I have not heard many comments about DEX, other than the ones that I have made. Has anyone being having some testing experiences? Good or bad?
When I first tested it against other modes some time back, I was very disappointed in the performance. I suppose this is due in part to the expectation that if a new mode is created, it should be better in at least some ways to the existing modes. When Patrick employed FEC, this did make the mode perform better for my testing as long as the QRN levels were not too severe. Of course the speed was cut in half so that speeds much slower than 11 baud were not optimum for keyboarding. I really had high hopes that this was going to be a good general purpose mode as it is also easy to tune in and not too wide and has many speed choices. My recent experiments were again disappointing because it does not seem to perform well on the lower bands with high QRN plus severe static crashes. I wonder if we could develop some guidelines for which digital modes work best with different conditions? I like to think I have a "feel" for many of these modes, but I probably don't have a very accurate picture since there are so many variables. Or maybe there is something available that is more recent than the excellent UK critique that was made of several modes a few year ago? 73, Rick, KV9U Andrew O'Brien wrote: > Would you like to see DominoEX in MIXW? > > * We need an experienced Windows sound card programmer capable of > working with Microsoft MFC and the free Microsoft C compiler in order > to build a definitive DominoEX DLL for MIXW. > > * We can offer all documentation and source code for a fully > working program (ZL2AFP's version), as well as source and compiled DLL > for a preliminary (limited but semi-working) DLL written by Denis > UU9JDR of the MIXW team.
