Can anyone tell me if the MET reading is zero after a reset or should it read 15? For Arissat-1 that is. Terry VK5GU

MEDIA ADVISORY: M11-169 MISSISSIPPI AND LOUISIANA STUDENTS TO CALL SPACE STATION ASTRONAUTS WASHINGTON -- Students gathered at NASA's John C. Stennis Space Center in Mississippi will place a long distance call to astronauts aboard the International Space Station at 1:35 p.m. EDT on Thursday, Aug. 18. Mississippi and Louisiana students in kindergarten through twelfth grade will ask Expedition 28 Flight Engineers Ron Garan, Mike Fossum and Satoshi Furukawa questions related to mass and weight. The experience is designed to enhance the students' understanding of scientific principles, physics and space. Stennis' education office is hosting the call, which will include a video link with the three astronauts and will be broadcast live on NASA Television. To attend, journalists must contact Rebecca Strecker at 228-688-3249 no later than 3 p.m. on Wednesday, Aug. 17, to arrange for clearance and escort to the event. This in-flight education downlink is one in a series with educational organizations in the United States and abroad to improve teaching and learning in science, technology, engineering and mathematics studies. It is an integral component of NASA's Teaching From Space education program, which promotes learning opportunities and builds partnerships with the education community using the unique environment of space and NASA's human spaceflight program. The exact time of the downlink could change.

ARISSAT-1 report
by g.shirville＠btinternet.com 15 Aug '11

15 Aug '11

Hi All, Just popped outside from the IARU Region 1 Conference meeting to catch an ARISSAT pass. Good signals with an Arrow and a FCD and also using a G0MRF prototype filter amplifier with 5v being supplied by the Dongle. (Thanks David for the loan) Voice telemetry reported MET of 41 mins - which corresponds very well to when it left eclipse over the Pacific. Battery volts 35.74 and current -4ma The signal had no fading but several occasional ~ 100 msec breaks in transmission were noted. best 73 from sunny ZS6 land Graham G3VZV
