G0MQW UK QRSS GRABBER

Near real-time monitoring of small slices of radio spectrum, usually concentrating on 28 MHz and 7 or 10 MHz QRSS (very slow morse) signals, GB3BUX 50 MHz, 49 MHz Brams or 143 MHz Graves space beacons 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 cheap Lenovo Windows 10 SSD laptop. I also run WSPR running on 10m and 30m.
