Proper installation of your CB radio is essential to reduce noise interference. While the widespread use of 24V/12V converters has reduced noise issues significantly, it is still important to have a professional CB radio installer handle the setup to ensure that all necessary tests are performed to minimize interference.
If your transceiver continues to experience excessive noise, follow these steps:

  1. Identify the Source of Interference

Determining the source of interference helps in selecting the most effective solution. Common sources include the power supply, antenna, or truck engine:

  • Power Supply: Connect the radio's power supply directly to the vehicle’s battery, keeping cables away from potential noise sources. Observe whether the interference improves or worsens.
  • Antenna: Disconnect and reconnect the antenna to check if the noise level changes. If interference is affected, try repositioning the antenna or replacing it with a different model. For optimal performance, we recommend using a President antenna with our President radios. Also, check out the CB Antenna section.
  • Truck Engine: Test the radio while turning the engine on and off. If interference decreases when the engine is off, the noise may be engine-related.
  1. Use Noise Filters

If the source of interference cannot be identified, or the above steps do not resolve the issue, consider using built-in or external noise filters.

Many of our radios feature built-in ANL/NB/HiCut filters. Test whether enabling these filters reduces or eliminates interference. If your radio lacks these filters, you can upgrade to a model that includes them or purchase third-party add-on noise filters designed for CB or car radios.

  1. Add Ferrite Cores to the Power Cable

If interference persists, consider adding ferrite cores (also known as ferrite beads) to the power cable. These components help suppress electromagnetic interference and reduce noise.

  1. Test Another President Radio

Install a different President radio without additional filters and compare interference levels to determine if the issue is specific to your current unit.

  1. Seek Professional Assistance

If the problem persists despite following these steps, consult a local CB radio shop or reseller for expert assistance. See our list of resellers and CB shops in the US and Canada.
