The color scheme and frequency ranges for the display of spots
on the main window and the Band Map is determined by the filter
which is selected. The user can create as many different filters
as are needed for different circumstances. The Filter Editor is
used to create and modify filters. Filter Editor Window Each
line (element) of the filter determines the color of the display
for spots falling in the range shown. If the filter is set to
HIDE then spots in that range will not be shown at all. There is
no limit to the number of elements any filter can have. Filters
can use many different colors so that adjacent spots in the Band
Map will be separated by band. Extra bright colors can be used
to make one or more bands stand out from the rest in the Band
Map or the main window. The 30 meter band will be shown in
orange in the example window. The frequency range of the
selected filter is shown at the bottom of the window. This is
especially handy when you have selected a font in the same color
as the background
