DTMF Transmit
DTMF is most commonly used for automation systems and remote control. A common example would
be in amateur radio repeaters where some repeaters are activated by sending out a DTMF number
(1450Hz/1750Hz/2100Hz).
Press and hold [PTT] and [>] key to send the DTMF number you have programmed on the software,
and the "BEEP" sound can be heard.
