texting alone is not a salable benefit. I can't think of a way to make
it
so. It is, however, an added benefit, especially to HD digital audio.



Seems like the benefits of texting would be the same regardless of the
method of audio modulation.

Text is more easily implemented, without potential artifact, with
more possible versatility in digital modulation, than as an analog
adjunct.

OK, I see the point. RDS has the same problems as SCA as far as FM goes.
But, as I understand, there's some unused overhead in RDS such as font
selection and such which could be better used in an text service.

And the problem with digital modulation can't be all that different. The
bits used for text are bits which can't be used for audio.
