After a variable filter (
Var 1
,
Var 2
) has been shifted you can use the
IF
→
V
button to
translate a filter shift to a new VFO frequency (see the VFO Controls section on page
71)
Res:
Returns the
Shift
control to the default middle position and restores the filter to its
original position (i.e. before the
Shift
was used).
When the display is set to Panadapter, the mouse can be used to directly adjust the selected
variable filter (
Var 1 or Var 2
). To do so right click with the mouse on the Panadapter display
until no cross- hairs are showing. Then click on the filter and drag it to shift the filter as a whole
or click on a band edge and drag it to adjust the filter bandwidth.
The
Var 1
and
Var 2
filters are saved just like the labeled filters and are mode-dependent (i.e. you can
save a different
Var 1
filter for
LSB
than for
AM
). Hotkeys are available in the Setup Form-Keyboard
Tab (described on page 123) to change the filters using the keyboard.
(8) Mode Specific Controls
This section of the front console displays key controls specific to the selected modulation mode. There
are three sets of controls: Phone, CW and Digital.
Phone Controls
The phone controls, shown below, are available for all phone modes (LSB, USB, DSB, FMN, AM and
SAM). Most of these controls can also be found on the Setup Form-Transmit Tab (see page 111, where
a more detailed description may also be found)

Mic Gain:
adjusts the software microphone gain. This is a simple multiplier applied to the input
samples when in transmitting. The control can be adjusted using either the slider or the text
box. Note that increasing the MIC Gain control will also raise the amount of noise in the signal.
A hardware preamp will give the best performance for amplifying microphone signals. Having
said that, the software gain works very well in many setups. Voice modes are typically
optimized when the peak reading on the TX Mic Meter reads just below 0dB (see page 54
above)
DX:
click to enable the DX compander (a form of compression), which has been optimized to
give your voice an extra punch, especially useful in DX situations. Adjust its level with either the
slider or the text box.
