[Elecraft] K3, KPA500, KAT500 interactiions

[Ron D'Eau Claire]

Right. My mistake. The underscore does not appear. The asterisk *does*
appear when the key line is grounded, enabling the KPA500. So the asterisk
should *not* appear while the KAT500 is tuning. 

If Bill sees the asterisk while the KAT500 is tuning, the KPA500 is not
inhibited which will cause the KPA500 to fault.

In the standard configuration, the KAT500 does not explicitly inhibit the
KPA500 - rather it interrupts the keying line (by opening relay contacts).
My setup is remote, so I can't confirm this, but the underscore should not
be displayed in this case.

This does require keying to be routed through the KAT500, using the ACC
cables, and no other keying path should be in place (e.g. RCA direct from K3
to KPA500).
