What is a disadvantage of using mechanical modulators in FM communication?

In FM communication, mechanical modulators can present specific limitations related to their design and operational requirements. The selected answer highlights a notable disadvantage: mechanical modulators typically mandate the use of specific components, such as either a capacitor or a variable inductance microphone, to facilitate modulation. This constraint reduces flexibility in system design because it limits the variety of transducers or microphones that can be employed. Unlike electronic modulators, which can interface with diverse input sources, mechanical modulators' dependence on these specific components can hinder adaptability in various applications or conditions.

This specificity can affect both the performance and the scalability of communication systems. For instance, if a particular type of microphone is not available or not suited for a specific environment, it may restrict the effective deployment of the communication setup. Therefore, while mechanical modulators may have certain advantages in specific scenarios, their reliance on particular components can pose challenges in broader FM communication contexts.
