News:

July 27^th 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.
