A retiree from World War II is being called back into service on a historic Vancouver site.The radio transmitter building is two miles away from Pearson Field. Seventy years ago, they both were part of Vancouver’s sprawling U.S. Army base, although at opposite ends. And that was the idea. According to a U.S. Army history of defense installations, “In all cases, radio buildings were located at a distance … so that radio operators received minimal disturbances in sending and receiving messages.”People who want to contribute to the museum effort can call the VA’s Anne Marie Murphy at 360-737-1441.The assignment? Showcase some of that history.The project involves a modest brick building in the northwest corner of the Vancouver Veterans Affairs campus. It was built in 1940 as the radio transmitter building for Pearson Field. Now volunteers, including members of a local military heritage group, are working to create a museum that also will honor veterans. It’s in an appropriate location, next to Spanish-American War and Korean War memorials, and near the Huey helicopter — visible from Interstate 5 — that is part of the Vietnam War Memorial Garden.There are some gaps between those eras. Museum organizers plan to fill in the gaps with displays and artifacts representing those who served in World War I and WWII.The building itself is one of those artifacts. The radio transmitter site is one of only three structures on Vancouver’s VA campus dating to World War II. The others are a gymnasium and a former patient ward converted to office space. The museum site is the only one of the three that was designed to be a permanent building.
