[Elecraft] P3 Panadapter Cable Connections

[Ken K6MR]

Do not use a Y cable.  I could go into the whole technical description, but don’t.

I’m assuming here a normal non-USB K3.  What you should do is connect the P3 normally to the K3 through the XCVR port on the P3, and then connect the Microham device to the PC port on the P3.

Subject: [Elecraft] P3 Panadapter Cable Connections

Gentlemen:

I recently purchased a P3 and connected it to my K3.  The installation shares the RS232 connection with a Microham USB interface III for digital operation.  I used a Y cable to connect both of these units simultaneously.

I find I cannot run both at the same time.  If I do, the P3 does not display the frequency at the top of the screen, and does not display the band-pass of the VFO A.  Each unit will run separately with full function.

Has anyone else experienced this interaction?  Were you able to adjust the connection to allow full function of both units?  How did you do it?
