Varios ham radio satellites news.
Frn ANS:
A two ham Expedition 7 crew arrived at the International Space Station on April 28th to replace the crew currently on board.
Two men… cosmonaut Yuri Malenchenko, RK3DUP and astronaut Ed Lu, KC5WKJ, have arrived…. the first team ever to get to the I S S aboard a Russian spacecraft. They replace 3 men… Commander Ken Bowersox, KD5JBP, Don
Pettit, KD5MDT, and Nikolai Budarin, RV3FB. That team flew back to earth on the third of May.

Status från 11 maj
From Stacey: We are about to begin active magnetorquing to hold ALON relatively steady and begin to lower ALAT. Current ALON/ALAT is approximately 330/25, but better determination will be possible once the ALAT drops below about 15 degs. and the earth enters the camera field of view.
We hope to have the passbands on during the first half of the orbit within about 1 week, if all goes well.
The A-blk message of the day section now includes height, Lon/Lat of the subsatellite point, and ALON/ALAT. All of these values are generated by the IHU-1 software based on its orbital and magnetorquing calculations. ALON/ALAT is also updated from the ground when a new magnetorquing command is issued.

AO-40
There has been a high level of mail in recent days re: hearing AO-40.Readers of the amsat-bb should be aware from Stacey W4SM s recent posts that AO-40 has now entered a drifting phase.
The information below (prepared by W4SM) details the predicted behaviour of AO-40 through to the middle of May.
Please note the information is on a day by day basis, not orbit by orbit.
The information is presented to assist those who are fine tuning their gear,collecting telemetry etc.
On the subject of telemetry collection the norm for 100% OK blocks is for Squint angles, 0 to 36 and 60 to 70 degrees.
I mention norm, because the above ranges of squint angles apply when the Alon/Alat are nominally 0/0.
However during the drifting phase the norm no longer applies, specially in respect to the side lobe at squint 60 to 70 degree. Good reception of telemetry is available in the 50 to 70 degree range, but is range dependent.
There are lots of positives that can be gained during this drifting phase.Every block of telemetry forwarded to ao40-archive@amsat.org is greatlyappreciated.
