For CB's that are both modern and "legal" a frequency counter does not help much at all. However if you have an older radio with continuous tuning (dial with a needle) or are tuning "out of band" (using an illegal modified CB) you may find a frequency counter very useful. No,All the frequency counter does is match the frequency to the radio, to tell you how accurate the radio is, if it is a quality radio it is a waste of time for a more efficent CB radio you would want a RF meter to match the antenna to the radio, this would give you max signal when you key the mike, most of the radios that I have ever used have a signal strength right on the radio. All radios are designed to reject all frequencies except the one it's tuned to. Transmitter accuracy and receiver accuracy are both important for clear reception. CB radio uses 26-27 Mhz with a channel spacing of only 10Khz. If your transmitter's frequency is 5Khz too high and the person you're trying to talk to has a receiver that is a few Khz too low, you may not be able to talk to them at all or the sound will be distorted. All radios can be aligned. Better quality radios will not necessarily hold that alignment better. Antenna matching will affect how strong the signal is but not the frequency accuracy of that signal.
A frequency counter will tell you what frequency you are on. It does not help the average CB radio. But it does do a lot for modified cb's with extra channels. A Frequency counter also comes in handy if you are talking on side band, it helps you remember where to set the dial, and makes tuning someones signal in much easier. A Frequency counter will help if you need it. If you dont need it it is a waste of money.

When you use a radio telescope what happens?
You are receiving that portion of the electromagnetic spectrum that radios use. It is a much lower frequency than visible light and can detect things that glow at much lower temperatures than stars ... such as gas clouds Many radio telescopes use the 'hydrogen line' at a wavelength of 21 cm. That is one of hydrogen's spectral lines, corresponding to a transition between two high energy levels in the hydrogen atom.
Why FMCW radar has better range resolution than CW radar?
FM CW radar sweeps the Radio Frequency over time. Time in Radar equates to range and results in a high spectral density at every range. CW radar has a much lower spectral density and does not code range with frequency in the same way.
What is the envelope of a signal?
The envelope of a signal is the "apparent" signal seen by tracking successive peak values and pretending that they are connected. Normally, this question involves amplitude modulation of a radio frequency carrier by an audio frequency signal. The two frequencies involved are very much different - 20 kHz versus 1 mHz, for instance, and this "envelope" effect will be very noticable on an oscilloscope.
How much money did Talk Radio gross worldwide?
Talk Radio grossed $3,468,572 worldwide.
How much money did Radio Flyer gross domestically?
Radio Flyer grossed $4,651,977 in the domestic market.
What is the sentence of the frequency?
I would very much like to see you with greater frequency. What frequency will you be on? I can switch to another radio station by adjusting the frequency of my radio receiver.
What type of electromagnetic wave is used for television?
Radio waves. A bit higher in frequency than "radio", but not much.
Which has a higher frequency gamma rays or radio rays?
Gamma rays have a much higher frequency then radio waves.
How does sputnik affect the people around it?
Not much. It wasn't radioactive, it couldn't do much but beep on a radio frequency.
Do am radio waves have a lower frequency then ultra violet radiation?
Radio waves and ultraviolet waves are the same physical phenomenon.The difference is that radio waves have a much greater wavelength.(That's equivalent to saying that they have a much lower frequency.)
The main difference between a radio wave and a light wave is?
The difference between a radio wave and a x-ray is the fact that x-rays have a much higher frequency. Since higher frequency means more energy in electromagnetic waves, x-rays can be used for purposes such as taking photos of things inside the body. Radio waves are at a lower frequency and have a much longer wavelength. They are used in radio, television, and communication.
Types of radio waves?
Both gamma rays and radio waves are part of the electromagnetic spectrum, but gamma rays are much higher frequency (shorter wavelength) than radio waves. Visible light is lower frequency than gamma and higher than radio.
Do radio waves have a high frequency?
Because the X-ray has a shorter wavelength (kuch shorter!) the energy is much greater in an X-ray. Therefore with a bigger energy, E = hv would calculate a higher frequency for x rays. As the eregy of a wave increases, so goes the frequency. Actually, it probably should be stated the other way, but I still have answered your question
What is an rfid chip?
The RFID chip is a Radio Frequency IDentification chip. When it receives a radio wave in the right frequency range, it sends back a characteristic radio signal which allows it to be specifically identified, much like a bar code would when optically scanned.
How does the frequency of radio waves compare with the frequency of visible light?
The radio wave part of the spectrum is very wide. The extreme ends are, roughly,15km ( used for communicating with submerged submarines)1 mm ( used for research, and possibly for radar)The visible spectrum covers only a 2:1 range of wavelengths. It is centred on the colour yellow, with a wavelength ~= 700nm.The very shortest of the radio waves is about 1000 times as long as yellow light.
Indicate some significant differences between broadcast radio and microwave?
a microwave requires a much higher frequency
Light waves are the wavelengths that register on your visual receptors Radio waves have a much slower wavelength and not as much energy?
Radio Waves are lower frequency/longer wavelength. Don't know about energy level...
