After being declared dead 21 years ago in mid 1981 due to battery failure, AO-7 has miraculously sprung back to life and was first detected by Pat Gowen, G3IOR on June 21, 2002 at 1728 UTC. Jan King, W3GEY reports AO-7 is running off the solar panels only. It will only be on when in sunlight and off in eclipse. Therefore, AO-7 will reset each orbit and may not turn on each time.
On July 11, 2002 AO-7 was successfully commanded for the first time since it was declared dead 21 years ago. Commands were sent and accepted to change the CW beacon code speed.
Command investigation continues. So far, 11 different commands have been accepted by AO-7.
Yoshi Imaishi, JF6BCC is compiling an excellent list of observations. Please send him whatever you have. [email protected]

On November 21, 2002 Chris Jackson, G7UPN reported:
UO-22 is operating OK at the moment. Some new software has been loaded to try and keep the downlink operating most of the time. It seems that after around 60000 charge/discharge cycles the Nicad batteries are starting to show their age!
The downlink will be switched off from time to time over certain parts of the globe. This is required to allow the attitude control system to operate correctly since the power system cannot supply enough power to support both the transmitter and the magnetorquers.

The current configuration of IO-26 allows only limited telemetry in MBL (safe) mode. To enable full telemetry and digipeating, we must re-load the full IHT high level software suite.

SAFIR-M is a German amateur radio payload onboard the small German scientific satellite "RUBIN-2".
SAFIR-M was built by the German amateur radio association "AATiS e.V." (German acronym for "Arbeitskreis Amateurfunk und Telekommunikation in der Schule", which means: 'working group for amateur radio and telecommunications in schools').
SAFIR-M is designed as a "store and broadcast" system for APRS based messages, dedicated for the use of schools in combination with the existing WX-Net and planned buoy experiments in Germany.
Following listener reports and analysis, the TLE for NORAD #27605 (CELESTRAK: PAYLOAD A) is recommended.
The analysis of a recorded WAV file of a pass over Germany from 24.12.2002, 05:38 - 05:40 UTC shows unexpected effects:
a) The TX clock rate of the SAFIR-M 9k6 modem seems to have 9844 baud instead of expected 9600 baud. Reception of frames may be still possible with high RX field strength so that the DPLL of the ground equipment can lock within its tolerance range.
b) Additionally, it seems that the data line for bit 0 to the external memory of the PIC is stuck at "0", so that the parts of the transmitted MH frames could be damaged. CRC, NRZI, stuffing and scrambling are done correctly from the faulty data source.
For further examination, Martin DG8UAU has written a small software "SAFIR-M Decoder" (28 KB) to allow decoding of the received DATA0 frames. It is available at
http://amend.gmxhome.de in the section Aktuelles.Details on SAFIR-M can be found at
