Just my
opinion but the issue with broadcast radio AM/FM is not the signal
method
its what they have for content. WHYY (NPR) has good content and
I
listen to them. Sirius for example has so much more choice (not
being part
of the clear channel effect). Also as Mark has pointed out
IBOC is not the
same quality as Sirius or XM.
Just my two
cents.

>> -Sid, The reason I mentioned XM Satellite radio in my Email to
you was because of a new antenna that is coming out. It may be out now, I'll
check Terk & a few others I know. But, in one of the Radio Broadcasters
Enewsletters I subscribe to they had an article about a new XM Sirius Antenna
that will bring XM/Sirius radio to most receivers that
already have RDS, or some kind of Data Sevice capabilities built in. Like the
new Eton E 1, it has no built in XM radio guts, it's all in the
antenna.
I have a trial antenna now and I am going to try it out on a few multi band
portables I own that have RDS but are analog & no XM. If you have ever seen
the Terk, or other model antennas for radios like the Eton E 1, all of the
receive circuits are in the antenna, not in the radio. One person properly
pointed out that XM/Sirius signals are in the 2,2 to 2.4 GHz Bands, which is
true. But, it is the antenna for radios like the E 1 that receives the signals
& processes them for reception on non satellite receivers. Many of these
receivers are referred to as "XM Ready". That means they have an antenna input
for whichever Satellite receiver they pick out.
