  This option, when enabled, will do the following:  If listening to a chan-
  nel while in Scan Mode, or if in Scan Hang Time, pressing the PTT will
  allow you to transmit on that channel.  When disabled, pressing the PTT
  will allow you to transmit on the Priority Channel, if the radio is in the
  Priority Scan Mode; or will transmit on the channel you were on before the
  radio went on into the Scan Mode.
