FM stays listenable even with heavy distortions when you drive out of range and you can decide for yourself when you no longer tolerate the signal. Digital doesn’t give you warnings and just goes silent
DAB+ receivers can (and many do) display signal quality. Not playing distorted, noisy signals is a feature I greatly appreciate.
Especially so with digital public TV. its absolutely unusable. and now they can't stand that people want to share sports broadcasts, so they are updating it again to add encryption. I can't believe anyone watches it.
In my experience DAB goes painfully 'squawky' and squeaky before finally cutting out, it's unbearable in headphones.
This video gives a good example of the signal breaking down from 00:38
