Reminder: the Candian province of Ontario now consists four RAC sections: Ontario North (ONN), Ontario South (ONS), Ontario East (ONE) and the Greater Toronto Area (GTA). Make sure your contest logging software and "country" (CTY) files have been updated so that those abbreviations are recognized and credited properly. View a map of the VE3 sections.

Operating Guideline: You must include your call sign in the exchange information you transmit to the other station. This is generally done between your precedence (A/B/Q/M/S/U) and your check (year of first license) as follows:

CQing Station: CQ Sweepstakes from W9JJ
Answering Station: W1AW
CQer: W1AW 123 A W9JJ 79 CT
Ans: 43 M W1AW 31 CT
CQer: Thanks, CQ Sweepstakes from W9JJ

As the answering station, it is not necessary to send the CQing station's call unless you feel there might be some confusion about what station you are responding to.
