As for the standards, you'd want to be sure to get one intended for NTSC, so the sound subcarrier is on 4.5MHz, and not 5.5 or 6.5 for some PAL countries.

Yes, I came across a section on antiqueradios.org about rf modulating where I read it could just be done with an RCA->F adapter.
I think I have an old VCR somewhere I can adapt for now and then just browse "that place" for a good deal on a BT. The ones I found earlier were mid-band so of no use to those of us that deal in tvs with channels that don't go that high.
