Uhuh - and how many of you have worked such DX?smile
The signal level seen on earth is 4E-19 or -196 dBw (subtract 30-dB
to yield -166 dBm). The path loss at Pluto (31.9AU) is without
including antenna gain 303.5 dB. Interesting that I read they plan
to run 600bps at 36AU.
Other numbers
This is not the place to post such things.

The dateline is today and the vote happened today, Ken. It might be
boring or inappropriate, but it's hardly old news. The effort to close
field offices has been going on for for a while, and the original plan
included closing 16 of the 24 field offices, but this story is actually
timely.
Hi Alan,
The information is in the manual but you sometimes have to search for these
things.
On page 46, the crystal filter setup page, it states that you should enter a
gain of 1-2 db for the 400 Hz filter. I have a 400 Hz filter and I have
entered 2 db.
I searched the PDF version of the K3
I purchased a 400Hz 8 pole (Inrad) filter and installed it in my K3 yesterday.
There were no markings on the box and some obscure numbers on a small label on
the side of the filter case, but there was no offset figure.
The Cady book mentions that for 8 pole filters an offset is unnecessary, so I
You are correct that the offset is zero for 8-pole filters.
What I do is adjust the filter gains so that there will be no change in
signal strength when switching filters. You can do this by ear if you
turn off the AGC, or you can use the K3's DBV function if you are a
perfectionist.

I have used QSK for thousands of QSOs since I got my K3 4 years ago. I
have seen no changes at all.. but I am not a real QRQ op. I usually run
about 28 wpm... sometimes about 32, and very rarely a bit higher than
that. I did put in the new Synth boards, and have verified that QSK is now
When I first got my K3 in 2009 I thought the QSK was fabulous and used it every
so often. Then for a few years I was working too much and wasa little
inactive. I finally retired and heavy into ham radio once again. I got the
KXV3B for the preamp and had to jump from version 3 somethingmcu to
Hi Bill,
Not really. I have tested full QSK from about 25 wpm up to about 80 wpm and it
certainly seems quick enough to me for those speed ranges.

There were some firmware changes made when the new synthesizers were

that QSK was better.

Are you using the new QSK setting in the menu options? The new QSK setting

The only viable solution for this is to make this a moderated list.
That means that someone (probably Eric) would read and review every
single post before it goes out to the rest of us.
We don't want that, do we?
It's far easier if everyone just follow the rules in the list charter.
I think the Elecraft List Guidelines pretty much covers everything in this
thread.

It would seem that the DX record is held by the Voygers which long ago
left the solar system.
I don't know their power but they still check in from way beyond
Pluto. So NewHorizons is DX but not real DX YET.

Certainly, with a proper transverter (or down converter) and adequate
receive antennas, the K3 could serve as a suitable IF. The decode of
the received data is quite another matter.
Will anyone do that with their K3, I don't know, but the K3 is capable
enough given an adequate down converter.
