Series: RFI Cancellation Shootout

We compare the performance of leading analog RFI reduction produces: NCC-1, ANC-4, MFJ1026, X-Phase

Analog Noise Reduction Showdown

Dreams come true. I have been able to assemble four leading analog noise reduction products for comparison, real world and lab testing. Read more

All 4 of my test units attacked worst case wideband RFI successfully, but the performance of the cheap X-Phase really blew me away! Read more

Before doing serious work with these four analog noise reducers, I thought I should get to know them properly with some lab tests. Read more

Which reduces wideband RFI better: digital versus analog SIFT. Take a look at my experiment and judge for yourself. Read more

Can you remove multiple RFI sources at the same time with spatial filtering? Perhaps, but it’s not easy. Read more

If you set up noise antennas properly, any of these devices can work for you. That’s the essence of my QRM Eliminator Wrap-up. Read more
