SD is shareware, try it before you buy it), with registration options starting at 10 euros. When you register, you get a key file by email. The key file, SD.KEY, will never expire, and it activates the current version. If you choose the 12-month registration option, your key file will activate any later version downloaded within the next 12 months. Any version that works with your key file will keep working, with no time restrictions, when used with your registered callsign in the presence of the key file.

Features

SD supports rig control, serial and parallel keying - and integrates with WinKey to eliminate CW timing issues caused by Windows. microHAM's USB CW Keyer offers WinKey and level converters for rig control in a single package.

SD offers instant "full-screen" editing of any QSO in your log. All SD's files, including the log, are standard ASCII text files and can be viewed with any text editor.

Following any QSO edit, no matter how complex, SD checks your complete log for consistency, and instantly updates all relevant QSOs.

This includes setting and unsetting dupe and multiplier flags, and updating area codes (zones), and points, in all QSOs as required. The information shown in the Summary Score window is correct at all times. Just try this on any other contest logger - and see the difference for yourself.
