HD Radio/IBOC will fail - VERY few are buying HD radios, and the FCC
has not authorized IBOC for nighttime AM, so nothing to worry about,
yet. If you want to learn more visit:


IBOC DXing is rather fun. A real kick picking up an AM station broadcasting
IBOC at a small fraction of power relative to the analog main carrier in
digital sound. Having a DX station's call-sign displayed for instant
station verification is pure bliss.

So far my best IBOC dx catch with "instant verification" was about 500 miles
via grayline one morning. Keep in mind that until the analog broadcast
signal is turned off, the IBOC signal is transmitted at a small fraction of
the power that the main analog signal is broadcast. So any IBOC DX catch
made right now is indeed a remarkable feat. The night that AM stations
broadcast in 100% IBOC only with full legal power will really be fun.

There are a few AM IBOC stations that broadcast about an hour or so before
and after their local sunrise/sunset.

IBOC/digital DXing is no different than DXing other digital modes like CW,
RTTY, HDTV, etc... All the whiners are just concerned that they will have
to retire their analog R8 receivers along with their analog TV's to the
museum. Hopefully, the IBOC decoder software will be made available in the
future for free and in the public domain. That would make IBOC available
for decoding on any receiver using a computer. Imagine the possibilities
with a software defined radio such as the SDR-1000.
