[Elecraft] K3S + P3 + SPE Amp

[M. George]

Hi David, I have a 2K-FA interfaced with a K3s.  I don't have a P3 in the
mix, but I made a YouTube video back in March that describes in detail
(maybe too much detail!) how I use Win4K3Suite and com0com to share the CAT
interface on the K3s.  My solution leaves the RJ45/RS232 out of the mix
with the 2K-FA integration so that I believe you could still use the
special P3 cable along with the output of the RJ45/RS232 to allow your P3
to follow your K3s.

You could also accomplish what I'm doing in the video with LP-Bridge to
share the CAT IO on the K3s, however I prefer Win4K3Suite with the com0com
virtual serial port pairs.  I get into the details in the video.

Anyway, here is a link to the video
<https://www.youtube.com/watch?v=Ku8Gyl0amRY&t=485s>: (
https://www.youtube.com/watch?v=Ku8Gyl0amRY&t=485s)  In general this video
will give you some ideas on sharing the CAT interface with several software
applications and hardware (the 2K-FA in this case).  Plus I go into detail
on the interface cable and wire up the 2K-FA to use transmit inhibit and
external ALC with the amp. (both easily turned off in the K3/S if you so
desire on the fly).  You won't use the external ALC in this case to control
the output level on the 2K-FA... again, I discuss this in the video.
EXTALC in this case is only a safety measure to let the amp back off the
drive of the K3s.

I hope you find the video helpful... Max NG7M
