G0MQW UK QRSS GRABBER All images � Copyright G0MQW licence holder; please ask for permission before using images in publications
Near real-time monitoring of small slices of radio spectrum, concentrating on 50, 28 and 10 MHz QRSS (very slow morse) for E and F-layer, tropospheric, meteor scatter, auroral and other unusal propagation observations and experiments.
The "grabber" [a snapshot is taken every time the screen fills] uses Argo software, v1 build 145 by I2PHD, which is doing the narrow-bandwith processing at audio frequencies. I run 4 instances of the software, with three soundcards. It all runs on a Lenovo Windows 10 SSD laptop. I am also usually running WSPR receive-only 24/7 on 10 metres.
