29: Listen to CB radio
After I looked into the low frequencies yesterday, let's go to a higher band again: The Citizens Band!
This is the third frequency band I'm aware of where anyone is allowed to transmit – provided that you use a licensed device!
This is a band where my random wire antenna really comes in handy. Without it, I would have a hard time understanding anything. And even with it, transmissions are extremely noisy.
CB radio is used internationally, especially by truck drivers?
