The major issue I've found in using VOX for data modes lies in the fact
that any noise {hum, buzz, clicks, broadband noise, Windows sounds,
RFI, etc.} coming out of the computer can and will trigger the VOX.
This is specially true if the VOX gain is too high. Also, the VOX delay
does affect turn-a-round time and must be set to minimum. That in
itself then requires the operator to change VOX gain and Delay when
reverting to SSB. Of course if one doesn't use VOX for SSB it is a non
issue. And if in digital modes the VOX Gain is high and such that the
system is driven into distortion, VOX audio chain, that will affect the
delay time.
I agree with Don in that I find CAT is the better and most assured mode
for transitioning between RX and TX. As to CW using VOX with the K3S,
that is totally internal to the radio. A very different condition than
one running an external application.
At the same time, I am not exactly clear on using multiple decoders. I
presume from what I've read, then each decoder has the option to
transmit. Thus the issue of conflicts with port assignments will likely
arise. Me, I prefer to keep life simple and use one mode at at time,
running the application from the base application and not from within
other applications. I find life to be simpler and much less stressful
but more reliable, thus not having to frequently determining what
changed and why it doesn't work today.
This is totally independent on running one application and one decoder
or multiple applications and decoders. It is not a race, it is a
hobby. Thus coming in first has little merit.
Just remember, we are all going to get to the same place at sometime in
the future. The mortuary cooling slab could likely be one place.

VOX is a lot easier to configure for digital modes than is is for
voice because, all the digital modes -- at least that I know about --
are either on or off. None of them use different volume levels to
encode data. This means that you just have to find a setting between
zero volume and full volume, and it will work well for keying the
radio. If use VOX for voice, the same setting should work for digital.

Although several others have had success with VOX, I find the most
reliable is to use PTT via CAT command. Set it in the application
and you will have no problem.
