FTdx10 & IC-7300: Noise Blankers (Video #14 in this series)

My good friend Joel, KC4WZB, loaned me his brand new Yaesu FTdx10. When I say loaned, I mean he picked it up at Ham Radio Outlet and brought it straight to me, so I could unbox it and shoot a series of videos, exploring the capabilities of this latest offering from Yaesu.
This is the fourteenth video in a series of videos I will be producing to show the capabilities of the Yaesu FTdx10. In this video we look at the noise blanker for both the FTdx10 and the ICOM IC-7300.
A Noise Blanker is not the same as a Noise Reducer (aka Digital Noise Reduction). A Noise Blanker is designed to lock onto noise that manifests as repetitive pulses, such as power line noise or the noise generated by the motor in an automobile.
The Noise Blanker detects the noise amplitude and timing, and counters it with an equal amplitude copy of the noise at 180 degrees out of phase. This effectively cancels, or blanks out the noise through a process known as destructive interference. It’s the same concept used in noise-cancelling headphones, though the Noise Blankers in amateur radios predate noise-cancelling headphones by decades.

Thanks for such a great video series! I've been considering getting the FTDX10 for use as a base station, and based on your videos, I'm completely sold on it. I've always loved Yaesu radio (though I've had others). And I have my FT-891 for SOTA and other backpacking adventures. I love how the screen displays on the external monitor as well. It will look great on my Sony TV. Cheers and 73!

No radio is without flaws, but the FTdx10 gets it right in most of the right places. I can nitpick it, but the positives outweigh the negatives. I also use a FT-891 for SOTA. I recently built a light loadout pack around the LNR Precision MTR4B V2, but it is a compromise to be sure. The receiver in the FT-891 spoiled me for 3 years. Having 100W when needed is also quite nice. Thanks for checking in! 73, de N4HNH

The timing settings don’t always help. And when the NB can knock out the noise, it introduces distortion. The DSP noise blankers are just not as effective as the analog noise blankers of old. If you get your hands on a Yaesu FT-890, you will understand why I say that the DSP noise blankers are inferior. The FT-890 NB knocks out the noise without the need to adjust timing, and it doesn’t introduce audio distortion. It’s cheaper for the manufacturers to use the DSP for the noise blanker. They only need to write some code. The analog noise blanker requires discrete components and space in the radio to mount the components. While DSP can be wonderful, it isn’t great at everything. We are being fooled into thinking that the latest technology must always be the best. But that isn’t true in all aspects. The manufactures must love it that we are fooled by their “latest” technology marketing speak. It increases their profit margin at our expense. 73, de N4HNH

Hi James! A noise blanker doesn’t really help with static crashes. It deals with noise pulses, like the 50/60 Hertz “buzz” from a power line (usually resulting from loose or dirty hardware), or noise impulses from an automobile engine. The DSP noise blankers don’t tend to work as well as the analog noise blankers of old. But the analog noise blankers were prone to causing degradation of selectivity. I can say that, as far as DSP noise blankers go, the one in the FTdx10 is about as good as I have seen. Just don’t set it much above level 5. Use the lowest setting that will minimize the noise. With higher settings, distortion is introduced. I hope this helps. Thanks for your comment! 73, de N4HNH

The 3D has its pluses. If you use the default color setting, and set the Peak to a setting of 2, the voice inflections and CW pulses are easily visible. You can also see the amplitude of the previous few seconds of modulation as the spikes move toward the rear of the display (the time domain). And, finally, it just provides another option in case you want a different view for a change. 73, de N4HNH

Nice video. I was just looking at the manual to my own Yaesu radio and it says that the NB, “can significantly reduce noise caused by automotive ignition systems.” When using my radio on the base, like yours, my NB does not really do anything. One of these days I will have to try it in my car to see if the NB works well there or not. I do have lots of other filtering options however, so not much concern on my end.

