I forgot to mention you have to kill KX3 Utility before starting PX3
Utility. You can't have more than one program using the same serial
port at the same time.

Jim,
I would try the following troubleshooting procedure:
Connect the "XCVR" ACC1 RS-232 jack on the PX3 to the ACC1 jack on the
KX3. Turn them both on. If the KX3 and PX3 work normally together (PX3
reads KX3 frequency on the screen, etc.) then the "XCVR" RS-232 port on
the PX3 must be OK.
Now connect the PC to the "PC" ACC1 RS-232 port on the PX3 and turn off
the PX3. If KX3 Utility can connect to the KX3, then the cables and
connectors must be good.
Now "without touching anything" turn on the PX3. If:
- KX3 Utility can't connect to the KX3 and
- PX3 Utility can't connect to the PX3,
then it sounds like the "PC" RS-232 port on the PX3 must have died somehow.

Have a KX3 and PX3 that have been working fine - until this morning.
Today I am unable to have the KX3 connect to my computer if the PX3
is powered on. If I turn off the PX3, the KX3 serial - USB
connections works fine. As soon as the PX3 is powered on, the
connection goes away. I'm using Elecraft-supplied cables, not
off-brands. The PX3 Utility cannot connect to the PX3 with the KX3 on
or with it off. Other than the connection to my iMac being hosed, the
PX3 and KX3 appear to be working just fine.
Any suggestions how to determine what's going on?
Tnx, Jim / W6JHB
