The QRM Guru Process

Our introductory videos

If you’re new to the hobby and not sure where to start visit this page.

Much of the content has been derived from various sources, including the public domain, published works and project work by developers and VK radio amateurs.  All references to published works and project work are acknowledged.

The objectives of QRM.guru are to provide an integrated online educational resource to assist all Radio Amateurs in:

  • better understanding RF noise sources that impact on their enjoyment of the hobby;
  • providing a series of tools, techniques and guides to assist in locating and reducing or eliminating noise sources;
  • providing guidance on how to select consumer devices that comply with regulations and do not emit unwanted RF noise;
  • encouraging radio hams and clubs to collaborate in reducing noise and promoting the hobby;
  • developing and utilising our technical skills to resolve issues that impact on our enjoyment of the hobby, even when the interference is not of our responsibility;
  • assisting VK Amateurs in getting more enjoyment out of the hobby.

Users are invited to provide feedback and additional content to make this resource more useful for all radio hams.  If you have any case studies, methods or experiences that may add to the overall value of QRM.guru, please send us an email with details.

Whilst QRM.guru has been developed in VK, it will be of use to hams worldwide.
