The audio on Newsradio 1080 KRLD has become hard to listen to. In the last few weeks it has started to sound like it is being fed to the transmitter by an old analog telephone line and the sound is overmodulated or something. It's a little better on my HD radio when the HD kicks in, but still doesn't sound good at all. I don't notice this problem on any other AM station. Anyone know what's going on?
