Re: [IRCA] SE FL IBOC Status

["David Gleason" <david@xxxxxxxxxxxxxxxx>]

Again, it is about usable signal, not signal coverage. In the size markets
where we will first see HD, the usable analog signal has to be very strong
to be usable, generally over 10 mv/m. extensive analysis of Arbitron diaries
shows and proves this. The HD signal seems to be usable beyond the 10 mv/m
contour, as it is less subject to interference and the noise that ruins all
but the strongest AM signals.

Dave:

Take a look at the iBiquity test data in
http://www.nrscstandards.org/DRB/NRSC%20eval%20iBiquityAM/amibocevaluationre
port04062002.pdf .

You'll see on page 43 a map that contradicts what you say below. On p. 45
they are very clear that at night, digital coverage is reduced relative to
the analog coverage.

The HD goes beyond such contours with a listenable
signal per tests made on several stations.

And inconsistent with iBiquity's own test reports, where the IBOC contour 
was graphed  in detail. The IBOC contour never came close to the analog 
contour.

To see their results, go to the NRSC pages on the NAB site.
