subaudible tone at the same time as it transmits (TX) or receives
(RX) a regular signal. This special tone lets you listen only to oth-
er transceivers set to the same tone frequency when you use the
transceiver in simplex operation. It also lets you match your trans-
ceiver to the subaudible tone frequency used by a local repeater.
