Case 2: Transmitting by the External PTT connected to a D-sub connector
If the External PTT is connected to all RF Decks, each RF Deck transmits individually.
If the External PTT connected to the D-sub connector of the Selected RF Deck is operated, the behavior is the same as
that of Case 1.
If the External PTT connected to the D-sub connector of an Unselected RF Deck is operated, the Unselected RF Deck
transmits, and the “TX LED” icon appears alongside of the transmitting Unselected RF Deck on the display of KCH-20R.
