K3S + P3 + SPE Amp

Gentlemen,

My first post to the list , although an avid reader.

Has anyone here done the connection of a K3S plus a P3 Panadaptor with the
P3SVGA and Monitor functions , to a SPE 2K Amp?

Is there special cabling?

What Config Menu settings are used?

The cable supplied with the Amp is a DB15M (amp end) to a DE9M (K3S end). I
am using this in conjunction with the Elecraft Cable E980297 which is an
RJ45 to DE9 Female. Config menu is set to RS232 at 9600 Baud , this works
fine and the amp follows the K3S. However I lose the Frequency readout on
the P3 by having to disconnect the CBLY3Y Y cable at the RJ45 connector on
the back of the K3S. If I connect the DE9m of the supplied Amp cable to the
DE9 of the "Y" cable , when plugged into the K3S , amp will not Band change
from K3S.

Is there another method of cabling so as One does not lose control of the
P3?

Thanks & Regards

David

Re: K3S + P3 + SPE Amp

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

Re: K3S + P3 + SPE Amp

In reply to this post by David Holton

David,

If you are using the E980297 RJ-45 to DB9M cable, you would connect that
cable to the XCVR port on the P3. Then plug the "Y" cable (not the
Elecraft CBLP3Y) into the PC connector on the P3. One end of the "Y"
cable goes to the PC and the other end goes to your Amp cable. See the
figure on page 5 of the P3 manual.

OTOH, if you are connecting the PC to the K3S through the USB port,
refer to the figure on page 6 of the P3 manual. In this case, you would
use the CBLP3Y cable instead of E980297. Your "Y" cable connects on the
PC connector of the P3 - one end of the "Y" connects to the end of the
CBLP3Y that would normally go to the PC connector and the other leg of
the "Y" connects to your amp cable. If you are using this
configuration, set the RS-232 menu to USB.

73,
Don W3FPR
