For more well-rounded transmit audio, start
the transmit bandwidth at 3.0 kHz (3000 Hz).
The ORION default value for this setting is
3000 Hz.

The next control to adjust is 

L.F. Rolloff

,

also found in the SSB menu.  

L.F. Rolloff

refers to “low frequency rolloff”.  This control
interacts with the 

TX Filter BW

 to determine

your frequency response.

For example, if the 

TX Filter BW

 is set to

3000 Hz, and 

L.F. Rolloff 

is set to 150 Hz,

the response envelope for your transmitted
SSB signal is a low of 150 Hz and a high of
3150 Hz for a total bandwidth of 3000 Hz.
Using the same 3000 Hz 

TX Filter BW

setting, if the 

L.F. Rolloff

 is changed to 50

Hz, the response envelope is now a low of
50 Hz to a high of 3050 Hz, for a total
bandwidth of 3000 Hz.  You can think of the

L.F. Rolloff

 control as where the “bass

response” from your voice and the transmit
bandwidth is attenuated.

The next control to adjust is transmitter
equalization.  TX EQ can be used to give
your audio more bass or treble response at
a given transmit bandwidth and low
frequency rolloff setting.  It can also be used
to compensate for a microphone with more
bass or treble response.  ORION is provided
with audio equalization for the transmitter.  It
enables tailoring audio frequency response
for greater effectiveness and to
accommodate your preferences.  The TX
EQ establishes a specific audio profile for
your transmitted audio from either the MIC
or AUX audio input sources.  The TX EQ
effects from high pitched at –20 dB to
essentially flat response at 0 dB to very
bassy at +20 dB.  It is adjustable in 1-dB
steps.

Refer to Figures 4-3, Figure 4-4, and 4-5.
They illustrate responses in the center and
at the extremes of the equalization controls.
