YouTube user Chris D has posted a video showing Gqrx in action on his Raspberry Pi equipped with the 7″ touch screen. Chris uses an rtl-sdr dongle with what appears to be a home made upconverter.
Meteor scatter, or meteor burst communications, is a challenging field within amateur radio communication, where the operators use the ionized trails of meteors for reflection of radio waves.
George Smart, M1GEO, has posted a very nice write-up on his website describing the setup that he uses for meteor scatter reception. The setup uses an RTL-SDR dongle with Gqrx as receiver, and WSJT or MSHV for decoding.
