- This has been our main club call for many years. It was previously held by Wilbur C. Lauridsen, who was the first member of PAARA to lose his life in WWⅡ. According to a letter to the PAARAgraphs editor in the March 1985 issue written by PAARA member Vance Wardlow, W6FLE, “He lived in Palo Alto (on Ramona St.) and was a member of the Naval Reserve Security Group Number Five. I [Vance] was the C.O. of this unit, we had headquarters at Stanford’s old ‘Wood Perker Hall’ (ex womens Gym). In early 1941 Wilbur was called to active duty and was assigned to a Naval Security Unit stationed on Corregidor, P.I. He was there at the time of the Japanese invasion. He escaped by ship to Indonesia. From there he was assigned to a Unit in Australia but his ship was sunk by the Japanese in Suribya Straights. It was a Dutch cruiser. The Club asked to be assigned his call sign after the war and FCC agreed.”

- Used for our main Field Day stations. We applied for this when we wanted a better callsign for use on Field Day, and chose it because of the suffix (Amateur Radio Association, get it?), but it also turns out that it is the callsign of a former PAARA member—Jerome F. Zobel, W6ARA, of Palo Alto. I think I recall knowing this at the time, but I just rediscovered it going through a membership database book from the 1980s. (de K6WEB)
