I am using GNU RADIO on WINDOWS 10 to do amateur radio DVB-S2 emission experiments with the limeSDR mini
I am not a programmer.
I installed PothosSDR 2021 07 25 vc16-x64 with the Lime suite
I am using the Soapy Custom or Soapy lime Sink or Osmocom Sink module.
We are doing very low bit rate testing in DVBS2 emission.
With SOAPY modules the sample rate is limited to 100,000cps
With the Osmcom sink module I can go down to 40000cps with the device argument “driver = lime, soapy = 0” but the constellation and the results for all flow rates are much worse (m e r)
While it is the same driver
Is it a problem with the limitation of the driver or the GNU Radio module ?
Is there a way to “force” the sampling frequency lower for the SOAPY sink module ?
Thanks for your help.
