MFSK16 is particularly advantageous in weak signal environments because it uses multiple frequency shift keying, which helps improve the signal's resilience against noise and interference. This digital mode is designed to operate effectively even when the signal quality is not optimal. By utilizing multiple tones, MFSK16 can maintain readability and accuracy, allowing operators to communicate effectively even if the signal is weak.

This characteristic makes it a preferred choice for conditions where other modes might struggle. While options like higher speed or narrower bandwidth could be advantages of other digital modes, MFSK16’s ability to perform under adverse conditions without relying solely on error correction adds a valuable layer of effectiveness in challenging communication scenarios.
