The hands-on software for passionate CW and SSB contesters. It contains the world-unique synthesized voice keyer.
No need to record anything into your voice keyer!

HamRacer main window:
Cheap, yet a very mature interface for the
highest demands:
Spider Keyer:
Null Keyer. The most simple interface to provide
CW keying and PTT control:


Tom, KC0W: Super easy to use & understand. Very intuitive. I glanced over the manual after I had already been using the program for 45 minutes or so.
Layne, AE1N: Your software has the promise of a breakthough in Ham Radio SSB contesting...
Marty, W8AKS: Happy, am I happy, see the footprints on the ceiling! Beautiful job!  This has been needed for a long time. ... This puts the fun back into SSB contesting for me.
Mike DH6JL/DK6M: It is a wonderful tool when the family sleeps and i'd like to make some talks to friends via air. The free type/talk option is a nice way to talk with people and keep the rooms quiet.

Version history (last entry first)

Version Date of Release Changes Remark Not yet HamRacer can speak two languages now. The main language (always English) and the 2nd language (your choice). It currently supports Czech as the second language but it can be easily configured to speak any other language, too. The language selection happens automatically in dependency of the callsign input.
Enhancements in Synergy (e.g. you can prohibit the connected HamRacer to delete or modify QSOs in your log). May 16th,
A new menu option: New As...
Minor fixes and enhancements. May 14th,
Specifying of multipliers enhanced.
A new version of the sketch for Spider Keyer: 1.17 - a bug fix - a smoother transition from automatic sending to manual sendiing.
Tested in OK1WC memorial contest. Apr 12th,
A new wizard Adjust Audio Levels.. will help you to set correctly all levels for the synthesized voice keyer.
A new version of the sketch for Spider Keyer: 1.16
Tested in OK-OM DX Contest SSB Apr 8th,
This version finally implements a feature required by many:
CW keying and PTT control through DTR and RTS signals on RS232 (COM port, virtual COM port).
Even that the prefered way of interfacing is
Spider Keyer, the DTR/RTS approach can still be a good choice for some.
A new version of the sketch for Spider Keyer: 1.15
Thanks go to Tom KB9ENS for his professional tests and comments. Mar 27th,
Improved DUPEs handling.
The New Contest wizard can be now used to modify the properties of the current contest, too.
The location of configuration files and sample logs has changed. The change will be mainly appreciated by those who log into the Windows as Users and not as Administrators.
This time, exceptionally, it is recommended to unstall the current version (ver. or older) and then install the new one (ver. or newer). If you have made larger changes in configuration that you would like to preserve, before uninstalling, copy aside the file HamRacer.cfg. After installation run HamRacer to create a new HamRacer.cfg with default values. Finally, replace this HamRacer.cfg with your original one.
Thanks go to Jindra OK4RM for discussion on system folders in Windows Mar 4th,
