Normally I would have put this in the amateur listings, but there are several things here that don't belong there - such as HF FAX, ALE, DSC, ACARS.
Before I go add these to the UMC page, does anyone know of any other such apps? Remember to be listed on that page, they should have applications in fields other than just HF Ham operations (HF FAX, ALE and DSC all fall into that category)
