The above is very useful for dual diversity when you have two 
independent receivers fed from two independent antennas, but you can 
also run multiple copies of MMTTY from the usual receiver's single 
mono audio stream. Each copy can use different decode parameters if 
you like. Just park them on different spots on the screen and have at 
it. I routinely do this, and each copy only adds about 2% to my CPU load.
