What is peaking and tuning a CB radio?
When you purchase a stock CB radio from a CB shop most of them will offer to do a “Peak and Tune” for a extra fee. 3) The shop will adjust your power output so that your radio has a legal 4 watt deadkey and is reaching an acceptable level of peak output with modulation. …
How can I make my CB radio more powerful?
There are several procedures for ensuring maximum output.
- TUNE THE RADIO. A CB radio is only as good as the coax and antenna connected to it. …
- USE CB-SPECIFIC ANTENNAS. …
- ESTABLISH A GROUND PLANE. …
- CHECK THE VSWR. …
- ELIMINATE RESISTANCE.
How do you tune a CB radio with a SWR meter?
Turn the radio to channel 1. Key the microphone (depress the button and hold it). Turn the knob on the SWR meter labeled “SET” or “ADJUST” until the needle reaches the setting position at the end of its range. While still keying the microphone, flip the switch on the SWR meter to the “REF” or “SWR” position.

How far can you talk on a CB radio?
CB radios have a range of about 3 miles (4.8 km) to 20 miles (32 km) depending on terrain, for line of sight communication; however, various radio propagation conditions may intermittently allow communication over much greater distances.
What is CB dead key?
Dead Key is a carrier. It is a signal you put out when you key your radio and do NOT modulate.
How far will a 4 watt CB transmit?
Usually less than 15 to 20 miles mobile to mobile depending on the local terrain. In many situations, even 10 miles may close to the limit of your range. With a beam antenna on a tall tower, that range can be increased to perhaps 25 or 30 miles, but not much more than that.
Does coax length affect SWR?
Many antennas have a SWR of just over a perfect match like a SWR of 1 to 1.2. This is measured at the antenna itself. With a length of coax the SWR will now show a SWR of say 1 to 1.0 , because of the loss in the coax. And so will the bandwidth change a little.
What is Dynamike on a CB?
Setting Squelch and Dynamike
Squelch eliminates or reduces noise in a CB radio when you tune the receiver to an unused frequency. Turning the “Squelch” control counterclockwise allows all of the signals in.
Can SWR be too low?
An SWR too low over the whole band (1:1 for all 40 channels) can indicate a low efficiency antenna or lossy component. … If you have an antenna that’s say, three feet or less, and the SWR tunes great (less than 1.5) across all the channels than maybe your antennas feedline coax or the antenna coil is “lossy”.
Why can’t people hear me on my CB?
Make sure the connections are tightened. Ensure that the microphone pins on the radio are making a connection with the microphone plug. … Be sure you are pressing the CB microphone button all the way in. If it is a power mic or echo mic, make sure there is a battery in it!
What is RF gain on a CB?
What is RF Gain on a CB Radio? RF is used as a synonym for “radio,” in this case a CB radio. … To counteract noise, RF gain acts as a sensitivity filter. It reduces noise in the receiver without reducing reception power as a CB radio squelch does.
