Which of the following can reduce overload of a VHF transceiver by a nearby commercial FM station?

Installing a band-reject filter is a practical solution for reducing overload of a VHF transceiver caused by a nearby commercial FM station. A band-reject filter, also known as a notch filter, is designed to attenuate signals within a specific frequency band while allowing signals outside that range to pass through unaffected. In the context of a VHF transceiver, if a commercial FM station is operating at a frequency that overlaps with the operating frequency of the transceiver, a band-reject filter can effectively eliminate or greatly reduce the unwanted signals from the FM station, thus preventing them from causing interference and overload.

This solution is particularly effective in environments where strong unwanted signals are present and can significantly improve the performance of the transceiver by maintaining clearer communication. The other options listed do not specifically target the problem of frequency overlap, making them less effective in addressing the overload from a nearby FM station.
