A Python tuner for digital modes on Ten-Tec Orion

I've been using this little control panel (opsk) for some time now. Maybe it's time to release it for any other Orion/Linux/Python/PSK addicts out there. This app lets you select the HF band you want to use, tune the antenna if necessary, and control the passband to zero in on a PSK signal you see on your waterfall display.

It uses TKINTER and pySerial technology.

Python Tone Generator

A new Python-based Tone Generator application is available from the AA6E software library at www.aa6e.net/aa6e/software/tone. It was a learning exercise for me to get acquainted with the wxWidgets cross-platform library for software development. We are also using the wxPython library that provides a Python "wrapper".

The present version is for Linux and Unix only, since it makes use of the OSSaudiodev module for sound generation.

Tone will work with dual soundcards, and will provide single or dual tones with sine-, square-, or triangular-waveforms. It can be useful for many kinds of system tests, including intermodulation distortion.
