via the ARRL: ARISS Plans Do-Over of Slow-Scan TV Transmissions over February 15 – 17 Weekend

Amateur Radio on the International Space Station (ARISS) is planning another popular slow-scan television (SSTV) event in the wake of an SSTV experiment last weekend, during which signals were reported to have been weak. Even so, more than 5,500 images were submitted. Transmissions are scheduled to begin on Friday, February 15, at 0845 UTC and run through Sunday, February 17, at 1725 UTC.

“The ARISS team wanted to give the community another opportunity to download the SSTV images we developed for you, given the weak-signal situation that occurred last weekend,” said ARISS-International President Frank Bauer, KA3HDO. He clarified that the same 12 images transmitted last weekend will be used for this weekend’s experiment.

Bauer said it’s not entirely clear what caused the low-signal issue last weekend. “We believe it may have been either a loose feed-line cable or an antenna switch that did not fully engage,” he said. “Once the crew reset the system and checked the cabling and switches, the radio system started to perform nominally.”