@n4hnhradio 3 жыл бұрын

The noise blanker can handle short duration pulses. Mine can deal with power line noise up to a point. It will diminish it but not eliminate it unless the noise is below S3-4.. The power company came and fixed the loose hardware that caused the arcing. There was still 2-3 S-units of buzzing but the NB handled it. What a NB cannot usually handle is noise caused by wall warts, cheap LED bulbs, wireless phone chargers, plasma TVs, etc. A noise blanker can degrade selectivity, and in some cases, introduce distortion, so it is best to only use a NB until you can fix the source of the noise. 73, de N4HNH

A lot of folks don’t realize the yaesu ftdx3000 noise blanker is not a 1-100 level adjustment. It’s a group of 10 mixed algorithms with 10 variants each selected in a 1-100 fashion. The manual does a poor job at explaining this. You have to find your NB sweet spot and typically NBW (wide) mode works best. My sweet spot is at setting 40. Also I noted that it changes between ipo/amp1/amp2.

I have both, there are a couple of things I like better on the Icom, progressive tuning and the ability to hit the touch screen and pick how fine the tuning is or really zip across the band fast .... I like the 7300 waterfall better with averaging , I also like the fact you can turn it off and just use the meter display, imo this is super helpful. The tuner is slightly better in the icom, my antenna is questionable on 15 meters the icom will tune it the yaesu will not. I havent completely come to a conclusion on tx quality but I sense the icom is slightly cleaner after listening to my tx on remote sdr receivers ..... other than that I can tweak the ftdx-10 on weak signals slightly better than the 7300 , I have both radios on bose speakers which definitely help with sound . oh, and I like the dual tuning wheel ...just wish the buttons around it had better spacing

The noise is worse without attenuation. I don’t compare radio to radio according to their S-meter readings. S-meter calibration from manufacturer to manufacturer varies.

@@n4hnhradio It is correct but how much noise you hear with the signal of that ham with a slow agc. I'm not sure the question is correct as I use google transducer, slow AGC should make noise not persistent with such a strong signal. It would be different if you hear a weak signal with a strong 3 or 5 kcs apart. It is very true that the NB deform the signal if you raise it a lot, all of them do it until the old generation equipment. I do not believe that new technologies are worse than old, only that they are made to be useful when they are necessary. My best NB undoubtedly the 897 from yaesu but I have not had high-end equipment like new SDR Anan or Flex and much less 7851 or one like the one you have FT5000, it would be very good to see tests of the 5000 in those conditions.

The analog noise blankers, like in my FT-890 and FT-920, can be left enabled. I ran the FT-890 in my truck for 14 years. I have ignition noise pulses. The FT-890 completely eliminated the noise, with no distortion. The FT-891, in my same truck, cannot even eliminate the noise completely, but it also introduces distortion. I’m thinking about putting the FT-890 in my truck again. As a bonus, the antenna tuner in the FT-890 can tune my 10-meter hamstick on 12, 15, 17, and 20 meters. One antenna for 5 bands. I worked stations 3,500-4,000 miles away on 20 meters with a 10 meter ham stick. The FTdx5000 has a better NB than the FT-891 or the FTdx10, but not nearly as good as the FT-890. 73, de N4HNH

I have the dx10 and had the 7300 and the dx10 noise blanker without DSP is vastly better at reducing the intermittent powerline noise I have at my QTH, the noise blanker on the 7300 was only good for electric fences. The audio quality on the DX10 is far superior too, lower noise floor and the contour feature really makes a difference, it's a very sweet sounding radio, I can listen mostly to the DX10 without any DNR but on the 7300 I had NR on all the time because the audio was so harsh, with SDR you really need control over AGC or the audio can be quite harsh. If anyone has an SDR and SDR Console you'll know what I mean, having full control over AGC makes night and day difference to the harsh noisy audio of SDR's, don't believe me ? connect to any Kiwi SDR, if you can find a decent one with good antenna and where it's powered by linear power supply and has good antenna, go to the AGC settings and adjust it, you can really drop that harsh noisy audio and make it sound really sweet. But, I am really happy with the DX10, it's a big upgrade from the 7300 with much better audio, I always listen with headphones. The DX10 filters are also much better and much better able to cope with bleed over form strong close stations.

