400Mhz QFH

Submitted by smeuse on Thu, 17/07/2008 - 19:13.

I've recently come into possetion of a 400Mhz QFH antenna. Are there any sats down there? What might this antenna have been produced for?

SSCS on 400 Mhz.

Hi, the Space to Space Communication System (SSCS) is working a bit higher around 410-420 Mhz.
It´s active during docking of a Space Shuttle to the ISS and during EVA´s with the American EMU Space Suits.
I guess it´s using low power as it is mostly used for short range communications.
The voice, video and telemetry is transmitted in a digital (I guess QPSK modulated) mode, which is a few ~100 khz. wide.

Regards, Nils
