Hello Darren. I think you don't understand fine the method for use it. The two antennas needed the same gain at time and after modify the phase. For this, decrease the gain of main antenna (usually have more gain than rx antennas used) and decrease a bit the rx antenna. You first need to find the point where all the noises (or the better s/n ratio) you have. At this point, the two antennas have the same gain. Then you can move the phase Potenciometer to kill the noise. You can see it in a video of my channel.
Great video and very well explain , i have the Ftdx-10 but i don't know where to connect the rca plug coming from the qrm eliminator to the back of my radio , if you have the time can you let me know where, thank you.
Impressive, but maybe you can explain something for me. The QRM was bad, but the QSO signal was still stronger, pusing the S-meter to 9. When you turned on the QRM Eliminator, the QRM went away, but the S-meter dropped to about S-2 on that strong signal. What caused the dramatic drop on the S-meter without any audible loss in signal strength?
Good evening from the Philippines, just wanna ask what kind of wire and size you used to connect to the PL259 connector and then you hanged it around the house?
Hello Darren N4VFR I hope you are feeling good I have a lot of line noise here lately yesterday it was 20 over 9 on HF what is weird it comes and goes if it's raining no noise the noise blinker is useless on this radio Yaesu FTDX101 MP the Icom IC 7610 Scott a lot better noise blinker ON it it will take out over 80% of the noise my icom ic 9700 it is got the best noise blinker on any radio I've ever owned on 2 meter SSB it will get rid of static crashes I was wanting to ask you about The QRM Eliminator I believe it will only handle 100 Watts I'm not for sure but you turned the The qrm Eliminator off can you run 200 Watts thank you Darren N4VFR 73
I bought 2 and one of them came with a missing knob. I offered to agree with a $5.00 refund. It would cost a whole lot more to ship a single knob or returning the product to China.
I have a different problem, I have a noise floor of s3-4 normally, but I get a broadband burst every 15 seconds with a 12-13 second duration. Totally overwhelms the receiver. I don't think that it can be phased out. Still, for ambient noise with a consistent noise level, it seems to be the ticket. Thanks for the video. 73, Al
Al, It will be hard to tune out the broadband burst. You might see if you can find the source of interference. At least check if you can find out if it's originating from your house.
I just bought it last week and still trying figuring out its pattern. Now my auxiliary antenna has some distance to my main antenna, cancelling the noise is a little tricky; I need to cancel out different noises for different phases. Sometimes when two noises came in with different phases, there is a trade off. I've discovered that putting Gain 2 at level 5 (middle), it can do the job most of the time by only adjusting phase knob. However, when auxiliary antenna cannot reap enough noise, Gain 2 need to be at level 10 (highest) while Gain 1 should reduced to some extent. All in all, when spare time comes, I'll try for put both of the antennas close to see the result. Literally, I guess using beam antenna as the main should benefit a lot from this toy.
Take a look at the FTDX10 Manual page 13. Under the Tuner Port, you may need to connect the GND to the outside shield of the RCA plug and the TX GND to the center conductor of the RCA plug. Take a look at this: forums.qrz.com/index.php?threads/connecting-a-qrm-eliminator-to-a-yaesu-817.551786/
How can I use this using a pw1 amplifier I've got four antennas completely filled on the back of the pw1 how would I rig this up to work with the pw1 and the Icom 7700? Thanks Mark
You would need to connect the QRM Eliminator between the PW1 and you Radio. As far as connections behind the QRM Eliminator, Aux Antenna is connect to the sensing antenna. The TRX goes to your HF Radio, and the Main Ant is connected to your PW1 Amplifier.
Ok the reason this is not working is because your rx antenna needs to receive the noise the same or louder than your HF antenna. If not, your rx antenna is not good enough. If you rx antenna can't get the qrn louder the your HF antenna, how do you expect to cancel the qrn. All you are doing is reducing the gain of the antennas, plus you can't test it while listening to a station! I have the mfj1026 and my rx antenna picks up everything.
This is only effective if there is truly a local noise. Local noise as in a property noise that can be locally targeted with the position of the aux antenna.
You should be using a MUCH shorter aux antenna. You will not get the full effect of that device when the auxiliary antenna is also receiving The wanted signal. The antenna should be a 3 ft piece of wire or shorter so that it only picks up The unwanted local noise and not the signal of the other transmissions you want to hear
@raysult This is only true when the noise its near to your station. The better option it's the same gain for the two antennas in general. If the noise its far from you, it's better a gain antenna in the exterior.
Thank you for the interesting video . I bought one yesterday. I use a yaesu ftdx 3000 . And also a acom 1010 amp . But the acom use also the tx ground connector. Do you have any idea that i could connect the xphase to a other connector in the yaesu ? Or using a rca splitter on the tx ground ? No idea of this could do any harm ? I dont want to destroy the apm 🙂 .... And the xphase dont work if you not connect the ptt ?
Use a RCA Y-adapter. I connect my TX Send from from my Icom IC7610. One end of the Y connection goes to the Amplifier and the other to my QRM eliminator.
Dear thanks. I appreciate your help . Is a standard RCA cable good? Like a yellow ( Video ? ) I don't understand much about these cables. Kind Regards on7cdh

