HyperLog is an Amateur Radio logging program designed to make the Hams" life easier by organiz- ing contact, WAS, WAZ, and DXCC information and displaying it in an easy to read format. It also displays other help- ful data on screen during a QSO. The program provides previous contact retrieval using a very fast B+ tree indexed search technique and displays these contacts in a scrolling window on the main screen as well as a full screen complete database browser. Bearing and distance details are provided by decoding the prefix of the call sign to determine the country or state and then looking up the correct latitude and longitude coordinates in a table. These coordinates, as well as your local coordinates, are then fed to a Great Circle calculation routine to obtain bearing and distance information
