DigiACE V1.9 The latest and LAST version of DigiACE is 1.9 posted on 12th May 2005 as "DigiACE.zip" it has a small improvement with respect to "Access Violations" in receive mode. DigiACE uses the RDFT transmission system with some enhancements for the "New Mode", however this mode is no longer in current use. The latest system uses OFDM as originally implemented for Digital Radio Mundial (DRM) and modified to become WinDRM. WinDRM is an adaptation of the open source software (GNU) DRM compatible "Dream" project by Volker Fischer at Darmstadt University see: http://drm.sourceforge.net/ However unlike Dream, WinDRM is NOT open source which probably violates the GNU license agreement, but worse than that the following Licensed Radio Amateurs are currently banned from transmitting with the program: G3OQD, G30QD, G0AZX, F1USA, DM1IKE, and HB9MM. if you don't believe me, try to send a picture using any of these as the registered callsign! There are other programs also using the WinDRM modes, like DigTRX V3.xx and HamPal but they ALL use the same DLL (HamDRM.dll) which is provided by the same source as WinDRM so has the same restrictions. Now ALL digital SSTV transmissions are controlled by one person, not only the modes available but even the people who can use the system. Personally I think this is NOT in the Spirit of Amateur Radio but perhaps I am just old fashioned! I now realize that my contribution is neither wanted nor welcome so V1.9 is the LAST version of DigiACE as I don't want to spark off further aggression. Some might tell me to develop my own system from the open source Dream code, well I could, and I might be able to make it a little more reliable but hardly any faster. So who would use it when it is not compatible with the established WinDRM system? Many Thanks to all those who have used and supported DigiACE in the past and a special Thanks to all those who have submitted reports. Best 73's Martin G3OQD.
