Frankly, I miss the point in discussing his license class. In the past, I owned and operated two commercial communication stores/shops. About a quarter of the business was from the ham community. At that time, only one of my bench/field technicians was a ham--the remainder of us simply competent technicians and engineers. Several worked for radio and television stations--several others had been R&D staff in the aerospace industry. One was self taught, and held nearly a dozen patents for RF technology. But not a ham... The ability to buy, repair/rehab and sell ham equipment is not contingent upon license class. Some of the finest service technicians and RF engineers I have met did not have a ham license or had a "mere" tech license. Some of the most intelligent and electronically competent people around only possess Tech licenses. Class is not germane to the conversation.
