That of course begs the question about what other software supports ALE. MultiPSK did at one point, but according to the last URL I had, looks like that capability was dropped as of v3.9. The only other software- and it's a bit expensive, but the rep is very good - that's a possibility is SkySweeper at:

They have their own Yahoo group - I would suggest Vista operators ask before purchasing. And perhaps with a little prodding, Charles can be persuaded to change his position on PC-ALE. It's way too popular a free package to leave folks out in the cold.
If there are other packages that cover this mode, please let us all know
