Thanks Mike,
I'll pass on to Brian. Brian does have some engineering experience hanging around with me. He was involved in the Empire State Building antenna project working for an engineering firm I was working for at the time and we needed weekend engineers to shut off TV/FM transmitters on the building for the tower reinforcement project ,so I taught him and we hire him at 19 working overnight with other engineers from CBS/ABC.
At 19 he was in control of the FM combiner room for all the FM stations in NYC on the weekends and switching them to the Alford antenna from the main and firing up AUX TX's and in control of Channel 25 WNYE. What a rush for a kid. Brian has gone far from my expections and I'm glad I took him under my wing at 13 and brought him to work with me on the weekends.
A bench engineer like myself who can fix or build just about anything is gone with the new generation. It's simply a throw away world or buy a new one or send back to the factory.
