Radio

You can talk to astronauts!

Ham

No, not the food, but a type of radio called amateur radio. (Ham comes from an insult meaning ham fisted operators because the smashed the morse code button) It is useful in many ways. You can rarely speak to people on the other side of the world. In emergencies when phones are down, roads are blocked and possible a flood, trusty ham radio will always work (if you don't run out of batteries) This is also what astronauts use and you can pick up their broadcasts at 144.49. Some schools talk to them.

CB radio

This should sound more familiar. This is Citizens Band radio and it's what truckers use. They can be used when you are on the highway and need information. I once heard somebody say that there was an accident up ahead and we avoided it. These are free to use and do not require a license. In the 70s truckers needed fuel for their trucks, so they used CB to find gas stations and this was also the oil crisis. their range varies based on wattage.
