[Elecraft] Need help with kat500 utility

[Andy Durbin]

"I  have some question about the operate tab in the kat500 utility.  In the "others"  what should be checked off?
"caps on the Ant side"
"amp key interrupt"
"attenuator"
  Not sure what these things do."

If you don't have a specific reason for changing these values you should regard these as status indicators rather that user control selections.

Cap side will be chosen automatically to achieve the best match.  It indicates whether the capacitors of the LC tuning network are on the transceiver side of the inductors or on the antenna side of the inductors.  It can be set manually when attempting to manually find, or improve, a tuning solution.

Amp key interrupt indicates that the keying line has been opened and a connected amplifier cannot be keyed by the transceiver.  It is set automatically in some fault conditions and when an autotune is in progress.

Attenuator is a mystery that Elecraft will not respond to.  It indicates that the KAT500 internal input attenuator has been activated but the removal of an internal KAT500 resistor that is part of this attenuator seems to make it impossible for the attenuator to work as designed.
