Brendon, I'm trouble-shooting a P3 noise problem (via Elecraft) that
exhibits itself when I key the K3 even when all RF power is set to zero and
the antennas are dummy loads. The circumstances that initiate my fault are
quite different from yours but I report it because the symptoms are similar:

By all means educate me please.
Why would split be used on a narrow bandwidth signal such as PSK31?
Would you not be just consuming twice the amount of bandwidth as needed?
I have casually operated PSK31 and
I have a K2/100 that I would like to occasionally configure as a lighter

If you have one you're interested in selling, please contact me off the

I'd like to not just to thank Don, but to praise him for his help on my KX1
and to both thank and praise him for his helpful comments on the elecraft
reflectors. When I see Don's name as the author of a post, it becomes a
must-read comment. Why? You always learn something when Don speaks.

I have been looking for an opportunity to sing Don's praises, so I can't let
this thread go without saying something. I have never had the benefit of any
service work or personal advice from Don - unfortunately, my K2 kit went
together without any problems and has worked flawlessly ever since
I agree on must read I read very few of the posts - however, I do
read all of his - often making notes for use at a later time.
He is the Professor of K3.

I have, likewise, been looking for the same opportunity. I would venture to
guess that there is no one, maybe not even the K2 designers, who know the K2 as

I bought the KX3-PCKT cable kit along with my KX3 -- my primary interest
is digital modes.
I also see on the list that a lot of you use a sound card interface
instead of cables.
If the KX3 has enough isolation, is more isolation needed?
What am I missing?
Thanks in advance

Hi all,
This release of KX3 firmware has several significant improvements. See release
notes below.
We'd like to release this to beta test on Monday, but we could use some
additional pre-testing. If you're interested, please email me directly and I'll
send you a copy.

Well now is the time for me also add some praise. Without Don a partial

I have been using my TS590 with the serial cable connected to the KPA500

The KX3 has no isolation (the K3 does have isolation).
What you will normally find is that the isolation will lower the base
noise level. How much depends on your computer and soundcard - some are
pretty good already.

My K2 Rev. A worked all the years very well. But as I have the parts for

I have the mini wonder, a KX3 and love this radio. I pride myself on owning a

Gerald,
Did you add the 10k resistors to RP2? If you did, check the value of
RP2. If it is 10k (last digits = 103), then the resistors should not
have been added. OTOH, if RP2 is 100k (marked 104), the 10k resistors
should stay in place and you will have to look elsewhere for the problem.
Wow, that made a big difference in the SSB receive performance. The audio is
no longer choppy on strong signals due to the mute/unmute bug plus the expanded
AF gain envelope makes setting the listening level a real easy task now. The
internal speaker actually sounds very close to natural now,
Paul,
The com port baud rate is a different 'animal' than the soundcard
sampling rate.
The KX3 can operate at a baud rate of 38400 (two zeros), and I would
recommend that the COM port be set to that rate - although that normally
happens automatically.
The com port will provide rig control -

Sorry, just couldn't resist.

Hi Dick
Thank you very much for your detailed explanation.
The methodologies for the auto band switching of the KAT500 are too complex
for me so I will have to stick with the RF sensing, except of course when I
use the K3 !!
Thanks again for your response. It really is appreciated.

Due to the phone contest on this weekend, operating on 20M will be a challenge.
It was today. I considered 17 M, but I spent time on that band with SOTA
today, and it was not good. Enjoy the spring weather (I hope). It reached the
70's here today for the first time this year. See you next
