Reg : GNU RADIO HARDWARE QUERY

GNU Radio

Dear All,

   I have built the GNU radio system and I'm working around with the

examples. I am having a idea of implementing a system where one radio
station will be streamed to the soundcard while the other stations are
being recorded in the background. From what I understand from Dawei
Shen’s tutorial, the USRP in it’s current configuration will perform the
downconversion and provide me with the baseband signal of a single FM
station only, to which the USRP is tuned. Is there any possibility to
receive more than one station using the USRP simultaneously??

 If not, are there any low cost alternative to receive more than one

station at a time?? I’m thinking of using a High speed ADC (Like AD9874
evaluation board) but i’m not clear about the RF Frontend. What sort of
receiver do I need if I am to receive more than one station??

Thanks

The USRP can receive many stations at once. There is a 2 station
example in the usrp examples directory.
