Figure 40: Filter Setup Screen
On the left, select the
Mode
and the filter button to set the filter up for. Then on the right adjust its
settings. An indication of the filter is displayed in the lower section of this screen, which can be dragged
as a whole, or the edges of which can be dragged as an alternative way of adjustment. When done,
you can select another button and/or mode to change the filter for. When finished, just close the Filter
Setup Screen. To revert back to the default settings, right click on a filter button, select
Reset to
Defaults
and click
Yes
.
Note:
Although there are 3 groups of mode-dependent default filter settings,
you can customize the labeled filter for each mode independently. E.g.
you can have different filters for LSB and USB, for FMN and AM, etc.
Variable Filter Buttons
The variable filter buttons
Var 1
and
Var 2
offer two separate filters, each of which can be adjusted
with the

,
Width
,
Shift
and
Res
controls described below as well as the mouse. The
Panadapter display setting is good for visualizing changes to variable filter controls
Low:
Selects the low cutoff frequency for the filter. The value is the plus or minus offset from
the center frequency as shown in the VFO display. Note that in lower side band modes (LSB,
CWL and DIGL) this value can be negative.
High:
Selects the high cutoff frequency for the filter. Note that in lower side band modes (LSB,
CWL and DIGL) this value can be negative.
Width
: Widens the filter as the slider is moved right, and narrows the filter as it is moved left.
The behavior of this control is set in the Setup Form – General Tab, Filter Sub-Tab (page 70).
Shift:
Shifts the selected filter passband up or down from its normal center frequency. This can
help to eliminate interference caused by signals in close proximity of the received signal. The
behavior of this control is set in the Setup Form – General Tab, Filter Sub-Tab (page 70).
