Using Subaudible Tones
Some repeaters require you to transmit a subaudible tone to acti-
vate them. You can set your HTX-242 to transmit any of the 38
standard subaudible tones. You can also limit incoming reception
by setting the HTX-242 to open the squelch only when someone
transmits a subaudible tone you select.
Valid Subaudible Tones
Setting the Subaudible Tones
Some repeaters require you to transmit a subaudible tone with
your transmission. You can also set a tone that must accompany
transmissions for your HTX-242 to open squelch.
Follow these steps to set the subaudible tones for the VFO mode.
After you set the tones, you must activate the function to turn it
on. Changing this setting does not change the tones stored in any
memory channel.
