CW Run QSOs: A CW Contest Simulator

The simulator for the weekly CWT contests sponsored by CWops, has been reworked including the following:.
  • Support for the ARRL DX, ARRL Field Day, ARRL Sweepstakes, NAQP, CWOpen, WPX, and the Bill Windle QSO Party has been added.
  • The simulator hardware has been modified to use an Arduino Nano.
  • A printed circuit board has been developed and is now available to improve constructability.
  • a 3D printed enclosure has been developed and is now available as an STL file
Similar to the previous version, the Nano is used as the Morse generator under the control of a PC application that is responsible for logging, grading the user, and keeping a historical record..

Constructing the Simulator - Construction of the simulator is straight-forward using the supplied PCB and associated parts. Soldering of the headers for the Nano, and sockets for the digital potentiometers and op-amps takes about an hour, as described in detail in these Construction Notes.

Quick Start Guide - Once you have constructed the simulator, the final installation can be completed using this  Quick Start Guide.

Using the Simulator - To operate the Simulator the user performs a set of configuration steps which involve connection to the Arduino, creation of a pool of potential callers, definition of information about the user's operation (call, name, number, etc.), and definition of the type of session the user wishes to run. All of these steps are performed from the user interface on the PC as described in detail in these User Notes.

Download the Package - To begin the download of the latest version (2.0.06) click on this link CWRunQso-2-0-06 Download Package  and elect to save the file to a directory of your choosing.

Unzip the Package - Once the download is complete unzip the package. This will result in two files:  the setup exe and the Quick Start Guide.

Install the software- Run the setup exe file to install the software. The setup exe will install a full version of the software so you can either uninstall any previous version or you can just install the new version on top of the existing one. .

Support - Once the PC side of the software is installed you can access the user and construction notes from the Help menu. If you continue to have questions after reviewing these notes feel free to contact me via the email link provided on the CQ/X Support page.

Updates - There are currently no updates to Version 2.0.06 but once revisions are made they will be available here.
