ISS Images, Dec 6 2017, 15:03 UTC

Excellent images copied from the ISS. radio is the Airspy HF+, 12 element X Yagi, satellite tracking etc. from SDR Console.

Picking up RadFxSat Fox 1B on her first pass over Cornwall, FM on 145.960 adjusted for Doppler. The initial TLE data is pretty accurate. Receiver is the Airspy HF+, antenna general log periodic for 130 MHz to 1.3 GHz.

Pirates!
Pirates!

Listening to pirates on FLTSAT-8 with the HF+. Found the FLTSAT 8 TLE data on the internet, added it and let the software point the log periodic at the satellite. First time I've ever listened to the pirates - not very entertaining if truth be told.


Airspy HF+ & NOAA 18
Airspy HF+ & NOAA 18

Overhead Pass

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.

    

    

Low Angle Pass

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.

    Here's the bladeRF 2.0 micro xA4 in action. 60MHz bandwidth, low CPU load. Still early days, but it works! For more info, https://www.nuand.com/product/bladeRF-xA4
  • Viridis Posted last month
    The viridis scales provide color maps that are perceptually uniform in both color and black-and-white. They are also designed to be perceived by viewers with common forms of color blindness.

  • Release: 3.0.2 Posted last month
    Performance Some of the early V3 code was not as efficient as it should have been - the Windows message pump was working too hard. Messages have been replaced with callacks and high-precision timers, as a result performance and CPU load on lower-powered computers such as the Core2Duo and mobile CPUs has improved, sometimes quite dramatically. Additions / Fixes Added Favourite Definition Groups. You can now have up to 5 optional sets of Favourite definitions as well as the Default. More below… Added single-tuner RSPduo support. Changing spectrum colours now updates the RX DSP pane if the pane is floating. Latest HF+ library now in use. Issues clicking on main window splitter causing areas of the display to go white (not be painted) resolved. Fixed issues setting recording options via the Program Options. Reduced Airspy / Airspy HF+ latency. Satellite custom name definitions can now be undone. Outstanding Bugs Restarting doesn’t restore the filter width, this always reverts to the default for the last used mode.   Favourite Definition Groups Select from the Defns panel in the ribbon bar, Defns is only shown if you have ...
