If you have a motor and you are able to automatically peak satellites,
the only thing missing is a program to find all the signals automatically,
including the ones which are turned on and off in a matter of minutes.

Just google for *blindscan* (and maybe my name) to find a
utility I wrote years ago and abandoned after failing to get
the corresponding mt312-autosymbolrate kernel patch integrated.

Next step, automatically upload found signals on some site, maybe
including a frame from the received video stream and let users
comment/moderate interesting ones on a sort of forum. :-)
Hmmmm, feeds...

Best regards.
