Re: [Discuss-gnuradio] Welcome to all the new folks

Hello,

An additional hardware option for GNUradio is the R2 receiver. There has 
been successful attempts to use the R2 with DSP (hardware based). The 
advantage of the R2 design are:

- High performance
- Low number of external components
- Coverage from LF to microwave
- Can make use of a standard computer sound card

One big disadvantage I see is the bandwidth when using the sound card 
interface (44.1 kHz sampling rate). But for those of us mainly interested 
in relatively narrow band signals, a standard sound card will be 
satisfactory.

An article describing some experiments with the R2 and DSP can be found at

SETI is also using the R2 for its hidrogen line monitoring. Details can be 
found at

Best regards,
