My dad is WA2VQW, and my siblings and I grew up with the ham ethic of fixing everything and never giving up on solving a problem. He has fixed countless things other people threw away, and many more that we took to him and said, "Dad, I think there might be something wrong with this. Could we take a look?"
Just a few days ago, I explained to him how my Ultrafire RCR123A cells would not fit in the Inova T1 I bought, and how I was upset I would have to plunk down more cash for AW cells. In about two hours, we had the problem licked. We did the work in his shack, and I showed him the CPF thread about the T1. "How much time do you spend on that site?!", he asked.
He lives in that room, and my mother calls his radio his "girlfriend." ;-)
