What radio frequency are walkie-talkies?
Two-way radios (or walkie-talkies) generally operate in the 136 MHz to 900 MHz frequency range, as defined by the FCC. This is an overview of the various services and bands of frequencies. For a complete guide to all the officially assigned frequencies, you can refer to the FCC Online Table of Frequency Allocations.
Can you use a radio to communicate?
They are Ultra High Frequency (UHF) radio and Very High Frequency (VHF) radio. Neither frequency band is inherently better than the other. They each have their pluses and minuses. Both formats are effective ways to communicate with another person so deciding on the right radio for you depends on your application.
Can VHF talk to walkie-talkie?
Firstly, the radios need to be ones that use the same basic frequency band. Most “business” or “consumer” walkie-talkies will work on either the UHF band (400 – 470MHz) or the VHF band (136 – 174MHz). It is not possible to get a VHF radio to “talk to” a UHF radio.
How do you end a radio transmission?
5) Use “CLEAR”, “OVER”, “OUT” when you finish your message. It notifies the addressee that you finished your portion of information and wait for the response or just ended the transmission (“OUT” word).
Are ham radio conversations private?
Amateur radio is not suitable for the use case you are describing, and a mobile phone is. Private from your neighbor, maybe. Not necessarily private from from your telephone provider, government, and anyone who does business with them.
How far can you talk on the radio?
Arguably, the biggest factor that determines how far you can talk on the radio is the frequency you’re operating on. Here’s a chart that shows the radio spectrum and all the different frequency bands that are available to amateur radio operators: Amateur radio operators can transmit on frequencies as low as 136 kHz and as high as 250 GHz.
What are the radio frequency bands?
Radio Frequency List. Common radio frequency bands include the following: AM radio – 535 kilohertz to 1.7 megahertz. Short wave radio – bands from 5.9 megahertz to 26.1 megahertz. Citizens band (CB) radio – 26.96 megahertz to 27.41 megahertz. Television stations – 54 to 88 megahertz for channels 2 through 6.
What is the frequency range of a two-way radio?
The two most commonly used frequency ranges for two-way radios are VHF (Very High Frequency 130-174MHz), and UHF (Ultra High Frequency 400-520MHz). Unlike frequencies below 2MHz, radio waves in these higher frequencies travel in straight lines (called “line-of-sight” signals), and generally cannot travel beyond the horizon.
What is the UHF radio frequency?
The UHF radio band for commercial radios is between 400 to 512 MHz. Until recently, it wasn’t widely used. Now, the UHF radio frequency is used for two-way radios, GPS, Bluetooth, cordless phones, and WiFi. There are more available channels with UHF so in more populated areas UHF may be less likely to have interference from other systems.
