The band is filled with lots of French, Spanish and Moroccan stations, a mix of Tropo and Sporadic-E. Using Airspy R2 and 8-element yagi from Innov Antennas.

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.
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'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.
My second Airspy HF+ arrived today fresh from the production run, below are a couple of screenshots from BBC Radio Cornwall on 103.9 MHz. In the main photo you see the packaging!
Well worth waiting for, no-one will be disappointed.
It's nice to see SDR featured on the front cover of the 2018 ARRL Handbook - maybe 2018 will be the year of the SDR?
