The audio carriers for the remaining VHF channels were outside the broadcast
FM radio band and the UHF (14+) were way outside the broadcast FM
radio band. Adding circuitry to handle the wide VHF range required
along with the UHF to a standard Broadcast FM Radio-band receiver
in order to recieve audio from the NTSC channels other than six would
have to be recouped via higher cost to the buyer of the set.

A friend used to have one of those TV-band radios. It had 2 additional
bands, one for TV-Lo (2-6) and the other for TV-Hi (7-13). No UHF, maybe
it was too expensive to add circuitry for such hig frequencies.
