We (@cgbsat and I) have some issues with the Dwingeloo telesope’s gain settings. We have two feeds (horizontal and vertical polarization).
Example observations are SatNOGS Network - Observation 4792471 (bad, taken with B210 on H-feed) and SatNOGS Network - Observation 4792479 (good, taken by @cgbsat) with other dongle on V-feed).
We have pretty excluded that the difference is based on the polarization. We’ve explored some different gain settings, but I notice that the gnuradio Soapy block actually sets a lot of gains, where only ‘overall gain’ is set by the SatNogs parameter gain
. Could it be that one of the other gain settings (which seem to be hardcoded) is non-optimal?
