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.
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.
Select from the Defns panel in the ribbon bar, Defns is only shown if you have enabled one or more definitions groups.
In the Organiser select the Definitions, click … to define groups (top of window, see below).
I just spent two days getting the RSPduo integrated with version 3.0.2 using the RSP specification 2.13. So far, so good - works well.
Aiming to release 3.0.2 which has fixes and extra Favourites features.
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.
