[Elecraft] WSJT-X Problem with K3S

[Guy Olinger K2AV]

Can't argue entirely with success, but often folks just want to put the
trouble In a cage so they can get on with having fun. I get that, it's a
hobby. For sure, been there done that.

But all you have done for the moment is put the snarling dog in a cage
where it can't bite. If you ever run an amp the trouble is likely to return
in some form. You still have the snarling dog.

And there are unanswered oddities like why the RFI only affected the one
sequence of commands.

For others reading this thread, the exhortations for VOX or PTT are
very well taken, particularly where deciding on methodology is part of
planning.

Having a PTT and not-PTT signal available to the station *system* can be
very useful for such things as shutting off remote RX amps during transmit.
Many PC station programs like N1MM+ can add transfer delays only where they
apply, as do WinKey equipped devices which can apply CW key speed related
"word space" intervals.

Not-PTT drives a simple circuit to supply a keyed 12 VDC supply that is
only on when it's safe from TX induced voltages, and can drive relays
to detune towers and de-resonate wires when RX.

Given that the K3S board has both a USB/serial chip and a sound card on it,
no workable scheme proven robust for the K3 has to be discarded for the
K3S.

All that aside, glad you you managed to cage the snarling dog, by whatever
means.  :>)
