RM Noise - While RM Noise is very good, and it has been mentioned by many people in the comments here, RM Noise is Windows only, requires a computer and requires an account to be setup. Also it appears an internet connection is required for log in and reliant upon a server. The product shown in this video is HARDWARE, no computer required. It's like saying to use "HamSphere" instead of a real radio to make contacts!
@@TechMindsOfficial that comparisson with hamsphere is unreal... And...internet comection....maybe 90 per cent of hams hace It....and a PC....maybe 85 per cent hace one........or maybe It am wrong. Who knows. But hey.... You are on a business i undertand you are doing marketing. And... By the Way a PC is also hardware, but... Hey.... This is a hardware that brings you the possibility to usé hundreds of software. If anyone want to usé a hardware dsp just do It, sure there is a cuote of the market. But is also real that 80 to 85 per cent of ham radio con have the same o better results free, al least today.
30 years ago I used a stand-alone DSP filter which had the facilities of this box but it also had the clever feature of putting in a narrow notch filter if it heard a continous whistle. It would automatically determine the frequency of the whistle and tune the notch accordingly. It could even cope with having multiple whistles at different frequencies. I can't see why, with modern technology, this can't be done now.
I bought this a month ago. I do not have any older radios- yet. I did add to my G90 and there is a noticeable reduction in noise. I found it is quicker to use than the G90's small buttons/menus. Of course it just made an inexpensive radio more costly, but hey I'll find another use for it. Now to go find an older unit to test on. 73.
Thanks for your great product reviews. I would not be put off using a DSP together with on a modern radio. I use a BHI and equaliser, with a 101mp. Using all the bells and whistles on the 101 and the noise reduction gives superb audio quality and is a pleasure to listen to for long periods. If you add a cheap second hand Bose docking station as your speaker you get hifi quality ham radio sound.
My President Lincoln II would be a candidate to test this I believe. The inbuilt NR predates the amazing NR now available as that used by the Radioddity QT40 and QT80. Very nice demo, thank you.
Still got my Datong FL2 from 40 years ago. Needed coaxing back to life (broken pin on RCA skt from wear and tear).Also soldered power lead direct to pcb as did not trust the 3.5 mil power jack. Not DSP but does everything else. G4BTI.
When radios start implementing some machine learning based filtering of audio noise... That should be possible with good results IMO and what's more important models could be updated online or via usb etc (and better radios could have ability to learn / update their local models based on user feedback).
It sounds quite effective. The noise reduction in particular sounded really good. The upper and lower filter skirt adjustment seemed to work well but, in real world use an auto notch and/or an adjustable manual notch filter would be a must for me in addition. For my fat fingers the 3 controls look like they are too close together to be comfortable to use. It looks like it has been designed to be used by a 10percintile female and not your average fat fingered bloke. It takes a lot to beat a Datong FL3 even at 40years old and I'm not convinced that this gets there yet. I have just bought an IC718 without the DSP filter board and I'm looking for an audio filter bi=ut this isn't it. I know where there is a FL3 going for a good price and I'll probably go for that even though I have a BHI here that I'm not very impressed with.
You have such a great radio voice, do you work for Broadcasting for a living? If not, you totally should. At least as a voice actor, reading instructions etc.
Thanks for a great, comprehensive review. As an 'old timer', the performance of this device amazes me.. It would be the perfect companion for my old TS140s, but, unfortunately, although more than reasonable, the price tag puts it out of my reach😢. Thank you.. 73..John..G4EIJ
A bit spendy at $215 USD for use with a single old radio - BHI similarly priced. If I had stable of older non-DNR radios like my Kenwood TS-440, then perhaps I could see the value. While some are tempted to pair with a Xiegu G90, it would be less expensive to just purchase a Yaesu FT-891. More rugged radio with better DNR than the Xiegu device plus 80 extra watts of transmit.
I still have my Dual DSP JPS NIR-12 from 30 years ago and it does the exact same plus different noise reduction methods and auto notch. It is technically almost unused because most of my receivers offer these features built-in. If they would have combined it with a galvanic isolation (transformers or optocouplers) for audio and a PTT relay and had included a USB audio interface and a USB to serial interface for CAT control, this box would probably sell like hot cookies, but offering only one fixed audio algorithm plus the low and high cut is a bit of a joke for such a big heavy case. It is really just useful for a tiny percentage of users with very old receivers/transceivers. While saying this, I think I just got an idea what I will add to my old DSP box ... a USB audio interface and a galvanic isolation, because there is some space inside for another homemade PCB. Anyway thanks for the introduction.
How does quickly does it stabilise post TX? This seems to be the issue with the BHI noise filters in that they take far too long to go back to their setting after you transmit? Although very good if you are just listening
It seems good. I did see the nr pushed up to 2oclock without harsh or watery sound which seems good. Ive got the old radio shack junk, bhi which is good for knocking the noise down, timewave 599 and a spare with barely decent nr but really great hi and low cut with frequency display for cut. Ptt cutout if needed. They aint cheap. Got the mfj with not so good nr and similar controls for lo hi cut. Its advantagous to set hi cut around 2400 to 2600. The problem with mfj and this one is you have to do it by ear. I put marks on my mfj but dont use it anymore since getting the timewave. Id like to try one of these for the nr. Nr is useless on my 590 but im in a quiet location for hi bands. 40 and 80 always noisy. 73
Long time ago there was a Kenwood DSP-100 to go with TS-850, which basically does the same tricks (at USD$800 or so). When IF DSP came out, these AF DSPs are out of market.
It seems nice to have for an old ft-857d or something, and i use a bhi speaker with my anytone 4m radio with good effect, but this seems to be selling for about teice as much as i would be prepared to pay for it. Can get s very decent radio for that money!
At this point, why not just buy a more expensive radio with these functions build-in? All this is build into my yeasu radios and not need for another box on the bench...
Xiegu has some excellent technology. They need to combine this with their top notch antenna tuner and incorporate them into a full size rig, with a big screen, to compete with units like the ftdx10 or Icom 7300. Currently, by the time you assemble all of their current components, you could buy a Yaesu or Icom for less money in a single unit.
Just a question. Wouldn't a Graphic Equaliser do the same job. Some of them had Scrath and Rumble filters as well. All though it wouldn't have an amplier but some did. I used to use one on an old valve receiver from ww2 and the Graphic Equiliser worked well but that was in the 1970,s. So not sure about modern interferrnce. George
I believe you failed to mention that this is a bi channel mono deviceso if filtering a stereo input then 2 units would be needed. So in fact a good studio compresser/ limiter / gate/expander and an eq would serve the same function. Or a variable filter array?
Hi Matt, do really appreciate your videos, however the latset videos has not beeing that good in the editing. I guess you are a little bit hefty when editing the sound layover where you miss some timeframes in the beginning of most of the sentences. It has become more an more obvious lately. Could be good to know for the future. You are obvius one of the most professionals in HAM radio research and do really like your videos. Hang in there.
@@VA3HDL its a game changer and it seems like very few people use it. none of the guys on my local net want to even try it out. old guys gonna be old guys i guess lol.
I don't get how they can put a DSP circuit in a box and then not offer any kind of notch filter functionality, which likely is even already on board. That looks as tempting as a Chinese copy of a Swiss army knife with only 2 blades/tools.
Zygote needs to take their g90 case and make a 6 MM 70 cm 20 watt transmit power all mode and all their other little absolutely wonderful antenna trimmer and noise cancellation that they have on their g90 and by using the same size case you could literally Bolt the two together and have two separate radios therefore being able to monitor HF and VHF UHF very easily

