Amateur Radio Station K9DUR
Continuously Licensed Since 1960
K9DUR Voice Keyer
(Version 5.2.1)

The K9DUR Voice Keyer was specifically written to interface to PowerSDR(TM) via Virtual Audio Cable (VAC). PowerSDR is the program used with the Flex-Radio Systems line of software-defined transceivers, and VAC is a 3rd party software driver that creates pairs of virtual audio cables.

VoiceKeyer allows you to select which soundcard installed on your PC to use for sending messages. Most other digital voice keyer programs only use the Windows default sound card.

Although it was written for PowerSDR w/VAC , VoiceKeyer is a general-purpose digital voice keyer program which can be used with any amateur radio transceiver by using the PC's sound card and a hardware interface to the rig.

Operating System Requirements:  VoiceKeyer has been tested on systems running:
  • Microsoft Windows 7 (32-bit & 64-bit)
  • Microsoft Vista (32-bit)
  • Microsoft XP (32-bit)
VoiceKeyer may work, but is not supported on operating systems not listed above.
Download the installation package (Approximately 2.4 Mb)
 
Download the User Manual (Adobe Acrobat Format)

NOTE:  VoiceKeyer requires the Microsoft .NET Framework Version 3.5 SP1 or later which must be downloaded & installed separately. You may download the installation package directly from Microsoft or from this website. The file is about 237 Mb in size. If you have already installed any other software that requires Version 3.5 SP1 of the .NET Framework), then you do not have to download & install the .NET Framework again.

TIP:  I use the built-in record features in PowerSDR to record the necessary .wav files. The raw files normally need to be edited (trimmed to length, etc.) before they can be used.  I have found that Any Sound Recorder and Audacity are both easy to use and work very well. Any Sound Recorder is shareware & costs about $25 to register. Audacity is free.
