[QUOTE="dxsat, post: 437924, member: 193607"] Equinox troubles have not finished for this season, the sun is closest to the Astra 2A/B/C/D cluster on the 7th. and 8th. October in Cyprus. You will experience sun outage in the mornings on those dates. [url]http://www.satellite-calculations.com/SUNcalc/SUNcalc.htm[/url] At night there is a period of bad reception as 2D enters and exits the earth's punumbra, before and after the batteries are switched on during the eclipse. Period of maximum eclipse is on the same days as sun outage days. All this ceases when the sun appears to move to the south of the satellites' location, to start again in the spring. Off topic, but the above holds the key as to why reception is worse in the evenings on 2D, the satellite is receiving less sunlight during its pass behind the earth, as it is further from the sun, probably at a slightly different attitude as well. When the batteries are fired up during the eclipse, power is restored to early morning levels. Only those on the far fringes of the footprint see a difference, but it explains why those with a marginal signal lose weak 2D transponders at night. [/QUOTE]
