First Post!! - Has anyone properly (i.e. in terms of dBs) plotted the variation in signal level of the Astra 2D signal in Spain? I’m sure many are familiar with Stefano Ferrairo’s excellent work on the variation in 2A/2B North transponders http://idd009rc.eresmas.net/, has anyone plotted similar variations for 2D? Also, and this may have come up elsewhere in this forum, do we have an accepted scientific explanation for the phenomenon?
