I use Bonito radiocom 4.5 icom software for receiving weather fax broadcasts on hf .
here is a video of seaTTY program being used( availible for download on the web) and what wefax sounds like on the radio... you'll see the wefax pic about 50 secs into the vid. >>>>>http://www.youtube.com/watch?v=SAHuNwxq0L0
there are other programs out there is is just one of them.

Ive even copied one or two foreign fax broadcasts too using the bonito pgrm
normally all you have to do is feed the audio into your pc, start up the program and configure the audio settings so the program can hear the radios audio
there maybe some additional settings to be made but Im sure the programs help file will get you started listening/seeing wefax broadcasts pics.
