On the occasions when it happened here\nover the UK, the bird \"should\" have been in high power mode, but after\nlooking at telemetry it appears that it had switched into low power mode\nmuch earlier that than usual, from memory the footprint was only half in\neclipse. Also noticed that before it cuts off that there is usually 10-15 or\nso seconds of a silent carrier. On another occasion it cut out halfway\nthrough a SSTV transmission - this I'm almost certain shouldn't have\nhappened due to the way the firmware was written.\n\nPerhaps a bad solar panel contributing to low voltage when approaching\neclipse? I had noticed one of the panel temps was over 75c on several\npasses.\n\nIt certainly looks like there is some intermittent problems beginning to\nraise their head, lets hope it's not a steady decline in the bird's\nperformance as gathering the SSTV pics, telemetry etc has been a very\nenjoyable change to the usual FM/SSB activity.\n\n73 de Pete\n\nMi0VAX\n\n\nOn Sat, Aug 27, 2011 at 3:59 AM, Carl Rimmer <[email protected]> wrote:\n> I was having a really good pass gpong from my NW-SE and I had copied 6\n> frames of Telemetry and 5 frames of KURSK data when the bird just went\n> silent.
