        Ok, I made those settings on the second computer, the Dell, and
        the signals toggle just as you said. The only thing I did
        differently this time was to "click" on <Initialize> on all
        three screens. Whatever the reason it is working and I can
        proceed with the transmit audio. I'll have to make a switch for
        ptt. I should have the required DIN connector in a few days,
        it's in the mail.

        Next to do the same to this computer, it should work the same.

        It's set to use Pulseaudio and I've been setting audio levels
        with "Pulse Audio Volume Control."

        Thanks much for the help and encouragement.
