I got out of the industry a long time ago. I had an offer from CBS but really wasn't interested. I had a couple years experience working working at a small time station part time in the summer. I held a first class radiotelephone license since I was 16 and the chief engineer at the station was in management at CBS so I had a door opened for me. The life expectancy for engineers in that field was not too good. The transmitter I ran was an old RCA BTF-10 with a phased locked loop. The tuning capacitor for the oscillater was driven by a motor which got its feedback from a discriminator circuit. There was a backup unit that was crystal controlled but the thing was phase modulated and wasn't as good of quality audio even with the pre emphasis circuit in place. I got a whole two bucks an hour for running that station at night.
