NAME

       fdmdv_mod  -  a  diagnostic  tool for the codec2 library to create a raw modem signal file
       from a codec2 bit file.

SYNOPSIS

       fdmdv_mod usage: InputBitFile OutputModemRawFile [Nc]

DESCRIPTION

       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.

EXAMPLE

        fdmdv_mod hts1a.c2 hts1a_fdmdv.raw

OPTIONS

       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.
