I have a dozen or so DRM channels programmed into my SDR. Even a couple of MW AM ones.
And I tune through them every day or two.
The problem is that the performance of DRM is terrible. It takes a hugely strong signal before it is free of drop-outs, plus is very intolerant of any interference on the same channel. And of course drop-outs with DRM are very jarring, as they lock up the channel for many seconds.
When compared with a conventional AM Transmitter from the same city, at the same power, the AM TX is far more pleasant to listen to.
