Do you like NOAA images?

Here you can find atpdec and wxapt for the N900:

(wxapt is untested)

An example to decode a wav(recorded from a Noaa transmission):
------------------------------------------------------------


$ wget http://www.damside.freeserve.co.uk/miniNOAA.zip
$ unzip miniNOAA.zip
$ atpdec ./miniNOAA8.wav
$ ls *.png
miniNOAA8-1.png
$ gqview miniNOAA8-1.png

...


# If you want you could try other examples:
$ wget http://websterling.com/tsro/apt/sample.mp3

# atpdec wants 1 channel and rate 11025: (here we select the right channel -1)
lame --decode sample.mp3 && sox sample.mp3.wav -c1 -r 11025 sample.wav
# or: mpg123 -w sample.wav -r 11025 -1 ./sample.mp3
$ atpdec ./sample.wav
