Fixed-Signal Levels

The "colors" for the Fixed-Signal Level "ranges" are user selectable from this window. These colors are relevant only when the Coverage Map menu Prediction Options item "Fixed-Signal Levels" is checked. By default this item is not checked and therefore dB>uV coverage predictions sets use the gradient colors and ranges.

Use of this color selector is very much the same as others, such as the Amateur Bands colors. However, the level "ranges" are fixed and only the colors are adjustable.

To change the color used to indicate a range, click the colored rectangle located to the right side of the range label. The resulting color selection dialog is a rather standard windows dialog and is used through out this software for color selection. The user is free to experiment and discover the simple operation of the color selection dialog window.

If you make changes and later decide you do not like them, click the Reset To Originals button to restore the colors.

If you choose to use the Fixed-Signal Levels option, you will likely also wish to change the "coastline" and political boundary color so they can be more easily seen. To make such a change, access the Coverage-Analysis View menu, Map Options, Political Boundary Color item.

Below is an image showing a Coverage-Analysis View prediction set of dB > µV and the Fixed-Signal Levels option. This image also shows a "filtered" contest-log plot of one hour and one band. The image is smaller to fit help file and was saved using the Coverage-Analysis View menu, Map Options, Save As GIF function.

Below is an image showing the exact same Coverage-Analysis View and "filtered" contest-log plot. However this image was created using the standard "gradient ranges and colors" setting. The number of gradient ranges and colors is adjustable from three to twenty. This image uses the maximum of twenty. The default is seven gradient ranges and colors and provides more difference between each change. Note above, the "coastline" and political boundary color was changed so it can be more easily seen. To change the "coastline" and political boundary color, access the Coverage-Analysis View menu, Map Options, Political Boundary Color item.

We feel the default gradient ranges and colors is much more intuitive, readily learned or understood, than the Fixed-Signal Levels option. The reason is the "blue" color, cool, is the lower signals and the "red" color, hot, the high signal levels. Further, actual signal levels more likely vary gradually and not suddenly. However the fixed-signal levels provides a very nice display, as it's certainly easier to see the predicted level changes.
