September 26-27, 2015

Starts: 0000 GMT Saturday
Ends: 2359 GMT Sunday

Identical wording is used for both the RTTY and CW/SSB rules where the intent is the same. However, there are some key differences for the RTTY:

  • No 1.8 MHz operation
  • Multi-Single:
    8-band-changes per clock hour, rather than a 10-minute rule

  • Contact points:
    -  Different-country contacts within any continent (not just North America) get 2 points
    -  Same-country contacts get 1 point

  • Third multiplier for QSOs with US/VE stations
