The invention of the radio, the technology that harnesses the power of radio waves to broadcast signals, has allowed us to communicate using cell phones, watch television and even use the GPS navigation system. The importance of radio communication simply cannot be overstated. Some devices using radio technology are used less frequently than the others but that doesn’t mean they are not as useful. Here we will take a look at some devices that might seem obsolete to some but still hold great value.
Ham radios are wireless devices that use radio waves for communication. They are also called amateur radios due to the fact that when they were first invented, over a hundred years ago, they were used by amateur radio operators (not receiving any monetary compensation) rather than professional ones. They are most often used by hobbyists who engage in communication with other owners of ham radio.
To broadcast your signal using a ham radio you need to have a valid license from the Federal Communications Commission which is the governing body in the United States. Upon receiving the license you will be issued a call sign which is how you identify yourself when broadcasting. If you just want to listen to different broadcasts, you can do so without the license.

Ham radios are devices held in high regard by doomsday preppers. In case of emergency, system overload and subsequent failure to communicate is very likely with landlines. They can use a wide range of frequencies and can be used to communicate with emergency services as opposed to only listening to broadcasted information. If anyone you know also owns a ham radio, they can be used to communicate wherever you are. For people who live in areas that often flood or affected by hurricanes, it is a good idea to equip your family with ham radios on their own, even if it’s just for emergencies. The overall cost of the radio and the license shouldn’t be higher than $50 and they can save your lives.
A completely different type of device than ham radio, a stereo receiver is a combination of a radio receiver and an electroacoustic amplifier. It used to be the central component of many home theater systems but is now losing its popularity to other devices, such as soundbars.
A stereo receiver is a versatile device capable of receiving audio and video signals from a multitude of sources, including radio signals, DVD and Blu-ray discs or video game consoles. It will then process, decode and transfer that signal further to the TV or the speakers.
Modern stereo receivers are still evolving. They can connect to WiFi, play music from Bluetooth devices and even use music streaming apps. To know which is the best stereo receiver, have a look at online reviews. They often offer the same features as soundbars but are most customizable and allow you to build your home theater system just the way you want it.
