Jim,
If YOU want to use PTT to control your switching please do. But do not
insist that the other 99% of operators who don't use it. For them, VOX
works just fine.
VOX is a PITA in a great many environments - for a variety of reasons.
It just plain won't work in a multi-multi with other
Hi Jim,
First, in my experience 8msec delay is THE ONLY point if we speak about TX
delay. Any setting above 8 msec makes CW choppy. This subject was discussed
here some time ago. It has been checked here on 4 different K3s and they are
all the same.
Second, I do not insist on anything. I have

That is certainly true with QSK and QRO. I like to run QRO as much as
the next guy, BUT many EU contesters work too fast for

Joe,
Please look again at the SUBJECT LINE in this thread. It is about
DIGITAL MODES.
I agree with
Please go back and look at the SUBJECT line in this thread. It is about
DIGITAL MODES. :) We're talking RTTY, PSK, FSK, JT65, Olivia, etc. The
only one of those that is a contesting mode is RTTY. I use VOX for all
of them, with no issues, because I don't have any gear with slow relays.
Jim,
Please look again at the SUBJECT LINE in this thread. It is about
DIGITAL MODES.
Even in DIGITAL MODE I would not trust anything *except* hardware PTT
(e.g. RTS to a transistor/optical isolator switch) preferably with an
external hardware time-out timer - particularly with computer
I use VOX with computer digital modes (primarily PSK). I have
thought of hooking up PTT, but the only problem I have with VOX
is remembering to turn it off when I switch to SSB or FM. With
no serious problems with VOX, implementing PTT barely reaches
the bottom of my long list of projects.

Still interesting what is the percentage of those using VOX instead of
PTT. Just curious.
So far, if we count you, me and Joe the score is 66% in favour of PTT :)
The important thing is that each operator can make his/her own choice

Hi Igor,
First, I suspect we may have a language
What do you mean with Pin 1 problem ? On SUB-D-25 pin 1 is shield,
so I guess you refer to shielding/ground loop problems? The now much
more common SUB-D-9 only has data ground, on pin 5... and pin 1 there
is DCD.

Pin 1 problem refers to an issue originally identified in professional
and broadcast audio equipment where pin 1 of the XLR connector was not
connected directly to the shielded case *at the connector* but instead
connected to the circuit common elsewhere in the device in question.
On SUB-D-25

Although I respect the comments from the experts (and Lance and I worked on
two-meters thirty years ago) I must say that I use a Signallink on HF RTTY
running a K3 and a venerable Drake L-4B without issue.
If I was still on EME then of course I would have the full sequenced keying
hardware.
Knowing that there are a number of KX3 owners who are interested in an computer
interface that does not rely on VOX mode to transmit CW or digital modes from
the
computer, I have outlined the interface that I am using here:

Good luck and happy DXing!

Looks like a great solution, Lance. Just enough, not overkill. Thanks
