RE: [Discuss-gnuradio] GnuRadio on PCI-104 (i.e., Fedora on USBFlash Drive)

William- Isn't there an issue of how much GNU radio can actually do on a Pentium M system? The Lippert board you mention looks like it's limited to 1 GHz or less with passive cooling. I assume this is a mil app, but you can use fan cooling? What will GNU radio actually be doing? -Jeff > Th

[Discuss-gnuradio] Specifying bandwidth for fft_sink

2008-05-01 Thread Steve Glass
Hi, Is there an easy way to set the bandwidth for the fft_sink display? I've filtered the original signal to the frequencies of interest but in an FFT sink the X axis is over 2MHz wide with my signals clustered into the centre. I'd like the X axis range to reflect the range of frequencies present
