Stewart,

The message really means, "Something of sufficiently low impedance to common is attached to the auxbus, holding the auxbus line at a logical low. Turn on the device if it is off -- this is the most common cause of the problem -- or disconnect the device from the auxbus."

The symptom first showed up consistently during KPA500 development, so the error message suggests turning on the KPA500.

In your case, I'd say, "Keep calm and carry on."

I have a K3 connected to an XV144 in the preferred configuration shown in the manual with the AUX port used for band switching.

Occasionally I find that with the XV144 powered down the K3 hangs complaining that the KPA500 needs to be turned on. I can cure this by powering on the XV144 or by disconnecting the Aux lead from the XV144.

Is this a fault on one of my component's (K3, cable or XV144), a bug or a feature.

Any idea where I should start to debug?

Thanks

Stewart/G3YSX
