I have looked for a list and haven't been able to find one. I have read that there are a number of receivers that will decode both IBOC and C-QUAM. From my experience I know the RS Accurian and Sangean HDT-1 and HDT-1x decode both while the Sony XDR-F1HD and Boston Acoustics Receptor HD radio do not. My brother bought a JVC radio for his truck that has HD but it has one of those "T" shaped antennas in the windshield and I haven't been able to get enough of a signal from WLS, CFCO or KCJJ to tell if it decodes C-QUAM. Best Buy sells a Insignia HD Tuner that looks almost identical to the Sangean HDT-1x but I haven't heard if it will decode AM Stereo like the Sangeans do ( http://www.bestbuy.com/site/Insignia%26%23174%3B+-+HD+Radio+Stand-Alone+Tuner+-+Black/8910315.p?id=1217633559969&skuId=8910315&st=insigniahd tuner&cp=1&lp=1) My experience with HD radios that also receive C-QUAM have been the same as Powell's. While they receive C-QUAM, the bandwidth does not seem to open up like my Delco AM Stereo/FM Stereo receivers when receiving an AM Stereo signal. Dave in OH On Mon, Dec 7, 2009 at 11:33 PM, Powell E.
