23 channel. Nice. Almost looks like the one my friends' Dad had in his garage.
He'd turn it on with the radio when he was working outside. Had an antenna on a pole outside.
Except for me and my friends in High School who used them as a party line, I doubt he heard much other stuff. We were always on 21, and he had it on that or 17. I never saw him use it, but it did work, as my friend called me on it once when I was about to pull into his driveway.
My parents had the Radio Shack "base" 40 channel version with the only display on it being the channel number and a LED bargraph for "signal." They had it in the kitchen, then my Dad discovered the thing only worked more than a mile at night, so he uninstalled his mobile and it. I wound up with it in my bedroom, the mobile went into a box somewhere. When I left home I left it behind, who knows where it wound up.
I got my Ham ticket 2 weeks after graduating (well, I successfully tested) and had "hardcopy" by the time I left for tech school. When I got my first 2m mobile, the seldom used CB in the car left it and never came back. And that was it.
I'm guessing my parents yardsaled all that stuff. I think I gave away or sold for cheap my stuff as well.
