W1AW

W1AW is the call sign of the headquarters station of the American Radio Relay League (ARRL), the national association for amateur radio in the United States. Located in Newington, Connecticut, W1AW serves as a vital resource for amateur radio operators worldwide.

The station transmits code practice, news bulletins, and other information of interest to the amateur radio community. These transmissions are often used for practice in Morse code proficiency and to stay informed about ARRL activities, regulatory changes, and technical advancements in the hobby. W1AW also operates as a special event station during contests and other significant events in the amateur radio world.

The call sign itself is historically significant. It was originally assigned to Hiram Percy Maxim, one of the founders of the ARRL. Following Maxim's death in 1936, the ARRL petitioned the Federal Communications Commission (FCC) to have the call sign permanently assigned to the headquarters station as a memorial to his contributions to amateur radio.
