ARRL 10-GHz & up Cumulative Contest

Stations exchange six-digit grid squares. The signal report is optional. 

The 6-digit is used to calculate the distance (kM) between stations, for points. New versions of GenLog use [vhf4k.adi] for lookup. Enter the 6-digit if not found in the lookup file, or if the station transmits a different one. GenLog displays the heading and distance after the square is entered. If your antenna is calibrated to known beam headings (beacons) and you know the station`s beam heading from the 6-digit data, your chances of making a contact are greatly improved. Now you just need to have propagation and find his frequency. 

Notes: The 6-digit grid can be entered before making the QSO. A station can be worked more than once on a band if at least one station moved more than 16 kM / 10 miles.

When you move to another location, change the 6-digit grid in the TX Exchange window after loading a log file. When re-loading a log file, the last grid you made a QSO from is inserted into the TX grid field. The distance and beam heading to the station being worked (or to be worked) are calculated based on this entry.

Each new call sign per band scores 100 QSO points. 
1 QSO point per kM distance between your 6-digit and the 6-digit received.
Total score = sum of the QSO points plus the sum of the distances.
