and ``aprs``\n=================\n\nLibrary to generate Bell 202 AFSK audio samples and \nAFSK encoded APRS/AX.25 packets. \n\nThe ``aprs`` command line program encodes APRS packets \nas AFSK audio data. \n\ne.g.::\n\n    $ aprs -c \u003cyour callsign\u003e \":EMAIL    :test@example.com Test email\"\n\nInstallation\n------------\n\nInstall with ``pip``::\n\n    $ pip install afsk\n    $ pip install --allow-external PyAudio --allow-unverified PyAudio PyAudio\n\nPyAudio is optional, so must be installed separately. \n\nIf you want to use the CLI program to play APRS packets via your\nsoundcard, install PyAudio. Otherwise, if you just want to generate\nWave files of AFSK data, you can skip it. \n\nNote that installing PyAudio will require a C compiler and PyAudio's various\nC dependencies, in addition to the ``--allow-external`` and ``--allow-unverified``\n``pip`` flags. \n\nFor development, change to the afsk directory and install with::\n\n    $ pip install -r requirements.txt\n    $ python setup.py develop\n\nRequires Python 2.6 or 2.7.\n\nCommand Line Interface\n----------------------\n\nGenerate APRS messages with the ``aprs`` CLI program::\n\n    $ aprs --callsign \u003cyour callsign\u003e \":EMAIL    :test@example.com Test email\"\n\nSpecify your message body with INFO command line argument. Be sure to wrap the message in \nquotes so it's passed as one argument, spaces includd. \n\nAt the moment, no message formats are implemented in the ``aprs`` program; you must \nconstruct the body string yourself. For instance, in the example above, the string \npassed as an argument to ``aprs`` follows the email messsage format specified for APRS. \n\nYou *must* specify your amateur radio callsign with the ``--callsign`` or ``-c`` flags.\n\nUse the ``--output`` option to write audio to a Wave file (use '-' for STDOUT) rather \nthan play over the soundcard. \n\nGet a listing of other options with ``aprs --help``.\n\nExamples\n--------\n\nPlayback with PyAudio and short options::\n\n    $ aprs --callsign \u003cyour callsign\u003e \":EMAIL    :test@example.com Test email\"\n\nPlayback with ``sox``::\n\n    $ aprs --callsign \u003cyour callsign\u003e --output - \":EMAIL    :test@example.com Test email\" |\\\n          play -t wav -\n\nSave to a wave file with using short options::\n\n    $ aprs -c \u003cyour callsign\u003e -o packet.wav \":EMAIL    :test@example.com Test email\"\n\nContributing\n------------\n\nGet the source and report any bugs on Github:\n\n    https://github.com/casebeer/afsk\n\nVersion History\n---------------\n\n- 0.0.3 – Pin dependency versions, fix bug with STDOUT playback, verbosity CLI option. \n\n","funding_links":[],"categories":["Other SDR Software"],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcasebeer%2Fafsk","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fcasebeer%2Fafsk","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcasebeer%2Fafsk/lists"}
