v1 v2 98 98 === Troubleshooting === 99 99 * If the receiving script is not showing any activity, it most likely the script parameters need to be tweaked. USRP radios (any radio in general) are not made the same due to variations in HW component quality and tolerances. Each radio has it's own sweet spot for best transmission and reception. For different USRPs on the grid (or other sandboxes) raising or lowering gains, amplitude, and/or other parameters is required to establish a solid radio link. 100 As an example if the gains are set too hi, signal can become saturated, clipped and distort at the analog-digital interface. If the gains are set too low, the signal will just blend in to the noise floor especially for simple modulation schemes. For a description of other parameters, use the --help command get a listing. 100 101 As an example if the gains are set too hi, signal can become saturated, clipped and distort at the analog-digital interface.
