Experimental high power IBOC operation

Exactly right, Len14043. I have the advantage/disadvantage of EVERY station, HD or analog, being distant from me, save for one 100KW blowtorch here in Wilkes County, NC. I'm sure there are compromises involved in the adoption of FM HD. EVERY TIME YOU SHOEHORN A NEW SERVICE INTO EXISTING SPECTRUM WITHOUT TAKING AWAY ANYTHING, THERE'S A COMPROMISE! FM Stereo, Color TV, AM Stereo, SCA, and now HD Radio involved compromise, in that something was lost (noise performance, coverage area, interference, something) in exchange for what was gained. What was lost is obvious to me with other technologies (including AM HD, of course). It's just that with FM HD I'll be damned if I've heard any of this compromise. but again, of course my situation isn't typical...a rural location where the closest HD station I receive is about 30 miles away (Hickory NC) and the most distant, 100 miles away (Black Mountain/Asheville NC).

I still don't buy that FM IBOC does much damage to 1st adjacents. I am between WFDD, 88.5 in Winston Salem (non-HD), and WNCW 88.7 in Spindale NC (HD). I can easily get WNCW IN HD, with no interference from WFDD, and vice versa. Then I have a new antenna, rotor, and pre-amp...but a "serious dxer" would likely have proper gear as well!

I believe WNCW-HD is receivable at your location because their digital sideband is open on 88.9. Is that correct? If you had a station on 88.9, I doubt you would be able to receive WNCW-HD because both of their sidebands, i.e 88.5 and 88.9, would be obliterated. WMUB-HD in Oxford, Ohio at 88.5, about 25 miles distant, is receivable only in analog at my location because 88.3 and 88.7 are also occupied. WMUB's digital coverage is limited to about 10 miles due to the close spacing of signals on that portion of the band.
 
There is a station on 88.9, but I'll be damned if I know who it is. I'll listen for an ID. With my new antenna, there's someone on most frequencies now!
