  This morning, during 20:50z〜21:20z, I tried to hear 145.890-910,
435.400-500, 2400.200-600 and 2401.200-600 but could not get any
signals from Sat. AO-40 should be at around 10,000km distance and
MA was 4-10. I used 6ele(144), 6ele(435) and 20 turn Helix / Drake
for receiving. So If there was something the sat transmitting, it
might be received...

  I hope that it is not so serious thing.

  OK, I will wait for this. At afternoon on Dec-16 - it will be at
night time at here Japan, we Japanese hams will not have window and
our AO-40 will fly over NA/SA. I hope for a good news from you who
will watch it.
