Some further observations on the WaveTool utilities.
1) These are actually 16-bit Windows 3.1 programs, but they work well on 32-bit Windows 2000 and Windows XP systems. They will NOT work on Windows Vista or Windows 7, since the 16-bit compatibility layer (a.k.a. the "thunker") that has existed in 32-bit Windows since Win 95 was quietly dropped in Vista and beyond.
Note that this breaks many older supposedly 32-bit programs. Many early Win95/Win98 "32-bit" programs contained chunks of 16-bit code (especially device drivers) recycled from their 16-bit Windows 3.1 predecessors. Such programs depend on the thunker to seemlessly run the mix of 16- and 32-bit code.
2) Windows XP allows multiple applications to access the sound card simultaneously. The WaveTool scope or spectrum analyzer can run AT THE SAME TIME as the AGW Packet Engine, APRS Messenger, mmSSTV, MixW or other other sound card app for a REAL TIME display of the incoming signals being fed into these apps.
3) The WaveTool scope in dual-trace mode can do the tricks "real" scopes do of displaying A-only, B-only A and B, A-B, A+B and A vs B vector displays.
