9 TRANSMIT FUNCTIONS TX TUNING This function continuously transmits a carrier at a certain level of output regardless of the current transmission mode. This is useful for adjusting an external antenna tuner or linear amplifier. This function can be used by assigning the "TX TUNE 1" or "TX TUNE 2" function to a PF key on the front panel or a PF key on a microphone equipped with PF keys. Refer to "PF KEYS (PROGRAMMABLE FUNCTION KEYS)" for details on function assignment. {page 16-6} '

TX TUNING
This function continuously transmits a carrier at a certain
level of output regardless of the current transmission
mode. This is useful for adjusting an external antenna
tuner or linear amplifier.
This function can be used by assigning the “TX TUNE 1”
or “TX TUNE 2” function to a PF key on the front panel or
a PF key on a microphone equipped with PF keys. Refer
to “PF KEYS (PROGRAMMABLE FUNCTION KEYS)” for
details on function assignment.
