[Elecraft] P3-switching between 2 K-3s

[Art KZ5D]

Hi all,


Trying to maximize the use of my one P3 by switching between 2 K-3s.  I use 2 separate switch boxes-one for the RS232 serial cable and one for the if cable. I use a Y connector onthe RS232 out from K-3. One side goes to the switch box, the other goes to computer for N1MM control.


All works fine EXCEPT I am unable to select Fixed Tune mode in the P3. It works fine using Tracking mode, but I prefer Fixed Tune mode.




Any suggestions?
