Easy --
Use either the Sony AVC or the Mainconcept AVC encoder, render as .mp4, then rename the extension to .mov (renaming is optional).
Works like a charm.
There is no gold standard for broadcasters -- they all want it a little different.
Contact the station and see how they want it, I would keep the AVC bitrate high, probably around 5,000,000 bps if the source is MPEG-2, 15,000,000 bps if the source is DV25.
