fdmdv_mod - a diagnostic tool for the codec2 library to create a raw modem signal file from a codec2 bit file.
fdmdv_mod usage: InputBitFile OutputModemRawFile [Nc]
Given an input file of bits outputs a raw file (8kHz, 16 bit shorts) of FDMDV modem samples ready to send over a HF radio channel. The input file is assumed to be arranged as codec frames of 56 bits (7 bytes) which we send as two 28 bit modem frames.

The first argument, InputBitFile is the file name of a file with codec2 encoded bits. If "-" is given the input is taken from stdin.
The second argument, OutputModemRawFile is the file name of a file to be created with modem sample data. If "-" is given the output is sent to stdout.
The optional third argument, [Nc] is the number of carriers to use in the modem. The default is 14. The minimum is 2 and the maximum is 20.
