To that, I would say take a chill pill. I'm an electrical engineer, and you would be surprised how many electrical engineers don't work on things "hands on". Yep, they may have their master's degree or PHD in electrical engineering, but give them a circuit board and a handful of parts, ask them to wire up a circuit and they would have no idea. Chances are good they don't know how to solder, or how to use a digital multimeter. Maybe they could analyze the schematic of an Astron RS-35 and know how it works, but ask them to troubleshoot one that isn't working and they probably would not be able to. So, cut him some slack, passing the FCC license exam does not automatically make one an electronic technician. Thank you to the OP for his service, and hopefully he can make some progress on the supply.
