Thanks Claudio. Yes, the WLW HD signal is a problem on 690 kHz. IBOC
reminds me of the Soviet jammers I heard in Europe in the sixties. After my listening session this morning I swear the entire band is
being jammed. My ears are still ringing. It may be the way of the
future, but it's not a very well thought out system.
Have a very merry Christmas.
