It would seem to me if a tip is given as in the prior post by AT, to quote, "Settings >System >Channel >(unused Channel say "Ch7 AUXx:NULL") >NULL >SEL >[Channel Control Select] two position switch say "G" > SET. Return to main menu or turn Aurora off. " and that to get to the function on another radio the sequence is Settings>Model>Channel>(unused Channel say "Ch7 AUXx:NULL") >NULL >SEL >[Channel Control Select] two position switch say "G" > SET, that this would be the place to question whether that prior post. So I believe my question is still valid in this thread.
