gnuradio, sdr, DAB USB dongles, and so forth?

[Carruth, Rusty]

Actually, the software on your pc turns off the decoder in the dongle
and takes I and Q directly, then decodes it on the PC.

 

Probably won't work for TV reception here (besides, the bandwidth you
get that way is 'only' about 2MHz wide), but NBFM, WBFM, AM, PSK, FSK,
blah blah blah can all be decoded if they run in under 2MHz bandwidth.

Sounds interesting, but if it won't work with U.S. digital tv, how would
you test it?  Wouldn't it only be useful overseas?

	Specifically I am thinking of using one of those USB TV
receivers (from overseas - they work with DAB or DVB+T which isn't our
standard over here in the states) and either gnuradio or something else.

	 

	There was an article in QST (a ham radio magazine) 'recently'
about it, so I rushed out and bought one of the USB thingys and now I'm
trying to get all the pieces in the right place.  I've tried SDR#,
gnuradio-companion, and probably a few other things.  The controls for
SDR# don't seem to work for me, and also I don't seem to be able to get
the receiver and the software tied together.

	 

	Is anyone else playing with this?
