march 2013 : V1.00
A new version of EhoCW is out, with a lot of differences compared to previous 0.92
- The portaudio low level library sound is now used by EhoCW, this enables to use the Windows 7 WASAPI library, ASIO, DirectX, and so on. The best latency results are obtained with ASIO with an ASIO sound card or with the ASIO4ALL driver wich enables many sound cards to be used with ASIO.
- If you don't want to use ASIO, then choose WASAPI in the option screen.
- The morse decoder has been removed from this version, but for those who liked it, you can download (or keep) the previous version. The decoder is now a new project, and will be ported from Borland C++ to Qt C++ technology, and will be multi platform (Windows, Mac, Linux).
- It is now possible to connect one or two double keys plus one or two straight keys (with com ports).
- The sound generator has been improved, there is no more 'clicks' in the morse sound. This has been intensively tested by Chuck AA0HW, and the signal is very nice with no harmonics at all. Chuck also made some videos published on youtube and on his website (http://qrqcwnet.ning.com/), the videos are available at :
