July 18, 2023— Amateur Radio on the International Space Station (ARISS) in collaboration with the American Radio Relay League (ARRL), plan to carry out a special Slow Scan TV (SSTV) experiment from the ISS on Wednesday, July 26, 2023. During the event, the Columbus Module Repeater, transmitting at 437.800 MHz, will carry a message to be received by teachers attending the ARRL Teacher’s Institute class. The pass will be over the Mid-Atlantic / New England area with transmissions scheduled to begin at 20:05 UTC (16:05 ET) and ending at 20:20 UTC (16:20 ET). If necessary, a backup window will be 21:40 UTC (17:40 ET) to 21:55 UTC (17:55 ET).
Radio enthusiasts are welcome to download the message and follow along with the event, but we ask that all hams please refrain from using the repeater for voice contacts during the event.
Please understand this is a special experiment conducted through ARISS and the ARRL. All regular operation of the repeater should continue to take place in voice mode only.
