14 January 2020 – QRM Guru Plans for 2020

It is almost 16 months since RASA decided to do something about QRM and RFI.  At the time, we had no idea what that “something” would look like.  But thanks to our members, and over 20 contributors, QRM Guru has become a useful resource to assist radio amateurs in identifying and minimising QRM.

QRM Guru was first released at PerthTech in March 2019.  Since then the QRM Guru team have:

  • posted sixty articles on identifying and resolving QRM;
  • presented QRM Guru at 12 clubs and hamfests across five Australian states;
  • donated ten QRM Kill Kits to radio clubs (estimated retail value of ~$200 each);
  • developed nine videos explaining how to use the tools and techniques;
  • posted eleven case studies from real world situations from your fellow VK hams; and,
  • invested almost $1,300 in QRM Guru (web site and QRM Kill Kits).

This year our goals for QRM Guru are:

  • make QRM Guru easier to use for newcomers and non-technical users;
  • investigate how we attack new sources of QRM/RFI;
  • seeking cooperation with more clubs, especially the larger state based clubs;
  • donate another ten QRM Kill Kits to clubs;
  • visit at least six clubs; and,
  • seek closer cooperation with the WIA in promoting QRM Guru.

Donating QRM Kill Kits and presenting to clubs are our largest expense.  We welcome financial donations to help us deliver and improve this resource.  Please contact us if you’d like to donate.  Every little bit helps.

Are you a Foundation Licencee, or newcomer willing to help us make QRM Guru more user friendly?   You don’t need any special knowledge, other than a desire to learn and experiment with QRM Guru tools & techniques.  Please send us an email if you’re willing to assist.

Next.  Do you have a deep knowledge or professional experience with electrical engineering and/or RF technologies?  If so, and you’re willing help, please contact us.  We’re looking for people to assist us in investigating and developing strategies to address new and emerging RFI generating technologies.

Please email us if you have any suggestions or requests for QRM Guru in 2020.  Also, if your club would like a presentation, please send us an email.

Our email address is info@vkradioamateurs.org.
