Debug information question #8

Open janvgils opened 11 months ago

janvgils commented 11 months ago

Looking at the debug output my eye was drawn to the following message:

Jul 21 20:46:48 canberra satnogs-client[4826]: [DEBUG] setBandwidth: decimation < 4

I have been looking at CLI decimation options but could find a way to use this functionality. Based on the debug message, is it possible to alter the decimation value use by the AIRSPY?

Full debug output:
