Still early days - testing the connection between Cornwall and North Carolina. Streaming IQ data, working well. Enjoying the AM transmissions on 80m.
In total nine of the twelve were copied during the afternoon passes on December 7th and 8th 2017.
Excellent images copied from the ISS. radio is the Airspy HF+, 12 element X Yagi, satellite tracking etc. from SDR Console.
I spent a day working on transmit support for the LimeSDR. This is by no means finished, but I'm able to say that it works. I have a few problems,
The above are down to my own software, so I'll give myself a good kicking sometime and get this fixed later in 2017 or early 2018.
Here we see the Upper Sideband (USB) signal as received with an Airspy HF+.
And here's the TX panel 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.

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.
Data processing at 1,343 megabytes / second from a NVMe SSD card.
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.
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.
