Hi Alan --
I doubt you'll find many radios that support a 6-7MHz bandwidth around a
10.7MHz IF. That's way too great a percentage of the center frequency
for traditional radio design to work with. I suspect the 10.7 IF in the
AR5000 is not going to be able to handle more than NBFM, or at most WBFM
(eg, 200kHz or so) bandwidth without major surgery that would likely
render the radio useless for normal tasks. A radio that supports TV
bandwidths is likely to have a much higher IF, anywhere from 45 to 70MHz
or higher.

The ar5000 has a bandwidth of 10mhz

AOR claims there is a NTSC demodulator for the ar5000 it's called TV5000
Rumors says ar8600 has either 2 or 4 mhz bandwidth (i've seen both mentioned)
