How the replacement of solar panel micro inverters lead to 50 dB less QRM

Past time my focus was on resolving the interference caused by neighbors’ two solar panel installations. Last year I bought a QRM eliminator with which I, in combination with a Miniwhip active antenna as auxiliary antenna, achieved good results on a decent part of the HF spectrum. But the interference Continue reading How the replacement of solar panel micro inverters lead to 50 dB less QRM

Boost your QRM eliminator performance with an active antenna

In a previous post I did a review on the X-phase QRM eliminator. I found out that the antenna for receiving QRM, the auxiliary or secondary antenna, holds the key to optimum performance of the QRM eliminator. A single wire along a shelf in your shack is, for what I Continue reading Boost your QRM eliminator performance with an active antenna

LED lighting is probably the most sustainable way of bringing light into your life. Power consumed by LED is only a fraction of that consumed by a conventional light bulb, with the same amount of light. And what about the lifespan. A quality LED can last a lifetime. Blue-ish white Continue reading LED lights, a sustainable radio disaster
