Remoterig does not support the P3/SVGA nor does Elecraft offer a remote option 
for the P3.    I have the K3/0-Mini along with the K3-KPA-500-KAT500-P3 at my 
ham shack in southeast Georgia.  

I’m aware of two options for ’seeing’ the P3 remotely:

1. Install a video capture board in the ham shack computer and camera aimed at 
the P3 and then view the P3 by accessing the ham shack computer to see the 
video.  However, I’m not aware of any currently available video capture boards 
per se.  You’d have to search to see if these are still available.  This 
approach has been discussed in the past on this reflector, but it has been 
awhile since anyone has posted anything about it.

2. Use the IF output from the back of the P3 and connect a SDR receiver (such 
as SDRPlay devices), install the appropriate SDR software on the ham shack 
computer, and install OmniRig to have the software track the frequency of the 
K3/100. I have done this with SDRPlay's SDRduo running their SDRuno software 
that has the ‘hooks’ for OmniRig.  It is then possible to view a spectrum 
display running available through the SDRuno  that will replicate what the P3 
can show directly.   When I turn on the RX ANT on the K3/0-Mini, it allows 
OmniRig to interface between the K3 and the SDRuno software and subsequently as 
I change frequencies/bands on the K3, the SDRuno software follows along.  I can 
also set the frequency of the K3 by specifying the frequency within SDRuno 
software.

While I’ve done this with SDRPlay hardware and software (I already had the 
SDRduo in my shack before trying this), presumably the same thing can be done 
with “SDR dongles” such as NooElec using other SDR programs such as SDR Sharp, 
SDR Console, etc.  However, I don’t know if these packages provide the OmniRig 
interface to ensure that the spectrum display is controlled by the K3.  SDRPlay 
also offers single tuner SDR devices (SDRduo is a dual-tuner) such as the RSP1A 
and RSPdx. See: www.sdrplay.com <http://www.sdrplay.com/>.

Bottom line is that the “work around” is to have a PC in the shack that can 
utilize a SDR device (connected via USB) with an IF input coming from the P3 
that can subsequently be controlled by the K3 to show a spectrum display.  This 
means you’ll also have to connect to the PC in the shack through remote 
software such as VNC Viewer (from RealVNC.com <http://realvnc.com/>) or another 
package such as TeamViewer.  The SDRplay website does have generic 
documentation and videos on how to connect HF transceivers to their SDRs and 
how to configure SDRuno so that the SDR can provide a spectrum display (As I 
recall, they use the Kenwood 570G as their example).  See:
