Power for 12 Volt CB Radios

For years I've done this in three different ways.

  • Use a 12 Volt battery [either a spare automotive battery, or a smaller motorcycle battery, or a gel type battery scrounged out of an automatic emergency light fixture that someone has discarded in a dumpster].
  • Another method is to use a high quality AC powered battery charger. The reason that the high quality is the need for a "steady" rather than fluctuating voltage. A cheap charger can be used IF a battery is used in parallel to act as a "buffer" to reduce voltage fluctuation, and it will keep the battery charged as well.
  • I have also used a test/workbench "regulated power supply," set for the voltage and current requirements for the radio.

WHAT IS CB Radio?

A CB radio is a wireless transceiver that operates on the frequency band called Citizen Band, CB. This band has been reserved for the public. In some countries license is required and in some countries no license is required to operate CB radio. The maximum power limit is 5 Watts. There are 40 channels around 27 MHz in this band.


How much power does a galaxy hl88 put out on high power?

The Galaxy HL88 is a CB radio that typically outputs a power of around 40 watts on high power. It is designed for use in the Citizens Band radio service, which is limited by regulatory standards. Users should ensure they operate within legal limits to avoid interference and comply with regulations.


Does a frequency counter help a cb radio that much?

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. ~TeZ~


If you made a 14V 150mA solar charger for your cigarette lighter why would the radio turn on when plugged in with no ignition movement?

The radio shares the same power as the cigar lighter. When car is off neither work. Putting power into the plug fires up the radio. This means that using a solar panel to keep the battery up will not work on this car w/o putting the lighter power feed onto a battery supply fuse at the fuse panel.


Where is the positive or negative lead and the ground on a CB radio?

To get a positive you can go straight from the battery or the fuse box. To ground the CB you should ground it to the body being sure you have a connection to bare metal. A better way is to run a cable, along withe the positive side, directly to the battery. If you run power or ground to the fuse box and a short occurs, you may knock out important systems on the vehicle. Best go directly to the battery, with in-line fuses on both sides of the line.

Can you plug a CB radio into a standard wall outlet?

No, CB radios are typically powered by a direct current (DC) power source, such as the vehicle's battery or a separate power supply designed for the radio's voltage requirements. Plugging a CB radio into a standard wall outlet, which provides alternating current (AC) power, would likely damage the radio and pose safety risks.


Can you use a cb radio with a 12 volt regulated 5 amp power supply?

Yes, you can use a CB radio with a 12 volt regulated 5 amp power supply as long as it meets the voltage and current requirements of the radio. Make sure the power supply can handle the CB radio's power consumption to avoid damaging the equipment. Additionally, ensure that the power supply is of good quality and can provide stable power output to prevent any interference with the radio signal.

How do you increase cb wattage?

To increase CB (Citizens Band) radio wattage, you can add an external amplifier specifically designed for CB radios. This amplifier will boost the output power of your radio and effectively increase the wattage. However, it is important to ensure that you are in compliance with legal power limits set by your country's regulations.

Can a CB radio cause problems with VoIP?

I do not see how a CB radio could interfere with VoIP service. If the CB radio is creating interference on the line, check your telephone. Or even check your broadband modem to ensure that you are not creating packet loss due to the CB radio.


How does a linear for a cb radio work?

Transmitting over four watts on a CB radio is actually illegal, thus, using a linear amp on a CB is illegal, as well. A linear amp attached to a radio (for argument's sake, we'll assume it's on a type of radio on which the application is legal) simply amplifies the power output. The radio transmits into the amp, the amp amplifies the signal, and transmits it to the antenna.
