ARISS has scheduled its next International Space Station slow-scan television activity for October 2–6, giving Arkansas Valley operators a defined window to receive the Student Education image series. Expedition 75 Series 33 is listed to begin Friday, October 2 at 09:00 UTC and conclude Tuesday, October 6 at 15:55 UTC, subject to station operations.\n\nThe downlink will use 437.550 MHz FM and Robot 36 SSTV. ARISS specifies a 36-second image transmission followed by a two-minute pause. The station’s Doppler movement matters on 70 centimeters: ARISS advises listeners to account for the frequency shift during each pass rather than leaving a receiver fixed at the nominal frequency.\n\nThis is a receive-only opportunity, so a station does not need to transmit to take part. An FM receiver or transceiver that covers 70 cm, a suitable antenna and pass predictions, plus SSTV decoding software are the practical starting points. Clear satellite passes will be short, so having the receiver and decoder ready before acquisition of signal is important.\n\nARISS says received images can be submitted to its SSTV gallery, where participants may qualify for an electronic event certificate. Operations can be paused around scheduled school contacts, and the organization notes that the timetable can change. Colorado operators should check the official event page before each planned pass for current details. Source: ARISS.
