CUSTOMIZING TRANSMIT SIGNAL
CHARACTERISTICS
The quality of your transmitted signal is important,
regardless of which on-air activity you pursue.
However, it is easy to be casual and overlook this fact
since you don't listen to your own signal. The
following sub-sections provide information that will
help you tailor your transmitted signal.

Changing Transmit Bandwidth (SSB/AM)

Use Menu No. 22 to select one of the following
transmit bandwidths: 2.0 kHz, 2.2 kHz, 2.4 kHz
(default), 2.6 kHz, 2.8 kHz, or 3.0 kHz.
B a d n w d i h t
2 0 . k H z
2 2 . k H z
2 4 . k H z
2 6 . k H z
2 8 . k H z
3 0 . k H z
1: If the Speech Processor is ON, the low-cut filter is set to
200 Hz for 2.8 kHz and 3.0 kHz.

Equalizing Transmit Audio (SSB/FM/AM)

Use Menu No. 14 to change the transmit
frequency characteristics of your signal. You can
select from one of six different transmit profiles
including the default flat response. Selecting any
of the following items from the Menu causes "TX
EQ." to appear on the display.
• Off:
The default frequency response for SSB, FM,
and AM.
• High boost:
Emphasizes higher audio frequencies; effective
for a bassy voice.
• Formant pass:
Improves clarity by suppressing audio
frequencies outside the normal voice frequency
range.
• Bass boost:
Emphasizes lower audio frequencies; effective
for a voice with more high frequency
components.
• Conventional:
Emphasizes by 3 dB frequencies at 600 Hz
and higher.
• User:
Reserved for future use. Off is programmed at
the factory as a default.

TRANSMIT INHIBIT

Transmit Inhibit prevents the transceiver from being
placed in transmit mode. No signal can be
transmitted and receiver audio is muted with this
function is ON even if the PTT or [SEND] is pressed.
• TX Inhibit OFF: Transmission is allowed.
• TX Inhibit ON: Transmission is not allowed.
Switch the function ON or OFF via Menu No. 54. The
default is OFF.

CHANGING FREQUENCY WHILE TRANSMITTING

Moving your frequency while transmitting is usually
an unwise practice due to the risk of interfering with
other stations. However, if necessary, by using the
Tuning control you can change the operating
frequency while transmitting. You also can change
the XIT offset frequency while in transmit mode.
While transmitting, if you select a frequency outside
the transmit frequency range, the transceiver is
automatically forced to receive mode. If you selected
transmit mode by pressing [SEND], transmission will
not resume until you select a frequency inside the
transmit frequency range, at which time you must
press [SEND] again.
