Updated: January 29, References. CB or Citizens Band radio is a type of radio that transmits signals on a channel shared by other CB radios. It transmits and receives using Amplitude Modulation AM.
Their use and popularity peaked during the s, although they're still used by hobbyists today. However, with a basic antenna setup and some thoughtful tweaking, you can have a powerful CB radio for use at home. A CB radio transmits signals on a channel shared by other CB radios.
You can optimize your CB radio by setting it up correctly and adjusting the settings. Use the coaxial cables to connect the SWR and antenna to the radio so you can receive and transmit signals, and set up your antenna somewhere high to maximize your range, such as the top of your car or house. Once your radio is set up, adjust the center modulation knob to increase your range without distorting the sound of the radio. Then, adjust the squelch knob on the left of the radio to reduce background noise so your signal is clear.

This technique offers many advantages, such as an excellent square wave response from DC to over KHz. Also, the pulse width, or duty cycle, is precisely controllable assuming that you are using a function generator that has this capability.
The only disadvantage is a peak output power reduction from 16 watts to 4 watts, but a volt power supply can be added to the system to bring the peak power levels up to about watts instructions at bottom of this page. If you are not at all handy with a soldering gun, though, you might want to seek the help of someone who is.

For clarity, I have capitalized the functional name of the component leads. Good luck! It is lying flat on the board. Cut the resistor's right-side lead as flush with the board as you can or desolder it from the bottomthen lift the resistor up on its left lead at a degree angle. Using your solder gun, heat the top side front-left corner of L2's shield and place a bead of solder there.
Hold the 2N horizontal in your left hand with the flat side printed side facing up and the leads facing to the right. Solder the Emitter lead of the 2N to L2's solder bead that you just made. Solder the Anode of the diode to the solder bead on L2 and solder the Cathode band end to the Base lead of the 2N Solder one lead to the Base lead of the 2N Solder a 6" length of 20 or 22 gauge stranded hookup wire to the other side of the 10K resistor. It is labeled "TF".

Ok, well if some do 2. I never cut diodes or do mods that will mess up the clean sound of a transmitter. I don't mess with any of that stuff, just want a nice clean sounding radio, the purpose was to ask what others' put out, so now I know.
The cheap little workman meter said 2. MOct 2, Last edited: Oct 2, Outlaw CBOct 2, I carry one of those radios the Pro XL in each car in a zippered tool bag with a cigar lighter plug as a spare in the trunk, just in case everything else in my vehicles goes belly-up or if I find myself caravanning with someone unexpectedly who doesn't have a radio, etc.
I've also got a couple as loaners in case someone has to get on the road before I've got time to troubleshoot and repair a radio properly, or if a radio needs parts I don't have on hand.
When I benched the ones I've got here, but without doing anything to them except restoring the clipped limiter I found on one, all of them were dead keying between 2. I still think a awful lot of "swing" can be attributed to the mechanical momentum of a needle's mechanism that can't stop moving up as quickly as the level that was driving it that way stops; that's why I like a scope, and a fixed tone to give me an average level. I challenge any indifferent, critical listener to detect a difference on the air between any of these and one that's putting out 8 to 10 watts of "swing".
My station rigs all have low pass filters that I have inline all the time, just on good engineering principles. View attachment LPF always a good idea.

The good news is that this article will walk you through the process of properly tuning your antenna a.
Assuming that everything else in your system is properly installed, the only additional equipment necessary is a short length of coaxial cable known as a jumper leadan SWR meter, and something on which to record your readings.
The objective behind tuning your antenna is to make these two readings as close as possible.
Getting down to a 1. There are two basic points to understand before adjusting the length of your antenna:. If your antenna is too longit is necessary to reduce its physical length. There are several methods for shortening an antenna which vary by manufacturer. If your antenna is too shortit is necessary to increase its physical length. Most instances where the antenna length is too short are caused by a lack of ground plane.
In modern antennas, there's usually a method for adding length built in to the antenna. Other options, such as adding a spring, are also legitimate. Dual antenna installations : If you're tuning dual antennas, you'll want to adjust both antennas the same amount each time. As a starting point, it's best to put the tuning screw either all the way in or out, so each antenna is the same length. Re-measure SWR and continue to re-adjust as with a single antenna, making sure to make incremental changes that are as close as possible to both antennas.
Readings on both channels that are less than 2. If readings on these channels are in the red zone on your SWR meter or above 3. This problem must be remedied before attempting to use your radio. By following the steps outlined in this article, you should be able to successfully tune your antenna for optimal performance and transmission.
Learning Center About Us.If you are looking for a basic radio with no frills attached to it that is affordable, easy to use and install, then I recommend the Uniden PROXL Channel CB Radio as it is still working perfectly in my vehicle when traveling. This past Christmas I went to visit my family in Indiana, you know how the roads are over this time the year being cold, and snowing at times well my CB Radio that I have owned for more than seven years decided to die on me. While visiting I thought to myself, I need to buy myself a new CB Radio for the road trip back as I have gotten so used to having one in my vehicle.
Thinking back to when I bought the Uniden PROXLit was not that expensive and I was not looking for a radio packed with the latest technology, as I did not see myself using all the features and a waste.
I only required a basic radio with no frills attached. The box itself contained the PROXL, the microphone and hook, a mounting bracket, the knobs, and mounting hardware. The radio was easy to install and required no adjustments and reading between and The big test came on my way back home and was quite surprised that I could reach users up to 5 miles that were superb!
Regrettably, on the way back home the semis that passed by forced me to remove the antenna as it nearly blew away. The first thing I had done when arriving home is to take my radio to a friend of mine and had it tuned and peaked for me and now able to get 14 watts out of it instead of seven and can transmit up to 20 miles while traveling. What I love about this radio is that it is packed full of the basic needs and the knobs are easy to use and each one provides its own functionality.
The front of the radio consists of a PA switch that you can use as a Public Address system for those who would like to use it in a workshop that I off course would never use.
The CB comes with 40 channels and consists of emergency channels to the police, fire department, and, of course, the weather information. It offers you with a direct CH9 switch directly switching over to the emergency nine channels. They offer you with more than customers who have bought the range of Uniden CB radios.

Also, you can add a CB spring to the antenna and mount to provide limited flexibility if desired. Wilson Flex : On the trail, it's convenient to have an antenna that can survive getting snagged, bent, bowed and abused.
Subsequently, we picked an antenna that can bend degrees without breaking: the Wilson Flex. These 3' and 4' antennas provide superior protection against snapping and hold up well to the rigors of off-road use. While flexible, they don't offer the same level of transmit and receive performance that a traditional fiberglass antenna like the Firestik FS does. If flexibility is most important -- and long-range communication isn't crucial -- the Flex is a good choice.
We include a choice of six mounting kits for a great deal of flexibility and customization. All kits include a quality CB antenna mount and a high-grade CB coax cable.
