MultiMode allows your Macintosh to decode and transmit several different
modes of non-voice communication often heard on shortwave radio.

In the past, dedicated hardware, often costing hundreds or thousands of
dollars, was necessary to demodulate and decode this transmissions. Today,
you can use the processing power of your Macintosh to decode and display
these modes, without any additional hardware, other than your Mac and a
radio.

MultiMode supports the following modes:

       Morse Code (CW)
       RTTY (Baudot)
       ASCII
       SITOR-A
       SITOR-B / FEC / NAVTEX
       SSTV (Slow Scan TV)
       WEATHER / SATELLITE FAX
       ACARS (Aircraft Communications)
       Packet
       PSK31
       ALE (Automatic Link Establishment)
       DTMF, CCIR, EIA Tone Modes
       Hellschreiber
       Audio Spectrum Display / FFT Mode


Requires a PPC Macintosh
