If the K3 were supplied with a stock microphone, rather than leaving it to

The OP was more about Phase Noise that is emitted by the Radio.
Here is Wayne's response to the OP.
BTW, Jim's call should be K9YC as Wayne corrected later.

No serial connection on the computers

There's one good reason that I know of. The VOX on/off setting is shared by
AFSK, DATA A, and SSB. Having VOX left unintentionally active on SSB is
very bad -- it leads to amp faults and unintended transmissions
I've asked a few times for this to be fixed and swore to myself that I
would never
Indeed it does. I never understand the desire to make things complicated.
Witness the desire to use FSK rather than AFSK with the K3.

On the Sony laptop, you will need to get a USB to serial cord. Be sure to
get an adapter with an FTDI chipset. There always seem to be issues with
drivers, including one that would brick the adapter. I don't know where
that issue got to. The CURRENT model being sold by Elecraft seems to be
working
That sounds like you want to build effectively a VOX circuit (to
recognize the keying tone) and drive the PTT input.
I can think of no good reason to do that because the K3 has a very good
VOX that works well for digital modes.
The only remote reason I can think of would be if you are running
Chris,
I understand your question, I have been wondering the same thing.
And in spite of a couple replies you got, I think it is a good question.
If you find an answer, please let me know, and I will do the same. I have
tried using the K3 VOX for digital modes and I have had problems with it.
Jim, isn't the appropriate PTT hookup covered in your HamInterfacing
document? I remember using it for my TS-830s a few years ago for RTTY.

Something to check, anyway, Chris.

Further the VOX GAIN setting is the same for DATA and SSB. I find I
have to increase the VOX GAIN for digital modes and of course forget to
turn it back down for SSB. Having it per-mode would help. Fortunately I
don't use either mode very much so it's not a big deal.

I asked a long time ago for separating SSB VOX from everything else. I found a
workaround for my needs, but I;d still like it. It's supposedly on the list.

I'm in Carl's situation. I solved my problem with the SignaLink

Thanks for all the replies. I did not wish to explain why I do not want to
use VOX for keying digi from the right channel tone. But as another has

Hi Guys,
I have for sale an Elecraft K1 4 band rig in Excellent condition. This
rig has very low hours on it and a higher SN in the 2700 range. The rig

Bill,
If you are not into 'hot and heavy' contesting or DXing in a pileup
and/or diversity receive, you will find the 5 pole filters quite adequate.
The problem is that the 8 pole filters have a better slope factor and
do not have an offset.
The offset is only important for diversity
I'm a contester, so I have tight 8-pole filters. I've often
advised those who are not contesters to go with no additional
roofing filters and add only on the air experience has taught them that
they need.
Jim, I really hate to burst your bubble, you being a CONTESTER and all.However!

I use the 8 pole Xtal filter, and love it for CW... You are in for such
a treat once you get your K3 going on CW... The rig is a wet dream for
CW ops.

Well let's be clear here...
These are roofing filters, so you will only notice a difference in adjacent

difference between 5 pole and 8

Since you likely have a serial connection for rig control in addition to
the audio lines, you have an alternative to using the Fldigi 'tone keying'.
