G0MQW UK QRSS GRABBER

Near real-time monitoring of slices of radio spectrum, usually concentrating on 28 MHz and 10 MHz for E and F-layer, tropo, meteor scatter, auroral and other unusal propagation observations and experiments. During major meteor showers this site will monitor for radio reflections from areas of ionisation in the ionosphere caused by meteors.
The "grabber" [a snapshot is taken every time the screen fills] by the software, Argo v1 build 145 by I2PHD, which is doing the narrow-bandwith processing at audio frequencies.


Location: IO91ml, Reading, Berkshire, UK.

STATUS 18 May 2018.

At times I add audio recordings in 2-minute .wav time coded files of Grabber C, to give audio of incoming meteor trail reflections of the BRAMS beacon when looking for correlation with 10m and 30m grabbers. These radio-based images of reflections appear as blobs, little squiggles or massive splashes. You can sometimes see that the meteor has broken into pieces creating multiple traces. They travel at different speeds and the frequency shift is due to Doppler Effect. You may see a characteristic epsilon shape (a reverse 3) or a hook, as the meteor itself encountered turbulence. There are AUDIO recordings in the archive folder of this Grabber. Link to BRAMS website
