Stew Perry TopBand Challenge


This is a 160-Meter DX grid square contest. The contest exchange is your 4-digit grid locator. 

QSO points are based on the distance between the center of the 2 locators. Count 1 point for each QSO up to 500kM and 1 point for each additional 500kM distance. ex: 1750 kM = 4 points.

A power multiplier is used instead of grid multipliers. The multiplier for high power (B) is 1. If you use 5 to 100W (A), the multiplier is 1.5. Less than 5W (Q), the multiplier is 3. 

Click the [ Multi/Bonus ] button to setup this multiplier. Then re-load the log file to update the score.

The total score is QSO points  X  power mult.

As of 2003, the 599 RST defaults are used in the Cabrillo file format, even though not exchanged.
