Microwave HamTV From Space (Not SSTV)

In addition to the amateur radio repeater and occasional Slow-Scan Television (SSTV), the International Space Station has also started transmitting HamTV. This is closer to "Fast Scan TV", or traditional digital television. It's also similar to what some earlier commercial TV satellites used (DVB-S). Unlike the SSTV signals, this one is up in the microwave S-band, around 2.395GHz or almost in the Wifi band).

So far there's not much on the HamTV signal, just a black screen. Eventually they'll start using this for more school contacts and other ham radio operations. You can find more information about it at the links below:
