[Elecraft] P3 / K3 / SteppIR / DXLabs

[Jack Berry]

I have just added a P3 panadapter to my station and need to work out the 
communication with this new device and the existing ones.
My setup currently works fine with the SteppIR controller tagged into a Y-cable 
from SteppIR (RS232/DE-9). The anchor back to the USB hub is the ElecraftUSB 
cable (FTDI chipset).

When I add the P3 panadapter it works fine in all respects expect tracking the 
K3's frequency. If I then launch Commander the P3 displays the current frequency 
but doe not see any changes in frequency. The K3 and Commander continue to 
communicate in both directions relative to frequency changes but the P3 is blind 
to changing frequency, but the P3 does continue to work fine in all other 
respects.

At this time I am not attempting SteppIR control with logging software. If 
simply adding another Y-cable will do the job then the SDA-100 controller for 
the SteppIR might add on without a problem.

I'm in over my head in trying to understand which way and in what order is 
flowing and also how it needs to flow. Any advice is appreciated.

Thanks,
