In a transmitter operating on higher output power, what likely happens to surrounding receivers?

In a scenario where a transmitter operates at higher output power, surrounding receivers are more likely to experience interference. The increased power can result in the transmitter's signal overpowering the signals that receivers are trying to pick up from other sources, especially if they are operating on similar or adjacent frequencies. This phenomenon occurs because the stronger signal can mask or drown out weaker signals, making it difficult for receivers to effectively distinguish between the intended transmission and other signals.

In contrast, while it's true that receivers can receive stronger signals as a result of the increased output power of nearby transmitters, the primary concern in this scenario relates to the potential for interference. Higher output power can also impact the quality of the communication by causing audio distortion, saturation of the receiver's front end, or increased noise levels.

Therefore, the most characteristic effect of a higher output power from a nearby transmitter on surrounding receivers is the likelihood of interference rather than mere changes in signal strength or receiver output like S-meter readings or output increases.
