GDX: DX Cluster viewer for GNU/Linux

I would receive DX cluster sposts and easly filter them, without writes commands on a telnet console. So GDX was born.
This application, written in C with GTK 3, connects to the remote server and receive all spots; if a filter is selected it is applied only on display, but all spots are received and could be showed afterwards.




 You can find it on GitHub

CQhana


CQhana was written in order to enrich the excellent CQRlog, an advanced hamradio logger for GNU/Linux, that can be connected directly to the rig.
CQrlog has some statistical functions, but what I need, is a global log analysis, for check the trending of my QSO.

So was born CQhana, a simple shell script, that extracts data from CQrlog Mysql database and make some sintetic graphis, reporting the result to a PDF file.

Below, some example:




You can download it from sourceforge.net 

Download CQhana
In order to execute CQhana, you need to start CQrlog before and gnuplot 5.0 (or greater) must be installed on your system.

Arduino CW Decoder

Since I've an Arduino Uno, bought some time ago, now I decide to build a CW Decoder, to use with my radio

I was inspired from other similar project on the net, first of all this:
http://skovholm.com/cwdecoder

and also from this:
http://iv3ogt.altervista.org/Homebrew/cw_decoder/ 

The core of the software is the Goertzel algorithm, that decodes the audio signal (it's not my own work), to which I've added the TFT 1,8'' interface. On the screen you can see all the decoded letters, the WPM and the audio signal graph.


The circuit

You can download the Arduino sketch from here:
Download IU1BOW CW Decoder





The box is orrible!... but it's only a prototype :-)

Next steps

I've some ideas to add a keyboard to the project, in order to coding and send the morse code.
The options are:
- interfacing with bluetooth to Android and input from cellphone virtual keyboard
- mini ps/2 keyboard
- change this video with another touchscreen, in order to simulate a keyboard

AV-640

Here my new vertical antenna  Hi-Gain AV-640


I'm trying it... good, but not excellent... also because the room is little; it would be better to place the antenna in an open field!
