Tone ON/OFF control
When the RF CTCSS ENCODER screen or the AF CTCSS ENCODER screen is displayed, the
tone is turned on or off by the orange [ON/OFF] function key.
If the CTCSS tone is ON and the Tx TEST, Rx TEST, Dx TEST or AF TEST mode selected, the
CTCSS tone will continue to be generated.
If the tones out routing has been set to give RF tones, this is provided by modulation generator 2.
The legend
--CTCSS-- will be displayed against MOD2 FREQ on the RECEIVER TEST or
DUPLEX screens. If MOD2 is selected, the CTCSS tones can be controlled by repeated presses of
the orange [ON/OFF] function key. If
MOD2 FREQ is selected, the CTCSS tone is still controlled
by the [ON/OFF] key, but if a frequency is entered using the data keys or if the variable control is
adjusted, the CTCSS tone will cease. It can then be re-started only when the
RF CTCSS
ENCODER screen or the AF CTCSS ENCODER screen is displayed.
If the tones out routing has been set to give AF tones, this is provided by audio generator 2. The
legend
--CTCSS-- will be displayed against AF2 FREQ on the TRANSMITTER TEST, DUPLEX or
AF TEST screens. If AF2 is selected, the CTCSS tones can be controlled by repeated presses of the
orange [ON/OFF] function key. If
AF2 FREQ is selected, the CTCSS tone is still controlled by
the [ON/OFF] key, but if a frequency is entered using the data keys or if the variable control is
adjusted, the CTCSS tone will cease. It can then be re-started only when the
RF CTCSS
ENCODER screen or the AF CTCSS ENCODER screen is displayed.
