make the bulk of the traffic K3 related. For
that reason, many on the reflector want us to remember to put K1, K2,
K3, etc. in the

I use Logic 8 as a logging program, and it has communicated fine over a

It's official: we're running out of DSP cycles not just during NR on/

I get a continuous DSP red LED and distorted audio (with a buzz) under
the following conditions:

CWT on
NR on, set to F1-x
DSP NB on, any setting

While admittedly draconian, my solution to this problem was to dump
Logic 8 and its PC platform and use MacLoggerDX on a Mac. No further
problems.
