The callsign and the Mustang are some real treasures. If you had just gotten both ! Hi
Best of luck.
Mike, I'm next in line to be the caretaker (note I didnt use owner, as it will own me, not the other way around) of the Mustang.
I remember grandpas radio room in the basement, he had a big tower with a horizontally polarized directional antenna outside. He had no microphone, he was strictly CW guy. I remember large cabinets reading "Danger High Voltage" on them. Probably wasnt that big, but to a small kid, it looked like it. And I remember the constant "time", ie "at the tone, 1600 hours, 22 minutes, coordinated universal time, beeeeep......" every minute, it would play followed by a tick tick tick till the next minute expired....
He went to Skageway Alaska back in the early 20's after the war (he was Navy), built one of the first radio stations up there. Went back to Seattle, worked for a huge radio station till he got on for Boeing, where he worked in the radio/electronics (probably more like electrics back then) This was around the 30's, ie early. He retired there. I have 2 of his letters of recommendation from the radio stations when he was trying to get on at Boeing dated 1927 and a picture of him getting a 25 year pin from Boeing.
