This is a Beacons 'by-band' tab; obviously for
14 MHz. The waterfalls with the grayed out headings are data being
collected for beacons that may not be on the air (the user can set).
This view of the data shows "where in the world" conditions
support signal propagation for a given frequency. Across the bottom of
the display are the bearings and distances to the currently transmitting
beacon.
