I want to send a music with two signal but I am taking this error why ?

Hi,
I can see that it fails to set sample rate because it is too low. Try setting higher sample rate, at least 50 kHz.

Dont fixed anything How I can Send a signal with multi frequencies ?

Hey,

Looking at your GNURadio flowgraph I see multiple problems:

  1. Do not use “Throttle block” when using actual hardware throttling (board and software takes care of that)
  2. Do not use two sink blocks with one hardware board.

Also, If you are trying to send two distinct waveforms you should add them and not multiply.

If you are using Lime boards I highly encourage you to use gr-limesdr blocks because it avoids the problems which come up by using osmocom->uhd->soapysdr->limeapi stack. gr-limesdr blocks use limeapi directly.

Garmus I Have one Limesdr . How I can send one mesage in two frequencies one time 100 mhz after 120 mhz dynamic frequencies ? You know ? I want to dynamic frequencies when I am transmitting ?
