Digital voice signal report alternative

There’s a new alternative way of signal reporting for amateur radio digital voice transmissions called Mean Opinion Score or MOS.

On the MOS scale 5 is excellent, 4 good with impairment perceptible but not annoying, 3 fair and slightly annoying, 2 poor and 1 bad, with zero meaning the signal is unusable.

MOS should be very useful as a signal reporting method for digital voice transmission by radio amateurs including
D-STAR and P25.
