Here's the bladeRF 2.0 micro xA4 in action. 60MHz bandwidth, low CPU load. Still early days, but it works!

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. [link to ggplot2]
Here's an example of RTTY in action with version 3.0.3 (not available yet), click for a full-size image.
I've always wanted to write a CW decoder from the ground up, a decoder which is as good as the human ear and possibly better. A week ago I started this project as an add-on for V3, the deocder is working but there's a long way to go. It'll probably be available by the end of August, for now here's a taster decoding the NQY (Newquay airport) beacon on 347kHz. Note: this is a development window with extra data to help get synchronised and extract real signals from the noise.
Who knows, maybe add some AI as well?
After a few days of programming (interspersed with cold beers) . Available for testing tomorrow with any luck.
Version 3.0 was started on February 28th, 2015 at 07:43. Many hours of coding later and I'm able to release 3.0. Check this blog for the status of 3.01, new features, fixes etc.
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.
You now enter a new receive frequency by simply entering 0 ... 9 or . (period). As soon as you start typing the Frequency window is displayed.
The signal history is selected from the View, Spectrum pane in the ribbon bar, the data is exported by selecting the ellipses button.
In the Export window you now select:
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.
