SD sets the standard for fast, simple logging and editing in the major international contests and in dozens of others worldwide. It is intended for single-op unassisted entries, and runs on any version of Windows, from Win95 to Vista, with a console-mode (text) interface. Here's the line-up of SD contest loggers. SD - Most HF Contests, 150 templates supplied. SDI - RSGB IOTA Contest SDU - UBA Contest SDC - RSGB Commonwealth Contest SDV - Many VHF Contests SDX - DXpeditions & Special Events SD supports rig control, serial and parallel keying - and integrates with WinKey to eliminate any CW timing issues caused by Windows. For USB to serial interfaces, combined with level converters for rig control and keying, microHAM has everything you'll need. SD is free and is fully working and unrestricted. It offers instant "full-screen" editing of any QSO in your log. All SD's files, including the log, are ASCII 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. SD is the only contest logger to offer the following features, in real-time, as you type individual callsign characters. There's no need to touch another key or memorise Ctrl-This or Alt-That. Dupe checking Country/Band analysis Check Partial by prefix Beam headings Advance flagging of potential multipliers Band/Mode analysis by callsign Linked database display Auto data insert (Zones and area codes) Countries Worked/Wanted by Continent

IOTA Contest SDI is recommended in the RSGB's IOTA Contest Rules, and is the only logger dedicated to this contest. No other logger compares for SO unassisted entries. SDI has been the choice of most of the winners, and entrants, since the first IOTA contest in July 1993. SDI has always been more popular than any other IOTA logger. Here are the stats for 2006. To do well in IOTA, you must work island stations because they're worth 5 times as many points. SDI sets the standard for instantly showing your band/mode status for island stations, and highlighting multiplier slots. Other loggers can't do this! Without exception, they're general-purpose contest loggers, with too much baggage and compromises from supporting other contests. IOTA is special - it needs a dedicated logger. SDI identifies country and call-area, as you type individual callsign letters, and give you a real-time analysis of IOTA islands worked and wanted (if any) for that country or call-area - for the current band and mode. When the country is an IOTA island with a single reference, SDI auto-fills the reference. SDI gives you a worked/wanted analysis for all bands and modes when you type an IOTA reference in the callsign field - there's no need to touch another key or remember function keys or multiple keystrokes. SDI is ready for the next IOTA Contest in July 2008 Install SDI - 583 kb IOTA Contest Results 2007 : 2006 : 2005 : 2004 : 2003 : 2002 : 2001 : 2000 : 1999 : 1998 : 1997 Soapbox comments about SDI for 2006 : 2005 Results Booklet (PDF) : 2001

DXpeditions SDX (SD for DXpeditions) is a DXpedition and Special Event logger rather than a contest logger. It supports SSB and CW operation on all 10 bands from 6 to 160 metres, and is similar to SD in giving a real-time country/band/mode analysis as you type callsign characters - without the need to touch any other key. SDX also offers real-time prefix checking, dupe checking, and beam headings. It supports Super Check Partial, serial and parallel keying, rig control, PTT and band outputs using standard files and interfaces. SDX is free and unrestricted. SDXCHECK is the associated post-event program to create ADIF or text logs for integration with your station log. Install SDX - 550 kb

VHF Contests SDV (SD for VHF) is free. No other contest logger can correctly track district, country and locator square multipliers in RSGB and other VHF contests in the UK and Ireland. SDV is fully working and unrestricted. Install SDV - 567 kb
