When: 2026-08-22, 19:00 CEST Where: Svartbäcksgatan 65, 753 33 Uppsala Stream: https://bbb.cryptoparty.se/b/upd-0mo-m2u-aq8 Slow-scan Television Slow-scan Television (SSTV) is a method to transfer pictures using audio frequencies, usually on top of radio waves. It is popular as an amateur radio application but has historically even been used during space missions. I will present the history of SSTV, how it works and how it is used in amateur radio. I will also try to compare it to analog TV and fax. Finally, there will be a live demo. Herbert Lange (University of Gothenburg) The lecture is free and open to everyone.

Update har fått ett erbjudande om en mikrofiche-läsare. Problemet är att den måste hämtas i Stockholm på Sveavägen 24–26 **imorgon kväll/natt**. Finns det någon som kan hämta den och förvara den åt oss tills vi kan köra till Stockholm? Om du kan hjälpa till, hör gärna av dig! Hälsningar, Anke/zeltophil
