Default KNX 1070 exhibits severe motorboating at night

I suppose I can try KNX this morning, but I don't see any reason for
IBOC to cause motorboating. Granted IBOC sucks in many other ways, but
it should not have such an effect on the analog signal.


It's part of the IBOC signal. If you have selectable single sideband
listen to any HD AM station, one sideband only; you'll hear it quite
clearly. It's a warbling signal at approx. 400 Hz.
