QRM Eliminator / RF Noise Canceller 

I also own the same QRM eliminator. This is the best demonstration of its use and effect on RU-vid! Thank you.

Congratulations for the video! Can you advise PTT cable details ? Thanks

It would have been nice to hear the system with the noisy lamp on and off.

Should this be a standard feature in modern HF transcievers given the issues many hams now have with RFI which only seem to be getting worse as more and more noise generating gadgets are installed all over the place.

I got one similar unit from MFJ, it worked great to eliminate noise from nearby commercial lightings while I work 6m, and it got auto Tx sensing to bypass the unit without additional wiring, but on this particular channel I need to add a 1.25x accelerator as well...

Thanks for this presentation. I have ordered one and hope it will help me to drop down and eliminate the noises here for better SW reception.

Excellent video. Thanks for sharing. I could use something like this on my set up here, especially on the AM band.

Works well! Thanks for the video!

I just borrowed one of these to test. My main antenna is a 40 m long EF, about 10 m up. I first tried my 144/440 antenna as aux, because I had read that it was a reasonable choice. It was not good, because the box didn't register any noise at all. I then ran a 10 m wire out the window. This picked up more noise on aux. I was able to clearly reduce the overall noise (using SDR Console to view), but readability did not increase. I was listening to an AM transmission on 80 m. After some experimenting, I clearly had the noise down by a few S, but also the clarity of the AM transmission. I will try a better antenna, and update my comments.

Interesting presentation, Paul. Clearly this device eliminated the QRN source, and probably could assist in reducing a local pesky QRN issue. So for the money, it could be worth a try. The problem is when there are multiple sources, like there are in urban areas. In those situations, we are pretty much stuck. Thank you for posting this and 73! de WX0V

I use the MFJ 1026, it does the same thing and works very well!

Have you tried adding some extra coax leading up to your noise antenna so the phase setting isn't pushed to the limit? Maybe it could have been matched even better...

Obrigado

The reason the current consumption was lower I am guessing is that in transmit (by-pass mode), I am guessing you are having to energise a relay coil or two.

thank you

Nice review. Thanks.

Muito obrigado

Very well explained to the World. Thx for sharing this with us. 73's de Your Friend Uncle Günter

Congratulations on the video. Your device has 2 gain and one phase knobs. Others have 2 phase knobs and a gain knob. Can you tell what the difference is? Thanks

Thank you for the video, i ve just bought mine, have a nice day from FRANCE

I was wish to see it connected by ptt on a transmitter would be nice to show us how the ptt connected to example a 11 meter cb radio like jackson 1 or superstar

Where would you place the SWR meter in this case ? Between the TX and QRM Eliminator OR between QRM Eliminator and Main Antenna ?

i would like to see a video where this one compares to the QRM-Eliminator model "X-Phase" made by RA0SMS. which one will performs better ? i wonder

HEY GOOD DEMONSTARATION,,, DID YOU MAKE ANY QSO WITH IT ?

Does this go before or after the antenna tuner? I have read both...

Thanks for the video i really need something like that

QRN. It's QRN. QRM is man made interference, not electrical noise. A station operating one kHz away from you is QRM. Atmospherice noise, lightning static, wind/rain/snow static, electrical impulse noise from appliances, ionospheric noise is all QRN.

Good presentation but what if you do not know what the source of the noise is?

top Video thanks

How to bypass it for QSK transmitting?

Nice

Can you talk an transmit while receiving.?? Never see anyone talking while it's on??

how to connect to ptt to ic-706mk2??

"If you have the pedal." What pedal?

I purchased one of these hooked it to my rig expert and on 40 meters when I turn the unit on the SWR jumps from 1.04 to 3.5 so it is unusable for me. Have you checked your SWR with the unit on? Both antennas are 1.04 or better stand alone.

I bought the WIMO version of this. Useless. It did nothing to get rid of the QRM. It did get rid of wanted signals, which is awful. Main antenna is Steppir DB11. Aux antenna is a small telescopic whip with PL259 connector.

Hi Paul, nice device. Did you try this with 100W Power of your ICOM transceiver already? Because this is the big problem with my 7300. Tnx for any hint... 73 by Martin DG4BAD

Is it QRN or QRM? QRM is interference from adjuecent frequency and QRN is noise according to radio lessons I have learned. 73

Thank you for telling me about this product in our QSO on Thursday 14th September 2023, as promised I found the video & watched all of it. All looks good 73 de M3TZX

so you don't need to use the PTT then? will the radio not be damaged if you use without it?

Hello I got a Yaesu FTDX 101 MP QRM Eliminator is turned off can you transmit 200 watts ON it another problem I would have with The qrm Eliminator all my HF antennas come in the House to a big 2K a Ten Tec 229B manual Antenna tuner on the back of my Big Ten Tec 229B antenna tuner I got a coax jumper running to antenna switch box for two different Radios Yaesu FTDX 101 MP ICOM IC 7610 thank you 73

Przetestowałem to i działa ale musiałem wymienić płytkę ztylu na sztywną alu.

So you can not transmit through this with cb, only hf radio can transmit through this?

what is the transformer at the bottom of the primary rx antenna?

How do you hook this up if you're using ladder line?

thanks my friend another good video 73 from kb2uew

Hello, I have this device, unfortunately without instructions. Am CB radio operator. Can you please tell me what I have to connect where and how I set up the device. Best of all, step by step. I thank you in advance. With kind regards 

All you demonstrated was that it does what you describe in that situation. Placement near the noise source is the key and is the problem in the real world. The signal you use is not nor is it similar to a voice transmitted thru a radio. Put together a real life scenario and record and post video.

Cool 👍

Seems all this did was magnify the qrm noise.

Lol...quelle horreur !

Lol...c est de la merde

The best way to get rid of QRM is to eliminate the annoying Ham Operator.
