If anyone can post an audio sample (with a link here) of an IBOC-AM

using an
average AM radio please do so.


Band-scans up and down across 930 WPAT's IBOC signal (notice how it
nearly obliterates 920 WPHY and hisses in the background of 910 WRKL
and 950 WPEN):

Thanks for the links, dude ;-), they were most helpful.

First-adjacents get the major step-on while seconds get their share of hash.

To be fair, much of the hiss (in regard to listening to 930) was on stereo
reception. In mono the hiss was less, but still annoying. It's a noisy
signal that a strong signal doesn't fix. And don't get me started on the
telephone tin-can quality of what's left of the analog signal.

920 & 940 were both obliterated, an inexcusable situation. The fact these
stations were receivable without analog interference from 930 suggests these
are receivable AM stations being jammed (ok, not intentionally, we'll say
involuntary stomping on). Wasn't the FRC (Federal Radio Commission,
predecessor to the FCC) formed to stop this kind of interference?

As stated before, this isn't IBOC but IBAC twice (an in-band adjacent
channel on both sides) with a hit to the main channel to boot (hiss &
reduced fidelity).

IMHO the only answer is for the FCC to allocate spectrum in the short-wave
band for DRM to replicate current AM service in digital. The FCC allocated
new bandwidth for FM, let them do the same for DRM.
