Successful QRM / RFI (Radio Frequency Interference) Tracing!

A pre-planned local area power outage gave me a rare opportunity to experience my local HF noise levels without local interference. Even though this outage only covered a few roads around my house and a limited number of properties, the impact was incredible! I heard New Zealand for the first time from home 😀 It also highlighted a significant amount of QRM, particularly a strong 70KHz repeating signal across all the HF bands. In this video filmed on New Year's Eve, I build a simple non-resonant RFI/QRM loop antenna and use it to track down the location of the interference. Despite looking rather odd wandering around the local area looking as though I was detecting bats or something, it was good fun and in these times of social distancing, caught the interest of local passers-by with whom I chatted and explained what I was up to 😀. All were intrigued and one had even heard of RAYNET! My thanks to The Radio Amateur Society of Australia Inc. for the antenna design.
