Here's a screenshot of the version 3 Analyser slowly taking shape. This is a zoomed processing on 963kHz taken from an overnight recording, we see many medium wave (MW) carriers present.

Here are pictures of the SDR-Radio.com offcie / playroom / shack.
Here's an example of the HF+ receiving the NOAA 18 APT weather satellite, the antenna is a log periodic covering 130 MHz to 1.3 GHz. The HF+ is very sensitive and very quiet - no mixer products, spurs, or artifacts at all.
Here's an image from NOAA 18 but a moch lower angle - 13 degrees. You see noise on the image, but nethertheless an excellent copy.
The original CW Skimmer implementation missed an importrant feature, namely:

Amateur radio operators on 80m. Recorded using a NetSDR and Wellbrook loop antenna.
Good to see SDRs being demonstrated at the 2017 RSGB convention, just wish I were there. Photo from a post on the ML&S facebook page.
Lots of keyclicks on 20m!
