Hi Farrell,

great post and congratulations.
I am currently having fun with the 1000BPSK telemetry.
Next experinment will be a QSO through the transponder.
Its good to have a satellite that presents a few challenges.

I echo your thanks to the entire ARISSat team.

TRANSPONDER

  



On November 12, 2011 at 1908 Z my son Jeff, KB8VCO and I were successful in 
transmitting a picture and receiving back an image via the ARISSat-1/RADIOSKAF-V 
transponder.




Separate MMSSTV software setups on 2 computers with mode Robot 36 were used to 
Tx 435.750 LSB up and Rx 145.930 MHz down. It was a challenge, over several days 
of trying , to find the satellite in a favorable position with its 
(inadvertently) shortened antenna. Doppler along with Tx and Rx antennas were 
manually controlled.




A picture of the original (my auto license plate) and the received picture from 
the satellite has been submitted to the ARISS SSTV Gallery. 





It is hoped others will try a similar experiment via the transponder and perhaps 
pictures could be exchanged. It is noted that Henk, PA3GUO also sent and 
received an SSTV picture as may be seen in the Gallery. 





Respectively submitted, with much thanks to Lou McFadin, W5DID, ARISS Hardware 
Engineering Manager and his team along with Sergej Samburov, RV3DR, Chief of 
Cosmonaut Amateur Radio Department for his engineering and testing contributions 
in Korolev, Russia. A very exciting and challenging satellite for Amateur Radio 
has been provided. Launch was August 5, 2011 but Re-entry according to recent 
reports may occur within the next few months.
