FANTASTIC  Time owned: 0 to 3 months

If you think you're gonna plug this in and it will magically make all your QRM/N problems go away, you are sadly mistaken.
Read the book however and it can virtually eliminate a noise source. Mine almost completely removes the S9+20dB plasma TV buzz from my neighbour's new one eyed monster. It makes the difference between running the noise blanker flat out or having it tick over, thereby helping preserve the dynamic range of my IC-7700.

It's NOT a noise filter, it's a phasing unit. You need the interference to be received on both your main aerial and a noise aerial. The whip may do but probably won't. Put up a wire aerial for noise but that's all in the book.

Final advice: Don't expect it to be something it is not. It does EXACTLY what it says in the instructions. IF IT DOESN'T WORK FOR YOU, YOU ARE DOING SOMETHING WRONG. READ THE BOOK !

Excellent device!  Time owned: more than 12 months
Unit works very, well, I was able to completely remove noise and hear weak buried signals! No more listening fatigue, all gone!
Spectacular results!
Workmanship quality on mine is excellent.
If you suffer from local interference you need one of these. Once set up properly, with a good auxiliary antenna , the unit shines!!
This type of circuitry should come as standard on high end HF transceivers. Does a FAR better job of noise reduction than ANY fancy IF noise DSP reduction ! And that's a FACT! True, you try it! You will see...
Thanks MFJ, for a fine product at a great price, it has saved the 40 and 80 meter bands for me!!
Cheers, Les VK3TEX.

Proper antennas for MFJ-1026  Time owned: more than 12 months
Even for non-local noise it works. The key is having a second receive antenna that also "hears" the noise. I agree, toss the little whip or better yet buy the unit sans whip (MFJ 1025). The noise does not need to be as strong, just audible.

OUTSTANDING!!!  Time owned: 0 to 3 months
Wow! My MFJ-1026 is amazing. It took me just two evening fiddling the knobs to understand how to use it. Also read the manual… IT WORKS!!!.
I have always had high noise levels from the low bands up to 20 meters. I run my radios from large batteries. One day while using 80 meters with a noise level of S8 (which is normal for me) we had a power outage which my noise level dropped down to S1. This made me realise that S9 was not normal so I bought a MFJ-1026. I can now drop my noise level on 80 meters to an S3, not quite an S1 but I’m still happy with that result. But on 40 meters with an S8 noise level, most of the time I can maintain S0-S1 which at first I thought it was just detuning the front end of my radio until tuning around and hearing S9+20db signals and also hearing week station across the whole band.
The supplied auxiliary whip antenna needs to go! I am using about 30 meters of standard electrical wire running along the length of my wooden fence pushed in to the auxiliary SO239 socket.
If you can’t tune out that noise, read the manual again and again… and if that still doesn’t do the job, then the noise is not local and probably everyone on the band is hearing that same noise.

I’m going to buy another one of these units and put it away as backup.

Better than first thought!  Time owned: 6 to 12 months
It works quite well on 40m and the lower bands, getting rid of the dreadful plasma TV QRM and various neighbours switch mode phone chargers.

I've still to get it to work properly on 20m.

All-in-all, most of the problems I've had have been from operator error. :(

Does the Job, works fine  Time owned: 0 to 3 months
I have the MFJ 1025, I obtained it due to a new TV in the house which was not my doing. Yes it is Plasma, it takes out most signals and puts out noise across the bands. I had to do something, from the reviews it looked like this product would do the trick. I would say that it has taken out about 95% of the noise and has made my life enjoyable once again on HF. If you are thinking of getting one make sure you do the reading and understand how it works. It takes a while to adjust out the interference. I use it with my MFJ 9040 qrp rig and the IC718.

Good product which may help your interference issues  Time owned: 0 to 3 months
When using this product there a lot of variables to consider, the type of interference being one. My intended use was primarily to combat sporadic power line interference that at times would overload my Icom pro with 10 db over S9 broadband signals. Chances are it will not completely eliminate your problem but in most cases certainly help minimize it. Auxiliary antenna gain is most important in reference to the main signal as the instructions specify. I experienced reductions of 3 to 4 "S" units when the 1026 was properly adjusted and the received auxiliary gain was sufficient. All tuning was done using an external 80 meter dipole (as the aux antenna) for interference reduction. While this was not as much as I had hoped, it did make my specific situation tolerable and the device a worthy buy.

Great funregainer  Time owned: more than 12 months
First off, mine is a 1025 model. After experimenting a bit with different "auxiliary" antenna's I came up with what I call a diplane. Actually a vertical dipole of about two times 2.75 meters with one end about a meter into the ground.

I have a strong local noise source which I can't DF so far. Specifically 40 meters was unusable. The "diplane" picks up the noise pretty strong on most bands so it's suitable for use with this superb MFJ product.

One has to get used to the controls on the unit but once you do it is not hard to eliminate the noise completely. For example, on 40 meters my S9++ noise disappears completely! All that is left is the normal (atmospheric) noise level of S3 to S4 and stations are R5 readable where they weren't even audible before.

Since my AUX antenna is very close to the rest of my antenna's, I added an extra relay to ground the AUX input when transmitting. I removed the lightbulb as well. This simple modification protects the AUX input circuitry.
If you need pictures, send me an email.

Reading the reviews here on eHam, I noticed some remarks about Ameritron/MFJ's QC. While I don't doubt there may be or have been issues, I have opened up and checked out several of their products and none of them had loose screws, cold solderjoints or anything else bad. Maybe, just maybe their QC is better on exported units.

Now back on track: This unit has brought back the joy in HAM-radio for me. Not only a keeper but also a unit I would highly recommend to anyone having this kind of local noise issues.

I even managed to almost kill a fairly local station on 17 meters. Went down from S9+35 to noise level....

Solved a serious problem for me  Time owned: 0 to 3 months
Purchased from DX Engineering (great service) and installed same day it arrived. Has now made useable 80M and 40M where my local noise was so severe it limited my use of these bands.

Simple to setup and use, it makes me smile when the noise just disappears and I can hear things that were previously impossible due to 9+ noise.

If you have a serious noise issue this maybe a suitable solution for you.

Does the job  Time owned: 0 to 3 months
I bought this through DXEngineering, to resolve some interference issues I have been getting from a neighbours battery charger. Firstly, if you want to instal the telescopic whip don't try to fit it with the top cover on, you will strip the threads. Take the cover off, fit the antenna and then put the cover back on - typical MFJ engineering...the hole on the top of the cabinet does not line up properly. Even after fitting the whip and replacing the cover, it sits very tightly against the edge of the hole in the cover.

Don't use the whip antenna unless the interference you are getting is right in your shack, or very close by in your house. It is useless for anything else. You need a really good antenna outside to really make this unit work well - the pickup antenna needs to be hearing the interference as good as your main antenna, or as close to it as possible.

With a bit of tweaking, and trying different noise antennas, I got it to work reasonably well - it knocked S 9+ noise down to S 4. There is a little room for improvement with my setup, so I plan on improving my noise antenna, to make it even more effective.