Does the DX-10 scope truly follow you out of band like the 7300 does after its latest firmware update and not just bury the tuning cursor to one side or the other with an indication arrow showing you which side you left the band. I know the 10 is a step above in many aspects but at this point is the upgrades worth the extra cash. Appreciate your thoughts.

I suppose because it is less expensive to let the DSP handle the noise blanker function. The analog noise blanker requires additional discrete components. And hams already gripe about the price of the radios today. They don’t realize that if the price of radios had kept up with inflation over the years, the $1200 radio from 1959 would cost over $12,000 today.

do you think the nb cleans up electrical him and other interference, but not background static?

@n4hnhradio 2 жыл бұрын

A noise blanker works against pulse type noise (Man-made noise - aka QRM). A noise blanker cannot mitigate atmospheric noise (QRN where N means Natural noise). Atmospheric noise can be minimized with IPO, attenuation, RF gain, and a DSP-based noise reduction algorithm (DNR). I've covered that in other videos. A noise blanker tracks noise pulses and detects the interval of time between them. Based upon the interval of time, it interrupts the signal at the point where each noise pulse occurs, preventing that portion of the signal from being passed through to the next stage of the receiver. This usually works well against 50 or 60 Hertz electrical power noise (from power lines) or against ignition noise from an automobile engine. A noise blanker is not effective against broadband noise. The FTdx5000MP includes a wide-mode noise blanker option that can work against noise pulses of longer duration, but there is a limit. Some newer transceivers, while not including a separate wide-mode noise blanker, allow us to adjust the noise blanker width and aggressiveness (rejection level) via their menu system. Such transceivers as the Yaesu FT-891, FT-991A, FTdx10, and FTdx101D or MP include that option. Note that a noise blanker adversely affects receiver selectivity and it can introduce distortion into received audio. A noise blanker should be considered as a "band-aid", to get you by until the source of the noise can be eliminated. 73, de N4HNH

@johnnybwrlr983 2 жыл бұрын

Got it. When I saw your video and you stated the nb wasn't too effective on these newer radios, I thought you were referring to elimination of what sounded like background static, not hum or generated pulses. But I cannot always discern static from generated noise.

@n4hnhradio 2 жыл бұрын

QRN (N for Natural noise) is more like white noise. It is constant. Power line buzz or engine noise creates distinct spikes that rise up out of the QRN. The spikes are easily noticeable on a waterfall. The noise blanker is never a perfect solution but I’m critical of the newer ones because they tend to introduce distortion in the received audio. The traditional noise blankers didn’t introduce distortion. They usually silenced the noise well but they degraded the selectivity of the receiver. You would hear splatter from a QSO 6kHz away but it wasn’t that the transmitters 6kHz away were actually splattering; it was the noise blanker allowing a wider portion of spectrum to pass through. 73, Doug

I can set the NB on my FTdx-10 to make it effective at removing the noise on 160M & 80M I have much of the time at my QTH. BUT, it creates a very harsh & ragged sound on the SSB signals that get through, even at the lowest settings. It is much worse that the IC-7100 I have, which is also effective at removing the noise. The DNF also creates this harshness. Because I have to use DSP to make the listening acceptable, I cannot recommend the FTdx10 for those in a similar situation. I really expected Yaesu to do a better job on the NB. It is a deal breaker for me & I will be selling mine & revert to the 7100. I'd keep the FTdx10, if I knew Yaesu would fix this, but my experience tells me that most radio Mfgs do not fix NB & NR complaints.

