The W1HP Philips Amateur Radio Club, originally the Hewlett-Packard ARC, has a history rooted in Andover, Massachusetts, as an employer-sponsored club. It evolved from a "full-service" club to primarily a Field Day club, maintaining its focus on this major annual effort. The club has participated in Field Day under various configurations, including W1HP/1B in Arizona, and has partnered with K1KKM and utilized GOTA stations like K1KKM and KD1NA. Recent Field Day operations reflect adaptations to changing circumstances, with members operating individually due to COVID-19 and later under "new" ARRL rules, sometimes as a "distributed" club. The club's constitution is also referenced, providing insight into its foundational structure. This page is maintained by W1DYJ, with a last update noted as 9 December 2025. -
