Radio transmitter interference happens when your radio picks up unwanted transmissions from a nearby CB, Amateur or two-way radio station. This happens because your radio is unable to reject radio transmission occurring on other frequencies. Because of the cost, it is usually impractical to improve the ability of the receiver to reject unwanted transmissions. Sometimes the transmissions are picked up in the audio or power leads. Your will probably need to consult a technician for advice about filtering.
Radio and television retransmissions services sometimes operate in areas or pockets of poor reception to extend the coverage of national, commercial or community services. The ACMA has the discretion to make spectrum available for retransmissions under sections 34 and 212 of the Broadcasting Services Act 1992.
