*NO!!!* The microHAM USB III is, in part, a USB to Serial converter.
It provides the CAT connection to the transceiver and should be treated
as a computer serial port. The RS232 connection should *NEVER* be
attached to a "listen only" port on a "Y" cable.

SteppIR controller.)

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?
