[Lowfer] RF Noise Canceller

[Tom Brent]

Wishing everyone a Good New Year.

Hi Tom?..can you provide us with a link that will take us to the correct site?
I did a search for ?phase X? as you suggested, but the hits didn?t seem to
have anything to do with noise cancellation at radio frequencies.

Since my interest is mainly with MF, LF, and VLF, I?d be interested is seeing
your modifications as well.  Thanks!

Hi J.B. , there are many places on the web showing various designs.
I searched for hours looking for what I thought would be easy to build and work well.
In 1992 the S.E.M Eliminator was introduced and for awhile was popular. I think it's demise
were fakes and lack of knowledge on how to use it. Below is the link containing the schematic
that most closely matches my build.  However a key mod to this design is
the toroid used on the sense antenna input. Using a BN 73-202 core for LF and below.Turns ratio is 8:2.

Note that the ln914 protection diodes don't work well. I killed several J310's until I went
to TVS diodes. I might be able to supply my diagram if I can find it if you would like to see it.
