CLUSTER, BUT MANY ALSO MANUALLY INPUT SPOTS TO INTERFACES LIKE DX MAPS.
THIS ALLOWS SELECTION OF SPECIFIC WEAK SIGNAL MODES LIKE JT65 AND JT9 FROM
THE DX MAPS WEB INTERFACES, AND USING THE OPTIONS MENU, ONE CAN SELECT ALL

PRESSURE SYSTEMS AT MID LATITUDES.  THEIR CAUSE COULD BE LOWER ATMOSPHERE,
LOW PRESSURE SYSTEMS THAT WOULD DISTURB UPPER LEVEL TIDAL WINDS, CREATING
