Re: LimeSDR | Sinewave test | Glitchy behavior

Opps - ignore the following -I just realized  in my mind I was going the wrong direction - I got twisted:   "If you were to add a signal source of 48 kHz, you would need to add a rational sampler in front of the WBFM block for a quadrature rate of 480 kHz" If you add a 48 kHz signal inste

 Hi Anish - I would argue the flowgraph is a potentially a  model for a broken audio device :). That is, the input signal to the WBFM block is not a 48 kHz signal - it's a null source, but you're telling the WBFM block to expect an input frequency of 48 kHz. If you were to add a signal sourc

Hi. I performed some more tests and report the results on this thread. https://discourse.myriadrf.org/t/glitchy-behavior-gr-limesdr-limesdr-usb-sinewave-test/7022/10?u=vu2tve I'd love some advice with which I can produce a simple FM modulated sinewave with gnuradio and limesdr. If someone on this

Look at your RTLSDR sample rate limitation For example the RTL2832U can sample from two ranges ... 225001 to 30 and 91 to 320. On 13/05/2021 22:30, Rob Roschewsk wrote: Hi all!
