2005-03-18 Thread Dan Gisselquist
Hello all, I'm looking for someone who could get me a 30 second cut of the 14 MHz band from 14.0 MHz to 14.1 Mhz. I'm hoping for roughly 30 seconds or so. I figure 8 bit samples, at 250 ksps, for 30 secs -> about 7.5 Mbytes. What I'd like is a cut, very similar to the one RFSpace shows at, h

Dave, A standard header for data files makes a lot of sense. I have struggled in times past with creating file formats whose useful lives haven't been as long as I've desired. Ideally, you want a format that grows as your needs grow, without requiring you to rebuild all of your legacy softwa

Dave, You might consider placing RFSpace's SDR-14 on your list of hardware. You can find information about it at http://www.rfspace.com/sdr14.html. Dan On 03/08/2005 10:31:49 PM, David Carr wrote: Hi all, I've compiled a page with a list of GnuRadio resources that I've encountered. I'm sure

Dave, I've worked this problem a couple of times before. The fastest answer is not to plot every point. If you instead cluster points of the same color together, and then plot bars instead of points, the graphics algorithm will go much faster. A piece of some code that does this looks sort