Hello Captain Darren 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
Congratulations on the Super Yaesu 101MP. It's a beast of a Transceiver! Don't mark my words, but if the QRM Eliminator is turned off and bypassing the circuitry, I believe you can transmit 200Watts. Maybe first try 120 Watts and work your way up to 200 Watts. It does get complicated when you start adding antenna switches. I'm just thinking that your QRM Eliminator also needs to have a seperate antenna to sense the interference. First try using it with one transceiver and once you mastered the skill, put in another antenna switch on it. Good luck!
@@MONTY-YTNOM This is cut and paste from a QRM Eliminator PDF, "When transmitting through the QRM-Eliminator connect the PTT-Line from the back of your radio where normally your PA is connected. PTT is active when center pin is grounded. Do not connect to the PTT-key on your microphone! Max. power rating is 200W. if you want to use an amp, the QRM-Eliminator is to be connected between amp and exciter." I hope this helps.
On the back of your radio, you will need to connect a coax from your radio's tx/rx to the TRX of the QRM Eliminator. Keep in mind, you will need to have another antenna (Sensing Antenna) of almost equal receive strength in order to properly cancel out the RFI.
@@DarrenN4VFR on back of galaxy it has rca for rec.and rca for frequencycounter..when keying mic it has connectivity.could it connect to rca ppt.on eliminator??
@@charlessalard4636 Ohhhh okay. I don't think this will work for you because your transmit and receive are on two different ports. Typically, the TX/RX are on one coax port.
I took it out because my City Ordinance allows us to only have 1 antenna/aerial. I haven't made any progress to fight them yet. Been busy with family at my other QTH. I'm gonna try a loop antenna as a receive antenna and my Zero Five antenna for my transmitting antenna.
I got the same thing on my radio. It's called rfgain. I say this because ,you're killing the wanted signal along with the noise. Note s levels. Snake oil
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 
Common mistakes that people do and they THINK they reduce noise. See this part of the video ua-cam.com/video/__bvoUl7A8U/v-deo.html Here you think the noise is down, but you are actually attenuate BOTH the signal and the noise. The signal is already S9+ and when you switch on the eliminator, the signal drops to S2. However the noise also drops to very low levels. You think that you have the correct setting, but in fact all you did is attenuate the signal and the noise! If you try to recover a weak signal with this method, you can never do it! I do not say the x-phaser does not work at all, It is just not the correct setting in this part of the video.
I use the QRM eliminator to drop my noise floor about 3 S-units. I pretty much leave both knobs vertical. I keep it on and use my IC7610 on remote. It helps a little.
Thanx Cap'n D :-) I love the ham energy you have and I expect you deliver that focus and energy to be tuned in as necessary as a pilot. AS mention previously, I am in Mims FL (between Daytona and Melbourne - near Titusville) - wish I was closer I would want to visit you. Thanx for the clip re: QRM Eliminator - tho puzzling to me is I thought your noise problem from a few months ago which was truly awful, was cleaned up by the power company ? is this a different unidentified source? cheersw - and again love your video clips - well done and your entire setup challenges and directions you took were informative.

I agree that a shorter sense antenna would be desirable so it only picks up the local noise and use vertical polarization on the sense antenna.

Hello Darren N4VFR
I hope you are feeling good
I have a lot of line noise here lately
yesterday it was 20 over 9 on HF
what is weird it comes and goes if it's raining no noise
the noise blinker is useless on this radio Yaesu FTDX101 MP

on 2 meter SSB it will get rid of static crashes

I'm not for sure but you turned the The qrm Eliminator off can you run 200 Watts
thank you Darren N4VFR

8:00-9:00 mins, your received signal was reduced with the ambient level, signal%noise was unaffected, it's just an attenuator 💃🏼
Yeah, the signal is attenuated and his audio still was intelligible without much of the hash noise. Just like adjusting the RF gain.
Cool...Have power line everwe're around my house...👍like it...Thanks
Diversity tuning is brilliant, benefits of a dual VFO transceiver to do this in the radio itself. Tried this on the SDRplay Duo.
Do you have any references I could look at to learn about doing that? Thanks!

You have to adjust both Gain so they're almost the same signal level which in turn lowers your receive signal a little.
