Observing Lyrids: Lichfield Radio Observatory's Radio Signals on 21/4/12

On April 21st, 2012, the Lichfield Radio Observatory captured radio signals from the Lyrid meteor shower. Despite a frequency drift, tuning into Graves Radar at 143.050MHz revealed an increase in signal strength. The data, although not typical of meteors on Spectrum Lab, offered intriguing insights. This study involves comparing the observed signals with internet-sourced data and human voice traces picked up by a laptop microphone.

  1. Radio Observations of Lyrids21/4/12 Lichfield Radio Observatory

  2. Tuning into Graves Radar143.050MHz – although tone is picked up below this – 142.975Mhz on 21/4/12 but drifted during evening. Signal strength increases when tune into tone

  3. Have I picked up meteors here?

  4. However usually meteors on Spectrum Lab appear as below: These are not Lichfield Radio Observatory data but comparison pictures from internet

  5. Spectrum lab settings I used

  6. Compare with a tracing of human voice picked up with the microphone in the laptop
