A walkie-talkie refers to a portable radio. VHF range is usually 136 to 172 mhz and a portable will pick up if tuned to this range.

What humans use radio waves?

Radio waves are used to transmit signals from a radio station, and you can receive the signals with a radio, and hear them as sound such as speech or music. The long wavelength of radio waves makes them a suitable medium for transmitting over a large range. it is also use in agriculture...... it is used to diagnose different diseases

What type of electromagnetic wave is the largest?

The section we call 'radio'. Of course, there's no end to the electromagnetic spectrum, at least not on the low-frequency end, so there's really no such thing as "greatest" wavelength. As frequencies go down past radio and below, wavelength just keeps getting longer ... the bit of radiation from the 60 Hz utility power lines has a wavelength of almost 5,000 kilometers ( ! ! ). But we don't use anything down there in the form of radiation ... antennas would need to be gigantic in order to be the least bit efficient ... so there's no popular name for the radiated form. The 'generic' answer to the question is: The type with the lowest frequency.


Do computers use radio waves?

Absolutely. Computing is highly integrated into radio frequency (RF) type communications. Examples of RF integration include Bluetooth, WiFi, and RF peripherals such as the mouse and keyboard.


Can you use a cb radio antenna for am-FM radio?

Sure, you can use it; but it might not do a very good job. If you're listening to AM, you're receiving between 0.5-1.6 MHz, whereas FM is coming to you at 88-108 MHz. The CB antenna is designed to be resonant at 27 MHz.

What are some common uses of VHF?

Some of the most common uses for VHF is television broadcasting, FM radio broadcasting, the use of land mobile services which can be used for businesses, military and many other reasons.


Can a CB radio pick up VHF radio signals?

No. The old Citizen's Band (CB) consists of several skinny channels between 27 and 28 MHz, and that's where the receiver part of a CB transceiver operates. "VHF" is technically the range of frequencies between 30 and 300 MHz.


What does vhf and uhf mean?

Very High Frequency and Ultra High Frequency. They are ranges of frequencies of radio waves in the electromagnetic spectrum. VHF ranges from about 30MHz to 300MHz, UHF is from about 300MHz to 3GHz. They are further subdivided into bands for; marine, amature, and other 2 way radio use, also designated channels for television and radio broadcast stations, as well as other uses throughout the world. In the US on the now defunkt analog television system VHF channels were 2-13 UHF channels were 14-83.


Do miltary aircraft use vhf?

Almost all military transport and patrol aircraft use VHF.


What type of wire should you use with a vhf marine radio?

50 ohm RG8 or RG213 coax and don't skimp on the connectors - gold plated


When making vhf radio calls to nearby stations what level of transmitting power should you use?

Low power of course. You are NEAR the other station, why would you use "high" power?


How can the transmission distance be increased?

Use LF or lower HF frequencies (rather than UHF or VHF), proper SWR tuning of antennas, radio amplification.


What is communication system of the aircraft?

Generally speaking, VHF or UHF radio. VHF is also used to communicate with ground personnel (heli logging, SAR, firefighting, etc). The 'system' consists of a radio, antenna cable, and external antenna. an intermediate antenna switch can be used to allow multiple radios of the same band to use the same external antenna.


Why do uhf and vhf relate to television broadcasts?

Early television broadcasts were transmitted on VHF (very high frequency) radio channels. They moved to UHF (ultra high frequency) and have remained on that band since. These bands are used for terrestrial broadcasts. Satellite broadcasts use even higher frequencies.


How do you indicate if your boat is in distress?

To indicate that your boat is in distress, you can use visual signals such as displaying a bright orange flag or a square flag with a black ball. Additionally, you can use sound signals, such as repeatedly sounding a horn or whistle. If equipped, you can also send a distress signal via radio using the Mayday call on VHF Channel 16, or activate an Emergency Position Indicating Radio Beacon (EPIRB) if available.


What is an advantage of a cellphone over a VHF radio?

While both use high frequencies that are line of sight range only, the cellphone connects to a cellular network of transceiver antenna towers that are interconnected (via either landlines or microwave links) permitting cellphones at practically unlimited distances to communicate. VHF radios can only communicate when they can "see" each other (or both can "see" the same VHF repeater).
