This year marks the 150th anniversary of the birth of the League’s first president and cofounder, Hiram Percy Maxim (HPM), W1AW. HPM was born on September 2, 1869.
As we have done with earlier birthday milestones, ARRL is again holding an operating event to celebrate HPM’s legacy.
Objective: This operating event is open to all amateurs, and the goal is straightforward: Find stations operating in the event, many adding “/150” to their call signs, and contact as many as possible during the 9-day celebration on each of the event bands (using any/all of the 3 event modes on each band).
Time Period: The 9-day event begins 0000 UTC August 31 and runs until 2359 UTC September 8, 2019.
Eligibility: All amateur stations may participate.
Who is eligible to use their “callsign/150”? W1AW and ALL ARRL members are eligible and will append /150 to their call sign during this event (this includes DX Stations who are ARRL members, who may operate as callsign/150 if permitted by the regulations of their country of license).
