Andy,

Does anyone have a programme to repeatedly play .WAV files in a
continuous loop ?  This will not be ideal for 'Coherent' data testing,
as there will be a discontinuity at the wrap round point that will
necessitate re-syncing, but is better than nothing.<

... look for a shareware called Cool Edit 2000, it comes with limited
features unless you pay for it, but it will do what you plan. It is a very
good graphic type editing file for all kinds of audio files. I use a
(licensed) copy to edit the music files we create (see www.piperswine.de
-hi-), but also for exactly what you plan to do, sending WAV BPSK files in
a loop.
