To Peak and Tune a CB radio, you will need a CB Radio SWR Meter. Make sure you are a far from buildings and power sources as possible, then connect the SWR to the CB and go to channel 1, then set it on SET. Key the mic and adjust the SWR until the needle reaches the highest point. Next set the meter on REF and write down the numbers. Use the reference point to tune your other channels.
