USB CW Paddle Interface

The USB paddle interface allows sending with an actual paddle or straight key instead of the computer keyboard. The adapter connects to a computer with an included USB-A to USB-C cable and has a 3.5mm TRS jack for the paddle / straight key connection. It has been tested on Windows, Mac OS, Linux, and Android.

  • Wiring Information - Wiring your key or paddle for use with the VBand Paddle Interface is the same as for a keyer or radio. You need a cable with a male 3.5mm (⅛”) 3-conductor stereo TRS connector on one end and whatever connectors are appropriate for your key/paddle on the other. For use with a straight key, connect the tip to one side of the key, the sleeve to the other and leave the ring unconnected. For use with a paddle, connect the tip to the “dit” connection, the ring to the “dah” connection, and the sleeve or ground connector to the common.
  • Troubleshooting - The adapter works by simulating pressing left and right control keys on a keyboard. Under Windows, you may need to disable Stickykeys if it is configured to work with control keys. If you hear the USB disconnect sound when you use the key, please contact us.
  • Important Notice - The VBand Paddle Interface is designed to be used with conventional straight keys and paddles.
