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.
