Nah, a bit esoteric / out of scope, let alone unwieldy, physical 
equipment wise.

Now, if someone has a USB ATSC tuner, and an internal directional 
antenna, for watching under Linux, that's a topic. (Though not for me - 
not my setup.)

It has occurred to me how such a setup (With a wrapped up wire FM 
dipole?) could be useful when travelling. However, if one is in a hotel 
with free local TV there doesn't seem much point. If camping, with 
electricity, tvfool.com would be useful for which direction to look to, 
and for what channels, will be useful.

Apparently cc under digital is different. In at least some cases, rather 
than being a text substream, its an image overlay - so given the not 
dead perfect signal I'm getting, perhaps that explains it.

<sigh> No, never occurred to me. Pardon me while I go look ... (-:

(Thanks.)
