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
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
Layout like Yaesu FT950
VFD display - blue

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

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

Hi Tony,
You'll get somewhat better isolation using the BNC jack for the sub

Either way, the trip point of the KRX3's carrier-operated relay is

Charging Li-Po cells is a little bit different but not difficult. I use a

the point I just stopped using the K3 for CW. I know Paul says the audio is
one of the best designed audio circuits for a communications receiver.
Hi Fred. The answers to your questions are mostly yes. Read the following

answer more specifics if you need them.

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
For contesting, it is WAY more effective to be able to control the DVR

on hitting Esc[ape] iff the COM port configuration has Radio PTT

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

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),
Tom,
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,
