This is the one thing I hate about communications sets, too many of the HAMs that owned them seemed to think that their license was equivalent to an engineering degree and made half baked mods. So they take a perfectly functional design and started screwing with things, drilling holes, adding switches, taking stuff out, second guessing the armies of engineers at the Hallicrafters/National/Hammerlund plants and rewiring them.
