[BC] Real cases of IBOC interference wanted for research purposes

[Stan Tacker]

Anyone have experience with 2nd adjacent stations running IBUZ in the same
market?  In this market we have 1530, 1550 and 1570.  The 5 mV contours of
the 1530 and 1550 are close to each other.  The 1570 is moving in to but up
against the 1550.

The BUZZ I observe in this market extends 22.5 kHz above and below the
carrier frequency.  

Sounds like a train wreck in the making.

The IBUZ cheerleaders assure me that digital requires only a fraction 
of the power of analog. 250 watts should be monster power for 
digital. That doesn't seem to apply to Western MA but I'll accept the
concept.

If IBUZ doesn't respect the physics of analog directional arrays and 
a 50KW directional throws 3KW outside their pattern it would seem to 
me even a BA Receptor should be able to receive it with an Art Bell 
style antenna setup if you live a few miles from the transmitter 
site. If you have a Yamaha AV receiver you'll receive it in crystal 
clear, almost, kinda, a little bit, sort of CD quality miles and 
miles away. It's an awesome receiver even with the BA rat tail antenna.

Please understand that the copywriter who claims CD quality has a 
congenital hearing problem. He's deaf.
