Also, please\nlimit your uplink power, as it looks like this transponder is as sensitive\nas FUNcube-1. The spacecraft antenna is a monopole, so we would also be\ninterested in signal fading reports.\n\nThe comissioning of the transponder done to date is very limited, three\nactivations for 5, 10 and 8 minutes respectively. So your reports are\ngreatly appreciated.\n\nWe do understand this is a very short notice, but hope that some of you\nwill be able to participate.\nThis was a take-it-or-leave-it opportunity offered by the ISIS engineers\nfor our consideration, and we are again very grateful to ISIS and VKI to\ngive us this opportunity.\n\nWouter PA3WEG\nFUNcube team\n\nOn Sun, May 3, 2015 at 12:28 AM, Wouter Weggelaar <[email protected]>\nwrote:\n\n> Dear all,\n>\n> I would like to inform you all that tomorrow, Monday 4th of may, there is\n> a fairly high chance we will be allowed to test the AMSAT-NL transponder\n> for one full orbit.\n>\n> Details will be made available on short notice, but we are aiming for an\n> activation starting at ~08:30 UTC and lasting until ~10:10 UTC.\n>\n> The aim is to characterize the power budget on board EO-79.
