    Hi all
    Yes, DSP-23 is in trouble. In addition to not receiving radio signals from it on 
    the 6th Nov 2008 (see my SeeSat report around about that date) the satellite is 
    no longer keeping station but is slowly drifting eastward  with a rate due to 
    gravity alone. Radio signals were received from it on the 23rd November by Paul 
    Marsh and by myself on 24th November when I tried again but appeared weaker than 
    Optically it looks the same - Ive just finished observing for tonight and this 
    was one of the objects observed and I saw nothing unusual in its behaviour and 
    its still drifting.
    A study of the elements in CLASSFD.TLE will show problems showed up in 
    Quite ironic that DSP-F23 has apparently failed - DSP-24 and DSP-25 were 
    cancelled .