Do you happen to recall the manufacturer or model? Thank you.
Probably MFJ 784B
I press the BC on my TS-890 and that does exactly what you describe. :)
@@jasonprivately1764 Yes, it was a Timewave DSP-9. Details still available on their website.

It's about time they brought this out looking good
I still like my Timewave DSP599ZX for use with my old pre DSP radios.
And the SOTA Beams DSP unit with the FT-817.
This looks nice but is too pricey.
I purchased this unit to use with my Kenwood TS-450S. So far it has provided decent improvement, especially on noisy 40m late night SSB.
@@rcbaumannjr how much did you pay please
I use the BHI NES-10-2 Mk4 with a Xiegu G90 and it works fine. DNR and amplified speaker all in one.
Spot On. Well designed, objective testing, concisely presented. They ought to pay you for doing this.
Sounds nearly as good as the noise reduction on my SunSDR :-)
My President Lincoln II would be a candidate to test this I believe. The inbuilt NR predates the amazing NR now available as that used by the Radioddity QT40 and QT80. Very nice demo, thank you.
I make homebrew radio gear and that looks perfect for cleaning up audio.
Looks pretty good
Just another thought. It we good to see it in action against a Graphic equaliser. Even better against a 12vdc car one amplifier built in. George

G4BTI.
Check how it handles when someone is tuning, how it cuts out that squeal - the 'auto-notch' feature on the Icom-7300 handles it perfectly.
Interesting - I would liked to hear it used receiving a CW signal..
Me too.
I bought one of the Chinese QRM Eliminator X Phase and I find it really great.
deskhpSDR software has insanely good noise reduction built in. set to trained NR2 and its dead silent makes 80m sound like a cell phone call.

Great video. How would this work with a Kenwood R-1000?
Bought one of these and the matching speaker for my AR7030 and found no benefit bit of a waste of money and its not cheap
Very interesting
Seems like my Xiegu G106 would benefit from this.
Great video would this work on a CB radio?
yes
They should be connected to Politicians Mike's to cancel
their noise. 😮
Yeah starmer blanker
So I have a old JRC 525 in a very noisey QRM area.
Will this kill that noise?

no spacial audio.
totally useless.