Digital noise blankers are not as good as the analog noise blankers in some vintage radios. The Yaesu FT-890 has the best noise blanker I have ever used. Couple it with an external DSP, like a Timewave DSP 59+, and you have a winning combination. The noise blanker in the FTDx10 works okay as long as you keep the level set at 3 or less, and definitely don’t exceed a level of 5. But most digital noise blankers degrade receive audio quality to some extent. I use ATT, IPO, and RF Gain first, to minimize the noise in the front end of the receiver, before I even begin to tackle it with DSP. In my case, the NB in the FTdx10 has done well at dealing with local power line noise. It even did well at tackling some nasty noise from a computer power supply. Noise blankers, even great ones, do tend to degrade selectivity in a receiver. So, I use them as a stop-gap measure to get by until I can eliminate the source of the noise. Thankfully my local power company is good about responding to my noise complaints and tightening or replacing loose/old hardware. As far as the DNF in the FTdx10, its affect on receive audio is unacceptable. I only use it when absolutely necessary. I’m sorry the positives of the FTdx10 are not enough to make up for the negatives in your case. There is definitely no one perfect radio. The closest to perfect I have ever experienced is the FTdx5000MP. 73, de N4HNH

Rob Sherwood on the 10: "As with many noise blankers, it distorts the signal if turned up very high." I'll have to go back to see if Rob has commented on NB distortion on other rigs. Since the DSP is a separate group in the S/W, maybe Yaesu will improve it. Since I was using a IC-7100 before the 10, it was the standard for comparison.

Wide mode in the FTdx5000 definitely helps. I published a video about it. But, admittedly, wide mode level and width is adjustable in the 5000.

I sure wish Yaesu would get away from that FUGLY blue color on the metering. Should be green below S9 and red above S9.

It’s firmware. Go to Yaesu.com and send them a request. The engineers are in Japan. You can tell the Americans all you want but that won’t change anything. The product managers are in Japan. 73, de N4HNH

This is why I won’t buy one. On sale for $1,400. And the noise blankets on these SDR radios suck. I’ll keep my MarK V.

The Mark V is a fine transceiver. I’m thankful that my FTdx5000MP has both a traditional noise blanker and a wide version. Sometimes the wide-mode version is needed, especially against noise from a digital source. But, the Digital Noise Reduction in the FTdx10 is very often all I need. It has DNR that is on par with the DNR in the FTdx5000MP, which is the best I’ve experienced in any transceiver from the major manufacturers. The down-conversion dual-superheterodyne receiver front-end, in combination with the FPGA stage, gives the FTdx10 the edge over just about any transceiver on the market, with the exception of the FTdx101D or FTdx101MP. But, for my style of operating, I still favor the FTdx5000MP. 73, de N4HNH

Wow...the NB is useless and your sample really wasnt that heavy at all. Thats very disappointing and Is a deal killer for me in my neighborhood. My ftdx3000 does a good job has narrow and wide NB and 100 different algorithms and doesn’t screw much with RX audio. Takes S6 in power line noise and dsl digital noise to S1. It seems these new designs are really cheapened. Come to think of it....even the ic-7300 NB does a better NB job than the ftdx10. Also doesn’t it seem the ftdx3000 was an underrated radio? In my opinion it has been. it’s all in the setup and driver operator as you demo all the time here in your videos. If there’s anything you teach here is how to truly use the common set of tools common to most every radio operators ignore to really dial in that RX signal. For yaesu it’s the contour I help others understand that makes a huge difference.

You can adjust the noise blanker width and depth. The FTdx3000D uses the same DSP chip as the FTdx5000. 73, de N4HNH

Icom ic 7300 NB is much better...

No one Noise Blanker handles every type of noise. And I haven’t found one DSP-based NB that beats the one in my Yaesu FT-890, circa 1991. IC-7300 cannot handle every type of noise and neither can FTdx10. Any Noise Blanker is only a temporary solution until you can stop the noise at its source.
