How to Peak and Tune a CB Radio

A CB radio (citizen band radio) is that type of radio which transmits signal that are coming from other CB radios. Using the mechanism of Amplitude Modulation (AM) it sends and receives various type of signals.

 It became famous at the time of 1970s. But even now some hobbyists use this CB radio. It is mostly used in trucks nowadays. It is also hooked up in some cars also. However, you can make a CB radio of your own if you want to. And here I have put the step by step instructions so that you can build a very powerful CB radio to use.

Installation:

CB radios are actually no longer in fashion, but if you want you can buy one from the electronics hardware stores. You may also find it in the truck shops too. CB radio is the priority of your shopping in this case, but you should pick up some other stuffs as well.

  • Radio: you need to buy the radio itself. It is usually 4 watt and sometimes a microphone will also come with free.
  • Antenna: Antenna is the most important thing in this radio setup. Fiberglass antenna is the most preferable because it is easily tunable.
  • A SWR Meter: It the part through which you can correctly measure the output given by the radio. It is very important because checking if you are getting the desired output or not is important.
  • Coaxial Cables: A coaxial cable is also needed to connect the antenna to the radio. You will require another cable only if you wish to hook it you the SWR Meter.
  • Batteries: Batteries are required for the power supply.

Now, you may be confused how you will hook up your SWR Meter. Don’t worry. I have come up with those instructions too.

You should hook the SWR reader like an adaptor between the radio and the antenna itself. You should check if the reading is as low as possible. Generally, the reading of 2.0:1 is quite a good reading and it is acceptable.

Now, you should know how to set up the antenna. Antenna is typically very easy to mount on a car. You will maximum the possibility of range capture if you just set it in the highest place. This makes the antenna able to receive the strongest signal very easily.

 Now that you have placed it in the highest place possible. Your next job is to connect it with the radio. Do it through the coaxial cables. You can also attach the quick release system and that would allow you to easily move or stick it in the place easily.

Now you have to alter the antenna as best as possible. Because tuning the radio means altering the antenna. Sometimes, it is required to adjust the antenna to make it able to get the best possible signal.

Test the Radio:

Check the SWR radio so that all the channels are getting the equal share of signal. Then you can assure that the frequencies are perfect by doing a test run in the channels.

Optimizing the CB Radio: 

Follow the owner’s manual so that you know every adjustment is done as it should be. Now I am going to give you some quick suggestions to make the peak of your radio. Before that, you need to make sure that you know all the basics.

If the radio is manufactured recently, then you should not require to peak it. Newer models don’t have the problem of drift and adjustment issues. Find an open area. If you can possibly take the device to an open are to do the check then it is the best. If you properly test and tune then you will have the least amount of signal noises.

Link SWR Meter

To check precisely connect you SWR Meter and you can do it through the coaxial cables.

Now you need to check the modulation. It can be done using the body of the CB Radio. Tweaking and Modulation is very preferable way of checking the output power.

Adjust the Quelch Range: 

It is the background noise cancelling function. You can do it using a nobon the body of the CB. Adjust is to the point where the noise is in the minimum level but the voice is still untouched.

Go to a store for doing the task of peaking. Check the internet reviews of the store before you give them your radio. Because all the store are not expert in handling the CB type of radio.

Then you have to test you radio using another CB radio. You can set the same channel and then check how your transmission is working.

This was pretty much how you should tune and peak your CB radio. And it is very much important that you take special care of the radio. Because it is reported that the type of CB radio often requires extra cautions while handling it.
