Second SSTV image sent via transponder

W8ZCF and KB8VCO were successful in transmitting a picture and receiving back an image via the ARISSat-1 transponder. This image of a license plate was received on November 12, 2011 at 1908 UTC.
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. [info from AMSAT-BB]
