Among the numerous things ma has dumped my way in the “No where else to put but it’s *not* allowed to be thrown out” pile, containing all sorts of stuff, was the owners manual to my fathers CB kit.
The shocker? The freaking thing goes as far as including schematics for the radios internal Printed Circuit Boards (PCBs).
I’m used to the typical modern electrical device manual: ya know, the kind that’s written in 6 languages and tells you next to nothing interesting, other than silly warning labels.
