No, it is not.

It is true that there are two separate carriers, one for sound and one
for video. And it is true that the sound carrier is FM modulated and
that the picture carrier is AM (actually VSB) modulated. The sound
carrier is offset from the video carrier by -4.5MHz, but it is in the
same band.

it's +4.5 MHz... at RF ...

to the OP, you can get a DTV converter and a small FM transmitter
(like the kids use for Ipods but a little more powerfull, they are
avaialbe) , connect the audio from the DTV converter to the small FM
transmitter and then you use your FM radio to listen to the TV.
