Those who can remember monitoring Astra 2D will recall that signal strength increased in the autumn, reaching its peak in late November and December, when it was at its best for the year. In the fringe area where I was located, (Madrid) May to September was always weakest. Signals decreased from the end of January until equinox, stabilised, then weakened again. Overlaid on this was regular station keeping, every six weeks or so. All the indications from reception reports are that Astra 2F has followed the same pattern. Only in marginal areas does anyone notice. Chances are that 2E will be the same. Exactly why, who knows?
