And my knowledge was limited lol. I don’t know exactly how bus systems communicate, my knowledge was limited to dc systems but not communications over them. The family business I worked in was split in half between 2-way radio and pager techs and the Chrysler Electronics warranty department I worked in. Me and my brother repaired Chrysler vehicle electronics for 7 western states - stereos, clusters, BCM’s etc. There were 3 techs that repaired my dad’s communication equipment that was in half the businesses in Portland and half the state up on mountain tops. Those guys were the real nerds. Radio frequency communications was pretty cool to me but to work on that required a degree. We had some of the first vehicle cell phones/ 2-way radios before cell phones were a thing. I did the installations for them in the vehicles and climbed the towers. It was a good job except I had to work for my dad and you know how that goes. I actually just came in to remodel the shop and ended up a tech after showing a knack for it lol. Long post, off topic but I don’t get much chance to reflect on those years.
