Wed 2026-03-25 TEST ISS Ham Video Color Bars/Tone successful

A successful install should have the HamTV equipment active around 1605 UTC and transmitting a carrier on 2395 MHz. Estimated power at the antenna is approx. 2 watts, RHCP.
HamTV is the name of the Digital Amateur Television (DATV) transmitter of the International Space Station (ISS).
The HamTV equipment is installed in the ESA Columbus module from the ISS.
HamTV was developed primarily for educational live ARISS contacts with astronauts.
More info on HamTV and reception at BATC wiki: https://​wiki​.batc​.org​.uk/​H​A​M​T​V​_​f​r​o​m​_​t​h​e​_​ISS For the latest news of HamTV on the ISS and reception reports: https://​forum​.batc​.org​.uk/​v​i​e​w​f​o​r​u​m​.​p​h​p​?​f​=​117 You can also follow status reporting on the AMSAT Live OSCAR Satellite Status Page:https://​www​.amsat​.org/​s​t​a​t​us/

May 14^th-20^th 2025: SSTV event from ISS

April 1^st 2025: Fram2, the first human spaceflight over the Earth’s polar regions, announces that SpaceX is targeting Tuesday, April 1^st 2025 for Falcon 9 to launch the all-international crew of four aboard a Dragon spacecraft to a 90-degree circularized orbit from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. Fram2 will have up to three launch attempts within a three-hour launch window, with SpaceX targeting 03:20 UTC for liftoff.
Rabea Rogge LB9JN/KD3AID will transmit SSTV images on 437.550 MHz.

February 13 – 17 2025: ISS transmits SSTV images in PD120 format on 437.550 MHz.
This is a test for the FRAM2HAM participants, but any HAM or SWL can receive those pictures and is encouraged to upload the files to the ARISS gallery at https://​ariss​-usa​.org/​A​R​I​S​S​_​S​S​TV/ . Awards will be available.

January 2025: FRAM2 space mission will be the first human mission flying a polar orbit.
Rabea Rogge LB9JN/KD3AID will be on board with an amateur radio station to promote STEM with the FRAM2 HAM competition. More on https://​fram2ham​.com/
