The only restriction on subcarriers is injection levels, crosstalk to the main
carrier and other technical considerations.

It's not a subcarrier issue, it's a translator issue. Translators are not
allowed to originate independant programming; they must directly repeat
whatever the main broadcast transmitter is producing.

Does this local origination prohibition apply to subcarrier data as well,
or just to the main channel?

It used to be that the main carrier must be programmed when a subcarrier was
in operation, but I think the FCC eliminated that requirement about 10 years
or so ago. I don't think (but check with a good broadcast attorney) that
there's even decency regulations imposed on subcarrier operations, since it
won't be available to the general public.

Right. But the issue is the translator, not whether it's permitted to be
broadcast on subcarrier. The question is can you broadcast it on a translator
subcarrier without it being on the subcarrier of the main channel of license.
