The PBS tech conference was host to a laptop w/BBTI datacasting demo from
channel 11 on black mountain. A BBTI (used to be B2C2) brick was used, and
the demo was set up in the MGM at a film-protected window pointing south,
but with a diagonal view of black mountain. SpectraRep gave a demo using a
small dual element antenna that must have come from a Motel 6 in the 1960's.
No reception with those bunny ears pointing upwards, so I just laid them
horizontal, elevated the antenna to a chair (away from the ground!), and
pointed them right at black mountain. Chaching, 80% signal strength.
Unfortunately, packets were lost left right and center due to multipath, but
the KenCast ECC repaired all the files (see, a use for datacasting after
all). The other datacasting vendor's system was not so lucky -- to the point
of not even seeing any pipe, let alone data. What can I say, Kenny kicks
butt.
I won't mention the other boards in this thread - we had extremely bad luck
with them at NAB2001, 2, and 3, and they served as demo pieces for the most
part.
Cheers

For my two cents worth - when accessDTV demo'd from Treasure Island, NAB
2000, the Hilton Suites NAB and CES 2001 and Embassy Suites from 2002 CES,
we were able to tune with a Silver Sensor or RS double bowtie (even when we
put the antenna in the personal effects safe at the Hilton in 2001 -in other
words, the cable was the antenna as well). We also tuned from the show
floor at CES 2001 much to the dismay of the anti-ATSC team deployed at the
time by Sinclair.

I'm not surprised they didn't call you back. The glass seems to be
impregnated with a metal film. We (previous company) were not able to get
our demo to work (2001 NAB) looking out the window using three different
antennas from the 18th (IIRC) floor. We had direct line of sight to Black
Mountain (higher peak) which is just east of due south of the Hilton. We
were able to get it to work fine at both the Hard Rock and the Amerisuites
as well as an office building across the street from the Hilton all through
the window glass.

Did anyone get to see an actual demo of USDTV at NAB.
They had suites at the Hilton and Bellagio. I went to the Hilton
suite where they had a receiver and a small outdoor antenna on a
tripod pointing out a window. But it was not operating; they told me
they would set up a demo for me the next day, but never called me
back.
One interesting note: the room on the hospitality list in the lobby
was not being used. That room had windows facing NE, which I believe
is a direct view to the Black Mountain antenna farm. They set up in
an adjacent room that had a view to the SE. I don't think this room
had a direct view to the Black Mountain antenna farm.
As a point of reference, it looks like there are two antenna farms in
the McCullough mountain range. The main farm is lower, just above the
pass that you drive through to get to Boulder City. There area few
towers to the south at a higher elevation. Which area is the Black
Mountain antenna farm?

Craig
