Loki5ace version 5.3.39.1 is a freeware amateur radio logging program designed for Windows operating systems (XP, Vista, 7) and compatible with Linux Wine. The software offers multiple installation methods, including a portable version (loc5portable.zip or Loce5pack.zip) that does not require administrator rights or Windows Registry modifications, making it suitable for USB stick deployment or limited user accounts. An official installation (loc5acest.zip) is also available, typically installing to C:\Program Files\Hamlok\LokiAce\ and requiring administrator privileges for initial setup and updates, with user-specific settings and database files stored in application data folders. The program's database, Loc4ac.mdb, can be renamed to the user's callsign for personalization. Loki5ace supports context-sensitive help, which requires WinHlp32.exe installation on Windows Vista and 7. The software includes features such as special print functions, Telnet Watch with comment display, and an 'Own QTH' field for location management. Updates can be performed via an in-program function or by manually copying the Loki5ace.zip file, which contains the main executable, Loki5ace.exe, to the program folder. The latest version 5.3.39.0 includes repairs for special prints and enhancements to the Telnet Watch feature.

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.
