Static On The Line - 3000/3100

Because the CB3000, CB3100 are half-duplex, audio switching phones, hum and static can block audio by the duplex controller in one direction. The cause of the noise requires locating and resolving appropriately:

  • The noise may be internal to the CB enclosure.
  • High intensity lights may cause the noise. Check by dropping the power to the light and test the phone. If the noise is gone, replace the light.
  • Communication devices like cellular transceivers may produce noise on the line. The noise is the result of a weak transmission mode. Move the antenna for a better signal level or use a high-gain antenna.
If you find out that the light is the cause you may have a ballast going bad in the strobe and may need to replace it. If there is a phone line suppressor try bye passing that also to see if this clears the static and if so you may need a new one. Also check your connection for tip and ring which is on pins 3 & 4. Make sure that the phone  line isn’t directly touching anything that may cause interference.
