I'm looking for an FM capture card that is DVR-like (DAR? Digital Audio
Recorder). Something that I can set the frequency and a start and stop
time. There are some smaller, local radio stations that I would like to
record that are NOT going to have an internet-feed version any time soon.

I have tried to find info on something like this but most FM recorders
are part of a TV/FM card. ...and since most ubuntu (and linux, in
general) users care only about the status of the TV portion, it has been
nearly impossible to find the status of any FM recording ability.

So, are there any sites that have a list of "working in Ubuntu" FM
recorders?
Are there any "stand alone" or USB FM-only gadgets?
Can anyone supply some Google-search terms that would help me find the
FM recorders and NOT FIND the millions of useless hits that are about
the TV portion of a combo card?
