Thread: Hydrogen Line receiver Radio

nothing to display

No problen....You can buy a receiver no bigger then a USB memorystick called Funcube dongle pro. Completer receiver from 50MHz to 1700MHz! It wil receive all modes. But you only get a 96kHz slice of the spectrum at any givin time. I got one and it works nice in receiving the hydrogn line. You can hear the hydrogen noise in you pc speaker...awsome!
But you still need an antenna and a low noise amplifier. My antenna is a simple tiny Horn antenna....see the SETI site and look for "The horn of plenty" antenna project. They also sell LNA's that work at the hydrogen line frequency.

Look at my results using a shortwave receiver and down converter to servay the hydrogen line... [DOC]
