Subj: Update and further Elecraft K2 Discussions

Hi Joe,
Just a short note as I cannot be on the net today.
Worked OX2K on CW 559/569 and SSB 55/55! Also worked G4CCH on Saturday.
Heard many of the regulars working OX2K as well. Along with the regulars,
heard many stations not heard before on 23CM: HB9Q, K0YW/5, W5ORH, etc.
Further the discussion on the net about the Elecraft K2 and its excellent
receive performance, but lack of sufficient RIT for 23CM EME work. Roger,
W3SZ, not to be confused with Roger, W7SZ, who is also been a player,
posted a message on Moon-Net that might be interesting to the net relative
to the Elecraft K2.
As you remember Larry and I mentioned this equipment at separate times on
the net during the last few weeks. As a result of these discussions, Emails
to Elecraft, etc. Elecraft is making available an option which will provide
sufficient RIT range for 23CM EME use. It is known as the K2XRIT and costs
$29.95 extra when a K2 is ordered.
Thought you might like to post in the Net-Notes the availability of this
option. W7SZ, W3SZ, and K3AX are not employed by Elecraft, hi hi.

Subj: Elecraft K2 for 1296 EME

Hello, all!
Harry Price, K3AX (formerly K3HZO) has asked me to make all of you aware of
an option for the Elecraft K2 which he arranged for Elecraft to make
available. Several of us have been very happily using the K2 as IF for EME
for nearly a year now.
I have been using the K2 with my SSB Electronics LT2S Mk II Transverter on
144 MHz EME and have been very happy with it. Harry and Larry, W7SZ are
interested in using the K2 as IF for 1296 EME, but were put off by the
maximal RIT of +/- 1.2 kHz given the potential doppler shift on 1296.
Here is what Wayne Burdick, of Elecraft has offered:
I took a look at the firmware, and what is doable is to make the low-range
RIT +/- 1.2 kHz at 10 Hz resolution, and high-range +/- 3.6 kHz at 30 Hz
resolution. You can assign the RIT range switch to one of the programmable
function buttons as usual. (This may or may not be useful: the offset is a
function of the pot position, so switching ranges will also induce a
frequency shift unless the pot is at dead center.) For what it's worth, the
K2 also has XIT, with ranges identical to RIT. You can turn both RIT and
XIT on at the same time, too, which is useful in some circumstances.
I wish we could give you 10 Hz resolution at the high range, but that would
require a hardware change, i.e. swapping the pot for a small shaft encoder.
Anyway, if the above scheme seems satisfactory, we'll go ahead with a
special version of the ROM, which will set you back an extra $29. Let's
call it the "K2 Extended RIT/XIT Range Option," order number K2XRIT.
---end of Wayne's post.
The Elecraft site is http://www.elecraft.com for those who are interested.
This option is hot off of the press
and is available now.
I understand that there was an interesting discussion on the 432/up net
regarding the K2, but I don't have the summary of that to post.
My K2 tested out as follows last August (tests by K3BFA):
---start K3BFA data:
FREQ PRE-AMP ON PRE-AMP OFF
28.2 -147dBm -144dBm
24.1 -141 -137
21.1 -147 -141
18.1 -147 -144
14.1 -148 -143
10.1 -147 -144
7.1 -148 -144
3.5 -149 -144
All tests performed with HP-8656B signal gen, confirmed with an
HP-8662A signal gen because the numbers were so good I began
to suspect the accuracy of the 8656B. I also had a witness in Ed,
WA3WSJ (who I noticed had his fingers crossed behind his back
in the hope his was better).
We also looked at the output on all the bands at the 1/2 watt level
and found no spurs whatever. That 23 mHz osc is about 55dB
down in the receive mode on 28 mHz, but goes away when on
transmit.
Interesting to note the poor(?) performance at 24.1 mHz. Do you
remember perhaps rushing the alignment on that band?
Results shown were the same regardless if the AGC was off, fast,
or slow, and all measurements were made in USB mode, with
headphones.
Guess I'm just going to have to order one!
---end K3BFA data.
Questions/comments welcome.

Hi Joe & Gang;
I am not trying to avoid the Net believe me...have been very busy and in
Nova Scotia a couple of time over the past week or two.
Just a quick note to tell you we have been doing some work on my dish
feeds....getting the winter salt air out of them, hi.
We were able to work the OX2K Expedition in Greenland on 23 & 70 cm this
past week... both bands with very good signals.
If I am around I will check into the Net perhaps tomorrow...busy moving our
Daughter.
Thanks & Best 73, Darrell
