CUSTOMIZING TRANSMISSION SIGNAL
CHARACTERISTICS
The quality of your transmission 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 transmission signal.
■

TX Filter Bandwidth (SSB/ AM)

Use Menu No. 25 to select one of the following TX
low-cut filters: 10, 100, 200, 300 (default), 400, or
500 Hz.
Use Menu No. 26 to select one of the following TX
high-cut filters: 2500, 2600, 2700 (default), 2800,
2900, or 3000 Hz.
■

TX Filter Bandwidth (LSB-DATA/ USB-DATA)

Use Menu No. 27 to select one of the following TX
low-cut filters: 10, 100, 200, 300 (default), 400, or
500 Hz.
Use Menu No. 28 to select one of the following TX
high-cut filters: 2500, 2600, 2700 (default), 2800,
2900, or 3000 Hz.
■

TX Equalizer (SSB/ AM/ FM)

Use Menu No. 30 to change the transmission
frequency characteristics of your signal. You can
select from 1 of 6 different transmission profiles
including the default flat response. Selecting any
of the following items from the Menu causes
" " to appear on the display.
• Off (oFF):
The flat frequency response for SSB, FM, and
AM (default).
• High boost 1 (Hb1)/ High boost 2 (Hb2):
Emphasizes higher audio frequencies; effective
for a bassi voice. High boost 2 does not reduce
the low frequency as much as High boost 1.
• Formant pass (FP):
Improves clarity by suppressing audio
frequencies outside the normal voice frequency
range.
• Bass boost 1 (bb1)/ Bass boost 2 (bb2):
Emphasizes lower audio frequencies;
effective for a voice with more high frequency
components. Bass boost 2 emphasizes more
low frequency response.
• Conventional (c):
Emphasizes by 3 dB frequencies at 600 Hz and
higher.
• User (U):
Reserved for the optional ARCP software.
Off (oFF) is programmed at the factory as a
default.

TRANSMIT INHIBIT

Transmit Inhibit prevents the transceiver from being
placed in transmission mode. No signal can be
transmitted when this function is ON, even if Mic [PTT]
is pressed.
• TX Inhibit OFF: Transmission is allowed.
• TX Inhibit ON: Transmission is not allowed.
Switch this function ON or OFF via Menu No. 60.
The default is OFF.

BUSY LOCKOUT

Busy Lockout prevents the transceiver from being
placed in transmit mode if the current operating
frequency is busy; in other words, if the squelch is
open, you cannot transmit.
• Busy Lockout OFF: Transmission is allowed.
• Busy Lockout ON: Transmission is not allowed.
Switch this function ON or OFF via Menu No. 74.
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 transmission mode.
While transmitting, if you select a frequency outside
the transmission frequency range, the transceiver is
automatically forced to return to reception mode.
