A bit of Radio Astronomy last night monitoring the Orionids meteor shower. If you listen on 143.049Mhz (upper sideband)you should be able to hear ‘pings’ from the GRAVES transmitter in France reflected from incoming meteors. The ‘pings’ can be seen visually on a computer by downloading ‘SpectrumLab’ and taking the audio from your receiver into the soundcard.

The picture shows ‘pings’ from last night on SpectrumLab using my Yaesu Ft857D and VHF collinear.
