It turns out that powering the Norsat 3220 LNB for C-band from a satellite receiver can be problematic. Details can be found in the second appendix at the end of the article about the reduction for the attachment of Corotor Chaparral.

I repeated the signal strength measurement from the position of 28.2°E during 24 hours. I measured the new transponder in a DVB-S2 system with BBC Red Button 1 HD. I performed the measurements 7 days in a row so that it was possible to assess the effect of the current weather on the receptivity of the said transponder. You can find the measurement results in seven charts here.

Added an article about the measurement of the course of the signal strength of the Astra 2E satellite at the position of 28.2°E in a time range of 24 hours. I measured the signal strength of the Freesport HD program in minute intervals. You can find the resulting graph here.
15/2/2021
I prepared an overview of the signal strength of individual transponders at the position 28.2° E. I conducted the survey today from 15:00 to 15:35 Central European Time. You can find the results here.
