"Editorial on the recent approval of HD Radio (IBOC) in the USA"
http://www.am-dx.com/amiboc.htm
Someone just set this to me via email. Interesting to note, the author heard that Australia recently ceased digital broadcasting on AM, due to interference to New Zealand stations. The author offers three scenarios for the future of HD/IBOC - the most notable, that HD/IBOC will eventually be shut off to protect the analog signals, due to lack of consumer interest in HD Radio.
Also, this may be a better place to ask this again:
If I am equal-distant between two 50kw AM-HD stations, say 400 miles at 800 and 810 khz, should I be more concerned with their nighttime IBOC signals cancelling/interfering each other out, by the time the skywaves arrive, or should I be more concerned with a nearby 50kw AM-HD station on an adjacent-channel, interfering with the skywaves, as they arrive ? Anyone - thanks !
