This is a topic that interests me. I have a wrinkle to add.
Qualifications: I am a generalist rag-chew HF phone operator / listener.
I'm not seeking rare DX nor exploring weak signals in general nor a
competitive operator.
I'm currently running K3(-s) with a DXE NCC-2 and a 2 x 6 remote

QRM eliminators can work surprisingy well at times and appear next to
useles at others. It's rarely the unit, rather the situation. All of
these similar units, of which the MFJ noise cancelling signal enhancer
is but one operate by combining two essentially identical signals, the

Hi Gernot.
I use an LZ1AQ double mag loop (rotateable) to null out as much hash as
possible. This feeds the RX Ant In input on the K3S. I also have an MFJ
Noise eliminator which is also inline, using the LZ1AQ as the main (RX)
antenna and

Diversity is not helpful as a QRM eliminator.
Antennas with steerable nulls can be helpful, small loop antennas have very
deep nulls but also require a high gain, low noise figure preamp and very
careful

I have the MFJ 1026, with the built in whip and it eliminated a local

Hi Alan,
The MFJ works very well as a noise eliminator

Hi Gernot.
I use an LZ1AQ double mag loop (rotateable) to n
it. Once/if I get the MFJ untit to work, I may then buy one of the
more expensive noise eliminators.

Hello all,
In a recent rush to eliminate urban noise I bought an QRM eliminator.
The working principle is to null out signals by shifting the phases of
two antennas (one main/tx and one rx). I can see the effect sometimes,
but it is not the holy grail for all types of QRM. I still don't get rid
