The important thing is that each operator can make his/her own choice

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.

Even in DIGITAL MODE I would not trust anything *except* hardware PTT

That is certainly true with QSK and QRO. I like to run QRO as much as

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

Hi Igor,

Although I respect the comments from the experts (and Lance and I worked on

"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-
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.

In addition to the deficiencies Joe and Lance have noted, the Signalink
also has Pin One problems, which are a well known cause of RFI, hum, and

With the "rush" by hams to using laptops for their ham station (lack of
