Dear Friends,
It is really a sad news. Bidding a farewell to AO-51 with a very heavy heart.
Looking at the success, we all at Upagrah Amateur Radio Club VU2URC at
ISRO Satellite Centre and AMSAT-India express our heartfelt and
sincere thanks, appreciations and compliments to the entire AO-51
(ECHO) team.
The AO-51 mission is accomplished with a great and complete success.
AO-51 was truly one of the best amateur radio satellites. It was a
very favorite for many of our VU hams for its strong signals and ease
of operations. we really enjoyed on being AO 51 very long time and it
is really hard to bid a farewell to this wonderful bird.
'Thank you AO-51 for your great and fruitful services to the World of
Amateur Radio'.
Our congratulations to the entire control & command team for their
extra-ordinary efforts and incredible technical competence exhibited
in keeping up this 'Cute Little Boy' healthy & alive in orbit for such
a long period of time.
We take this opportunity to thank each & every one associated with
this great project and wish AMSAT-NA all the success in their future
endeavors. We at Upagrah Amateur Radio Club VU2URC at ISRO Satellite
Centre and AMSAT-India assure all the possible and best help for the
common cause of Amateur Radio.
73 es good wishes for a 'Happy Christmas & New Year'.

Quoting Andrew Glasbrenner <glasbren...@mindspring.com>:
It is with a heavy heart I report that AO-51 has ceased transmission
and is not responding to commands. The last telemetry data indicated
that the third of six batteries was approaching failure to short,
and observations indicate the voltage from three cells is
insufficient to power the UHF transmitters. The IHU may continue to
be operative. Initial tests with the S band transmitter were also
not positive, although more attempts are in order. We have tried
leaving the satellite in an expected state where if voltages climb
high enough, the 435.150 transmitter may possibly be heard.
The command team will regularly attempt communications with the
satellite over the coming months (and years). There is always the
possibility that a cell will open and we could once again talk to
our friend while illuminated. Thanks to all who helped fund, design,
build, launch, command, and operate AO-51. It's 7 year mission has
been extraordinary. Please support AMSAT's Fox-1 project, and other
AMSAT projects worldwide with your time and money.
For the AO-51 Command Team,
73, Drew KO4MA
