Qtmm souncard modem decoding APRS data from the ISS

Yesterday I successfully received APRS transmissions from the International Space Station on 145.825 MHz using my Yaesu FT-817 connected to my MacBook Pro via a Signalink audio interface and a USB sound adapter.

Qtmm soundcard modem for decoding AFSK1200

Last week I started on a new experiment trying to integrate the AFSK1200 demodulator code from multimon into a simple Qt-based graphical application. This experiment had two objectives:

  1. Test the feasibility of integrating the AFSK1200 demodulator from multimon into other applications.
  2. Try using the QAudio framework from Qt for audio I/O that should work on both Linux, Windows and Mac OS X.

Qthid 3.0 for Windows

The Qt-based Funcube Dongle Controller is now also available as a windows binary package – thanks to Mike Willis G0MJW and David Barber G0OQW who have been trying to build it until we eliminated the two build issues (one of them was my fault 😉

Qthid 3.0 with full API support released!

Qthid 3.0 – the Qt-based controller application for the Funcube Dongle – has been released. This release includes support for the full control API available with the 18f firmware for the Funcube Dongle. This should cover all the functionality provided by the “fully functional windows front-end”.

Qthid Funcube Dongle Controller

Qthid is simple cross platform controller application for the Funcube Dongle Pro and Pro+ software defined radio receivers. It is written using the HID API library and the Qt GUI toolkit. It is a fork and evolution of the qthid002.zip package by Howard Long, G6LVB, available on the Funcube Dongle download page.

Qthid 4.0

Qthid is free (libre) software licensed under the GNU General Public License. This allows you to copy, modify and distribute the software without any restrictions, provided that your modification are distributed under a compatible license.

Status

The current stable release v4.0 provides full support for the Funcube Dongle API available with firmware 18f or later:

  • Change frequency and apply frequency correction.
  • Change RF gains and filters.
  • Change IF gains and filters.
  • LNA enhancement, bias current, etc.
  • I/Q correction.
  • Auto-repeat tuning buttons (click and hold button to scan).
  • Variable frequency step.
  • Upgrade and verify the firmware.
  • The crashes and freezes in the original qthid002 have been eliminated (I hope).
  • Tested on Mac OS X and Linux (32 and 64 bit).
  • Use of v3.0 and later requires firmware 18f or later. Use v2.2 to upgrade earlier firmwares.
  • Works on Mac OS X 10.7 Lion and Windows 7.

There is also a quick-hack release v4.1 that supports the new Funcube Dongle Pro+ devices. This does not work with the original Funcube Dongle Pro!

Qthid 4.1 for Linux

Download and Install

If you are using Debian or Ubuntu Linux you can try to install the Debian package available for wheezy (testing) or sid (unstable). These packages contain everything to set up and configure your Funcube Dongle.

For other systems you can try my pre-compiled binary packages available in the download section at SourceForge. You will also find source packages there. Regardless of which option you try, be sure to read the README.txt file.

The latest development code is available directly from my Github repository:

  git clone git://github.com/csete/qthid.git

(Note that in order to get the Pro+ code you need to switch to the “fcdpp” branch.)

If you have a Github account you can fork it directly in Github and our repositories will be part of the same network. See the Pro Git manual for other awesome things you can do with the git repository.

Help and Support

I recommend to use the FCDevelopment Yahoo group if you have an original Pro device or the FCD Pro Plus Yahoo group if you have the newer Pro+ device. Pretty much everybody who knows something about the Funcube Dongle and the software API is there. Alternatively, you can post a comment to this page. I any case I prefer public forum for troubleshooting so that there is a record for future reference.

Improved search in the Gpredict saetllite selector

Charles AA1VS has done some cool tweaking to the search functionality in the Gpredict satellite selector. Check out the video below to see how it works.

CuteSDR – Open source SDR for Linux, Mac and Windows

CuteSDR screenshotIt looks like Moe Wheatley, AE4JY, is working on a cross platform software defined radio receiver intended for SDR hardware from RFSPACE. It is written using the Qt toolkit and will be available soon under an open source license with the purpose of providing an SDR interface program example for other developers. It is still very early and no code has been released yet, but you can watch this first demo video published few days ago and you can also join the CuteSDR Yahoo group if you are interested in following the project.
