SuperSDR v3.14

Several bugs fixed, notably:

• audio buffer now works as it should, no more clicks and pops;
• pulseaudio stream now closes correctly when changing server or disabling second rx (thanks Luigi Pacella);
• private kiwis are accessible now;
• workaround for hamlib bug vfo a/b and cleaned some code;
• fixed the EIBI labeling behavior;

New features:

• QRZ.COM lookup now on by default within the logger;
• dynamic window resize;
• added ADC overflow indicator;
• improved visuals.

--> Windows executable added

SuperSDR v3.12

Several new features and bug fixes.

Windows executable attached as zip file.

SuperSDR v3.11b

Improved Logging subsystem with previous QSO lookup and QRZ.com automatic info retrieval.

SuperSDR v3.11

Hi,
big release for a smallish 0.01 version difference!
I just added the Logger subsystem so you can log new QSOs interactively and search for old ones.
It saves data in a simple and human readable/editable log file: no databases! Even if you have a log with 100K QSOs it will be something like 10MB...
The graphical interface has been optimized and several small bugs corrected: now the red/green colors of the MAIN/SUB RX make sense.
There is still something to do when CAT is active.
The logger dialogs use TKinter, so a new dependence... sorry, it would have been really ugly to implement them in SDL/PYGAME from scratch.
I'll convert the KIWI selection dialog too in the near future.

SLOW/FAST tuning mode is now usable by pressing CONTROL/SHIFT and the arrows.
I also lowered the CW pitch to 500Hz, if you don't like it, just change the constant value in the utils python file ;)

Enjoy!

SuperSDR 3.1

Hi,
this version should be stable.
I fixed bugs regarding:

• the memory system,
• the audio recording system,
• the audio buffer size, and the desyncing over long times due to fractional audio sampling of the kiwis,
• much improved DXCLUSTER client and spot management/visualization (new colors showing spot age),
• new command line option to increase window size (1920 goes full screen),
• deep code cleanup,
• sub-khz resolution for command line frequency,
• improved s-meter behavior.
• added the possibility to disable the DXCLUSTER client without losing the accumulated spots (P shortcut).

Enjoy!

SuperSDR 3.0 beta

Hi!
New relase!
Test it please!

SuperSDR v2.1

Hi!
Introducing several new features and bugfixes.

• The main new feature is dual receive from the same or from two different kiwis. To activate it on the same kiwi, just press Y at runtime, pressing Y again switches A/B VFOs. You can independently change all RX parameters and audio volume. To turn off the second receiver, you may either press M to mute it or press SHIFT-Y. To activate the 2nd RX from a different kiwi, just press Q (to select a different kiwi) and it will be stored in the permanent Kiwi repository saved to disk. Now that your different kiwi is stored with a number, lets's say NUMBER 1, you can activate the 2nd rx by pressing Q, then R1 and ENTER. Now pressing Y will contact the nr. 1 receiver and open it as the 2nd rx;
• Another cool feature is temporal averaging to detect extremely weak signals (a bit in the spirit of Leif Asbrink's LINRAD): you may increase (G key) or reduce (H) the averaging. Keep in mind that an averaging of 100X produces a frame rate of one hundredth, so it may be useful to monitor the band for an extended time;
• Colormap fine tuning: up to now the colormap was automatically and dynamically set up. For most applications it was fine, but to really exploit the averaging you can now change the upper (lower) limits by pressing , and . (+ SHIFT respectively). This parameters are visible in the upper left part of the spectrum.
• DX cluster is now much better integrated and the graphical presentation is much better;
• Click and drag tuning on the spectrum display, with visual freq shift indicator.

SuperSDR 2.0: new visual interface and several new functions

In this release I fixed several bugs and unintended behavior, entirely reviewed the interface, added the panadapter on top of the waterfall, added the audio recording feature and the possibility to change kiwi server at runtime and at the start.
Please let me know of any bug you find!

Thanks!

SuperSDR 1.1

This release features several new features and bugfixes.
The code has been thoroughly refactored following a more object-oriented style even if there is still a lot of work to do.
The user can now choose at runtime which operating mode to use: SYNC or not.
SYNC means that CAT and KIWI tuning are linked and every change on the real radio or the supersdr interface will change the other.
Disabling SYNC frees the CAT VFO from the KIWI RX frequency/mode and the waterfall continues to work as a panadapter for CAT and the KIWI RX will act as a second receiver on a monitor frequency. The two receivers are resyncable to converge again on the same freq.
Memories are now implemented as a circular buffer: you press W and store, press R repeatedly and you cycle through them. 10 memories are available, the oldest will be erased if you store more than 10.

We also feature a new Windows release
