From what the OP wrote, I don't think he's using the Tune button to
activate the KAT500.
A 3rd party sells a cable that plugs into the AH-4 socket on the back of
the IC-7300, which allows you to make the IC-7300 enter Tune mode, by
pressing the simple button on the end of the cable. It would of course
be possible to make your own.
