July 27th 2025: HamTV installation has been scheduled for 1405 UTC on Tuesday 29 July 2025.
A succesful 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.

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/ARISS_SSTV/ . 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/
