Edward P. Thomas, Jr., the original W5JXP and now a Silent Key, received his Amateur Radio license from the FCC in 1939 at the age of 15. He joined the U.S. Army Air Corp in 1942 and was stationed on Guam in 1944 where he flew in a B-29 Super Fortress serving as the radio operator. At the end of WWII when the US ham radio ban was lifted, he and other hams stationed on Guam convinced the Army to let them build a ham shack which they used to relay 3rd party messages for fellow GIs. His son Daniel later took over the W5JXP call sign in 2026.
