WTEL 610 Philadelphia was overmodulating by 200-300% for a good year or
two before they finally fixed it. I complained - never got any
response. Using 110+ khz bandwidth on peaks.
Now they finally stopped and stopped using IBOC so I'm very happy.
I'm guessing lots of automated stations make mistakes all the time.
What they need is an automatic error checking system (ex. if your audio
modulation is below 10% for more than 2 minutes or if your frequency
drifts by more than 100 hz, it could trigger a text message). Though
from my experience as a software developer, even with error checking it
is hard to maintain 100% up time.
