Rule Differences from WPX SSB/CW Contest
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 mode:
No 1.8 MHz operation
QSO alerting assistance is allowed in all categories, i.e., there is no Single-Op Assisted category
Single-Op 30-hour limit (vs. 36)
- Different-country contacts within any continent (not just North America) get 2 or 4 points
- Same-country contacts get 2 points on the low bands
"Call Areas" and Certificates
In the results, some call signs have a portable designator added when none was used in the contest. For example, KY0W sends that call sign when operating from California. However, in the results listing his entry is shown as 'KY0W/6' because he operated from the US 6th call area. This is done to clarify that KY0W's results are grouped with all others in his category from US call area 6 solely for the purpose of certificate awards.
Certificates are awarded by call areas in these seven large countries. "Call areas" generally conform to the ten numerical call areas, 0-9, but in some cases there are groupings where there isn't an explicit numerical call area. Two examples of this are in Canada where, for CQ certificate purposes, Canadian call area 1 is defined as the prefixes (and, multipliers) east of VE2, i.e., VE1, VE9, VO1, VO2, and VY2. Canadian call area 8 is similarly defined as VE8, VY0 and VY1.
These assigned call areas are only for the purpose of certificate awards. Prefixes are independently defined in the Prefix Multipliers section of the rules. Logs are checked using the call signs actually sent during the contest.
While primarily an amateur radio contest, WPX RTTY is also popular with SWL enthusiasts. Thanks to Marek, SP7DQR, who has written SWL log check software and to Dan, I1-12387, who will lead the SWL log checking.
