It is weak, and it seems that\nit tries to modulate, but it doesn't modulate well and it shuts down,\nand continues doing this on and on as long as someone tries to active\nit. I would say that it responded to my PTT (using 5W to 3el) well, but\nI can't be sure, as there were a handful other stations trying.\n\nFinally, the statement that CAS-2T will not be separated from the final\nstage rocket and will re-enter in 10 to 30 days doesn't make any sense\nat all. First, in the image of CAS-2T shown on AMSAT-UK, it just looks\nlike a regular cubesat, so no way that antennas and solar panels would\nwork fine without separation from the rocket.\n\nSecond, the TLEs for this launch are already in Celestrak and\nSpace-Track. There are 6 objects tracked (A through F). Mike DK3WN says\nthat object E is a good match for the Doppler profile of CAS-2T CW\nbeacon. My observations on the 17:30 pass agree with him. Objects A\nthrough D are on 512km x 492km orbits. Objects E and F are on 1030km x\n504km orbits. There is no way that any of these objects (especially E\nand F) will decay in less than a month.\n\nFor comparison, according to Space-Track, NORAD ID 41559, which is a\nCZ-4B rocket body that was launched 30th May, sending its payload into a\n500km circular orbit, and is currently on a 360km x 240km orbit, will\ndecay around 15th December. This is 6 months to decay for the rocket\nbody of a similar launch.\n\nHopefully Alan BA1DU will be able to give us more accurate information\nabout this launch.\n\n73,\n\nDani EA4GPZ.\n",
