| SWM MAY 2004 Radio Reflection Detection Andy Smith G7IZU (Plymouth) has a couple of receivers rigged up to continuously monitor 48.250MHz (Channel E2) and 55.250MHz (E3) in s.s.b. mode, listening for Meteor-Shower, Aurora and Sporadic E signals. A simple dipole and pre-amplifier feeds the receivers, which are fed into a PC audio card. The PC is running two copies of DL4YHF's Spectrum Lab, which creates 'live' FFT plots of the audio spectrum which are then uploaded onto Andy's web pages. On the main 'live' page you see an FFT plot of the previous ten minutes, plus a signal-level trace over the same period. Reflections of meteors, Sporadic-E and auroral events show up as lines and pings on the plot, only lagging real time by a minute or so. On another page there are plots created by the second FFT showing six-hour views from the past 24 hours. Anyone interested in a confirmation of Band 1 activity should view the website at www.tvcomm.pwp.blueyonder.co.uk/G7IZU_Radio_Pages/Radio [Note: this link is now invalid - A.S.] The site also has various archive capture and analysis pages. |

SWM SEPTEMBER 2005 Computers and Radio (Part 4a) An article by Jack Weber highlighting the uses of Spectrum Lab and other FFT programs for the monitoring of meteors and other man-made signals. To respect SWM's publication date, I'll with-hold re-publishing the text for a few weeks. |
