Hi Antmrt, The FFT plots (there are several available in GR) don't have a bandwidth of their own, they just display the FFT magnitude of the input sample. Frequencies are only for display and are usually calculated by the sampling rate parameter you set. That has no effect on the plot itself, but only on the axes' labels. If you want more bandwidth in your plot, you have got to have a higher sampling rate. If this relationship is new to you, I may recommend the recommended reading page on the GNU radio wiki, which, ironically, is not reachable for everyone right now, but that should be sorted out in a few hours (I hope). So: The Bandwidth you see is the bandwidth you put in; there's no way around that. If you're having something that smaples a complex signal at 100kHz sampling rate, you cannot expect your FFT to show higher frequencies than that.
Greetings, Marcus > How can we increase the bandwidth of the FFT plot. The bandwidth is only > 0.1MHz, how can I increase that to at least 10MHz.
