In the previous three installments, we tore down two old CB’s and an even older tube based CB linear amplifier. Those teardowns were a lot of fun and a great way to look at the way things used to be done before frequency synthesis took over.
In this final CB teardown, we’re going to look at one more old CB. Fewer details are available about this one, but let’s take a look at what we’ve got.
Examining the Radio
The radio itself is a Fanon Courier Cruiser. It’s a crystal controlled 23 channel radio typical of the era. According to the information in Popular Science’s November 1975 issue, this thing sold for $219.95. Adjusted for inflation, that’s an eye watering $1050 in today’s money! To put that in perspective, you could buy a Yaesu FT-818 HF/VHF/UHF All mode QRP radio, an LDG HF through 6m Auto tuner, and a 31′ Jackite Pole for portable operations- and have money left over!
- Disassemble in a logical order
- Don’t break anything out of impatience
- Be patient (see #2)
- Save all the parts
- Look for value in unexpected areas
- Respect quality

Some noteworthy items in this radio include some great looking knobs and switches, and the only socketed crystals in any of the CB’s I’ve torn down. Sadly, all of them are in the 10mhz (just outside of 30m) or 37mhz range, but perhaps something interesting can be done with them. The components are all high quality and show little sign of age. In fact, this CB was the least grungy out of all of them.
Why go to all this trouble?
Because we can. I personally find these teardowns to be therapeutic. There’s something about disassembling old electronics that takes me back to when I was a kid and would take apart anything I could get my hands on. I shudder to think of some of the things I destroyed, like my Dad’s reel to reel tape player. But I’d like to think that my methodical approach and appreciation for the engineering that went into these CB’s, the pinnacle of radio technology at the time, redeems me from some of my previous sins… Maybe!
I hope you’ve enjoyed this series. I’m planning one final article soon, where we look at what was gained from all 4 teardowns, how we might be able to use them for QRP, and how one of these radios has already contributed to my next QRP project!

What’s that colorful box?
In my posts I try to feature one little thing that’s been helpful to me in my ham radio experiments, and the little colorful box holding up the CB in the first few pictures is this guy:
It’s the SIQUK 1480 piece resistor kit. They’re just 1/4 watt resistors, but the selection is huge and there are 20 of them for each value. And the best part is that they are well labeled in individual baggies. Anybody who’s bought a giant stack of resistors to sort through knows what a slog that is. This Kit was the best value I found at the time, and I’m very happy with it so far.
Thanks for reading, and 73!
