Cobra MicroTalk radios are two way radios or walkie talkies that allow you to keep in contact with someone a certain distance away without making a phone call.
Short wave frequency has a shorter wave length. Frequency is defined as number of cycles per second. If you have shorter waves (measure from peak to peak) you can get more of these packed into one second, so the frequency is higher.
There are many types of emergency radios available. Some of the types of radio available include Ham radio, AM radios, FM radios, CB radios and walkie talkies.
The Bose corporation makes bose radios for your enjoyment. No other company makes the bose radios or any radios quite to their standard.
microwaves :)
Cellphones use microwave radiation to send and receive. Radios do the same, but with long wave or short wave.
The pop-up toaster, short wave radios, and arc welders were invented in the US in 1919.

Kenwood portable radios are radios which allow you to speak with people up to 5 miles away. They are very durable but can also be a little bit pricey.
Regular household AM radios pick up stations on frequencies between 550 KHz to 1.7 MHz . . . wavelengths between 176 meters and 545 meters. Regular FM radios pick up stations on frequencies between 88 MHz and 108 MHz . . . wavelengths between 2.8 meters and 3.4 meters. 'Short wave' radios, taxi radios, police radios, CB radios, firetruck radios, aircraft radios, weather radios, satellite radios, toy walkie-talkie radios, cellphone radios, computer WiFi radios, cordless telephone radios, garage door opener radios, Bluetooth radios, 4G iPad radios, and microwave oven radio transmitters all have their own separate frequencies/wavelengths that they operate on, so that they don't all interfere with each other.
In the USA, all of the NOAA National Weather Service weather-radio stations operate in the band between 162.400 MHz to 162.550 MHz. Standard AM/FM radios can't receive these transmissions, and neither can a typical 'short-wave' radio. Shop electronics stores, or on line for "weather radio".
The extent to which radios have impacted our lives is expansive. The radio was the first means of communicating verbally over vast distances in a short amount of time. Before, telegrams and handwritten letters were the mainstays of communication. It also furthered the development of Wave technology, which leads to television, and microwaves. in many ways, the modern world would not be the same without radios.

Short Wave Live was created in 1993.
An electromagnetic or a radio wave withwavelengthless then 100 meters called as Short Wave.
Short Wave on a Cold Day was created in 2001.
The Short-Wave Mystery was created on 1945-03-01.
