[Elecraft] PX3 / KX3 USB Problem

[David Ahrendts]

My KX3-PX3 (and KPA100) are connected to an iMac also. On the theory that it’s the KUSB cable, or the chip in the cable, try swapping the KUSB cable with another. Just a thought.
Sure sounds like a software switch somewhere.

Nothing has changed, from an operator perspective: the PX3 has been sitting on my desk, untouched since the last time I used it a day or so ago. Very frustrating and disappointing, as I was hoping to use these two units to operate Field Day this weekend. I can use the KX3 w/o the PX3, but it's not what I had planned. Maybe someone else will have an idea. If not, I'l call Elecraft on Friday morning.

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.
