IARU Member Societies On-The-Air for IARU HF World Championship
In this weekend's IARU HF World Championship Contest, IARU Member-Societies from all around the globe will be active and operating with special call signs. According to ARRL Contest Branch Manager Sean Kutzko, KX9X, many of these call signs end in HQ, designating a national headquarters station; these can be worked as special multipliers in the contest. Kutzko said that IARU Administrative Council members will also be on and can also be worked for special multiplier credit: "If you hear a station giving R1, R2, R3 or AC as their contest exchange, that station represents part of the IARU Administrative Council or regional Executive Committee."
