I wouldn't consider 6.0V and 9.6V for a comparator as "relatively equal". I'd say they were considerably different.

It looks like there is a comparator on the MC3302P IC that is outputting high even though its two inputs are relatively equal (U301D, inputs of 9.6V and 6.0V should generate a low output...instead, it's high and appears to be keying the transmitter via U302).
