Nytt schema from. januari.
ALON/ALAT is approximately 337 / 3. The U, L1 -> S2 passbands are now active from MA 20 to MA 140. Please run low power and stay well clear of the beacon. Thanks.

The lowering of ALAT is progressing well. We are currently holding ALON at 335-340 and lowering ALAT the last 10 degs toward 0.
We will allow a few more (2-3) orbits for this to occur, to verify our position, and for the solar angle to decrease to below 40 degs. for extra power. After that we will activate the passbands from MA 20 to 140.
As we chase the sun back to 0/0 at about 1 deg/day, the passbands will be lengthened and moved more into the second half of the orbit.
All the best for 2004 from the AO-40 Command Team.

Jag har idag lyssnat p satelliten och avkodat telemetrin,
Alon/Alat 343/22 1622 svensk tid.
Beacon r mkt stark, min mottagningsutrustning bestr av en 60cm parabol frsedd med patch och en konverter p 1Db Nf.
Avstnd till satelliten 53254km riktning 95AZ 5EL.
S-mtaren visar ca 5 S enheter och Db mtaren 16DB, squinten r fr nrvarande 16 grader.
Satelliten frvntas att ppna fr trafik inom en vecka.

AO-40 is now at approximately ALON/ALAT = 45/24.
As we have reached our desired ALON/ALAT and the sun is in prime position for the move, we have stopped magnetorquing and will begin drifting immediately. The passbands have been turned off and will remain off for approximately 4 weeks. The middle beacon will remain on.
Drift rate is approximately 16 deg/week. We should be in a position to begin lowering ALAT and restarting the passbands during the 4th week in December.
The command team will make every effort to have FEC telemetry active, but this may not be possible on every orbit.
Thank you for your patience.
