This program doesn't support use the way you are trying to use it. This is covered in readme.md.

Look in amodem/config.py and set the environment variable BITRATE answer to one of the selections in that list (see below).

export BITRATE=80

amodem/config.py:

# MODEM configurations for various bitrates [kbps]
bitrates = {
    1: Configuration(Fs=8e3, Npoints=2, frequencies=[2e3]),
    2: Configuration(Fs=8e3, Npoints=4, frequencies=[2e3]),
    4: Configuration(Fs=8e3, Npoints=16, frequencies=[2e3]),
    8: Configuration(Fs=8e3, Npoints=16, frequencies=[1e3, 2e3]),
    12: Configuration(Fs=16e3, Npoints=16, frequencies=[3e3, 5e3]),
    16: Configuration(Fs=16e3, Npoints=16, frequencies=[2e3, 5e3]),
    20: Configuration(Fs=16e3, Npoints=16, frequencies=[2e3, 6e3]),
    24: Configuration(Fs=16e3, Npoints=16, frequencies=[1e3, 6e3]),

I don't think this is related to the original post. Looks like there is a missing dependency in your installation, or you are not using the correct version of python.
