Assorted ramblings from the developer


bladeRF 2.0 micro xA4
bladeRF 2.0 micro xA4

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

Viridis

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.


RSPduo
RSPduo

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.


CW Decoder
CW Decoder

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?

 


ICOM R8600
ICOM R8600

After a few days of programming (interspersed with cold beers) . Available for testing tomorrow with any luck.


FM Band II E's & Tropo
FM Band II E's & Tropo

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.


Direct Frequency Input

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.

  • C toggles the Centre option,
  • K toggles between kilohertz and megahertz.
  • For more options click the ellipses.


Signal History Export

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:

  • Field delimiter and correcsponding file format of comma (CSV) or tab (TSV),
  • Decimal separator of . or the separator for your locale, for example a ,.


Broadcast FM

At the request of Broadcast FM users, I've added the most common options to the ribbon bar. The image below shows what's now.

  • Stereo - enables stereo, when signals are weak mono can be preferable,
  • Partial - enable display of text even when only partially decoded, should be used in very weak signal situations,
  • PI Code - show the Program Information code,
  • Show - show the RDS text in an overlay on the waterfall.

V3 Beta
V3 Beta

After three years the first beta is available, download from http://www.sdr-radio.com/Software/Downloads.

  • 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 ...
