Since December 2021, when 97.1 FM in Los Angeles dropped its top 40 music format and started simulcasting news with KNX AM, they switched off their stereo and have been broadcasting in Mono. Makes sense, news is all talk, why would they need stereo? But I was hoping that with the switchover to 97.1 The Fan last month, they'd perhaps turn the stereo back on.

But they haven't.

Now, I know the practical reason for this, an FM mono signal travels about twice the distance of a stereo signal, and can be picked up further away with better clarity. So, broadcasting in FM mono increases their potential audience.
