Peter, I really enjoy your videos, they're informative but at the same time, I don't get the feeling that you made the video strictly to sell product. Even though I'm in the U.S. you've helped me out quite a bit (maybe it's time to open an outlet stateside, eh? 😉). I've said it before, and I'll say it again - "Thank You".
Wow! I did not expect the unit to work as well as it did! That's remarkable. I'm sure it would a session or two to learn how to use it well, but definitely worth considering. 73 from the USA!
Peter, thank you for this thoughtful review. For the now, at my home the noise floor is S5-7 - my focus is on locating and reducing RFI from inside. Your analogy of trying to dig out a signal from the noise background is the experience here. After looking to reduce the RFI, it may be that a tool like this will “step 2” - so glad this option exists. 73 KQ4IXD
Very nice video Peter, and a excellent unit that works fantastic although at the same price as 3 weeks shopping for us, I will pass. If there is a decent unit on the market for those of us with smaller pockets, I would love to see a video. 73.
I remember DSP noise reduction units from Radio Shack, here in the US, back in the 90's. I had a fellow amateur HF operator friend who worked a lot on noise reduction with his equipment. 73 de W2CH Ray
As usual Peter, great review. Your vids were a lifeline during lockdown and so glad you kept them going. You talk to us not down to us - great skill whilst trying to impart years of knowledge. Thank you. 73 de M0AZE Mike
Thanks for the review. Like most people my ability to copy signals is determined entirely by noise so that anything that could 'lift' a conversation above the noise is valuable. I've seen something similar to this in Audacityy (sound processing) software -- their noise reducing plugin seems to rely on noise never actually being purely white but having characteristics that allow it to be identified and so canceled. The equalization function is OK but a graphic equalizer might offer more (and they're really cheap these days). What does show promise is something I read about recently which used spatial separation of frequencies to give a synthetic stereo effect; it didn't actually remove noise but moved its components spatially so that you could pick up conversations much as you would at a noisy party (or standing near a waterfall). Anyway, great video as usual. (BTW -- You've got a mixing desk...have you tried plumbing your receiver through it?)
I use a wimo qrm eliminator quite pricey BUT does the job it suppose to do and being in an area with power lines pretty much above me this unit does help some what I wouldn't mind testing this out and comparing mine and that 1 👍 good video
This makes me wonder about implementing an old friend (from the days of *cassette tape* -- yes, I'm *THAT* old), _Dolby Noise Reduction,_ in ham radio. Or is the audio bandwidth of an SSB signal too narrow to make it possible/worthwhile?
It works well but It Is too much aggressive for my use. Furthermore highs are strongly affected as in the actual competitors, the highs loss Is one of the big problems of this devices. I use an old Ten Tec Omni7, working with RF gain, AGC, Bandwidth, volume and my brain I get a similar or Better result.
Thank you for this review. As you probably know, the G90 could use help with noise reduction, and your review has me seriously considering this unit for use with my G90. Would it be possible to stack the two, or are the sizes incompatible?
instead of having your mic try to pick up the speaker you should have piped the audio out straight into the recording software so we could hear it better.
Great review! Can the GNR1 get power from a standard HF PS running at the normal 13.8 volts? It looks like unit comes with a 12 volt PS but I would like to just use one PS or a battery in the field. Thanks!
You did not show us what the NR setting was on the Icom 7300 and you did not adjust the NR on the 7300. The Icom 7300 also has twin Pass Band Tuning which you did not compare. I find the NR on the Icom 7300 to be better than audio NR from an outboard unit. This video seemed to be made to sell the unit and to downplay what the Icom 7300 could really do.
@@watersstanton I would like to see a comparison done that was not biased, one where the Icom 7300 had its NR adjusted and the twin PBT used in conjunction with it, as you did with the NR1. Adding on the NR1 requires an additional patch coax plus additional wiring for a 12 volt supply. My 7300's NR is better than the BHI, MFJ and the West Mountain ClearSpeech noise reduction units. I have compared those units myself. Maybe either I got a better than average 7300 or you have one that isn't up to par. Mine also does not add the underwater sound. 73, AA4EZ P.S. Love your WWII aircraft pictures on your wall!
On my IC7100, in the menu system, you can adjust either the bass/treble tone controls OR the high/low bandpass filter, but not both. One or the other reverts to neutral default. PLUS, they are both buried deep into the menu structure which makes on the fly adjustments a non starter.
My 7100 has a decent noise reducing facility, but my CLRdsp provides a slightly clearer sound, and the controls make it MUCH more easily and readily accessible. I would like to hear about comparisons of the Xiegu unit with the CLRdsp.

Peter the difference is like night and day. I have never been impressed with the NR on my 7300 but that external device sounds great !

just purchased one online, look forward to testing on Aussie noise !
Wow, that device works really well! Very good review Peter! Cheers!
Lots of QRN and QRM here so I just ordered this. Thanks for the vid.

It sounds like a fancy analog audio expander/noise gate.

As it is an audio processor. Would be useful with SDR recordings? Enjoy your channel! 73.

Great review Peter, looks like I will have to buy one.
Great demonstration. Thanks.

How does this fair up against the NR and stuff on a DX101MP ?

AMAZING
How about this one ? ;-) ua-cam.com/video/pRs3m1jDysU/v-deo.html
How does a Wolfwave compare to this unit?
instead of having your mic try to pick up the speaker you should have piped the audio out straight into the recording software so we could hear it better.
What noise reduction units have you tested list Thank you
Great review! Can the GNR1 get power from a standard HF PS running at the normal 13.8 volts? It looks like unit comes with a 12 volt PS but I would like to just use one PS or a battery in the field. Thanks!
just got this unit, first glance, my icom 775dsp radio has a better dsp , but my ts 480hx is 100% better with the nr1.
Is there a possibility of damaging the noise reducer during radio frequency transmission? PU2-UBB
Noise reduction isn't one of Icom's strong suits that for sure.
Its works like the Dierking dubbel noth from £Germany I searh for a extern Noise Blanker for my Proff. Receivers tu 73,
By chance, have you reviewed the West Mountain CLRdsp version of this? Can you share thoughts on your comparison?
Sorry, I have not used this.
As usual the page for purchase hase disappear
What other audio dsp noise reducers have you used, such as the bhi or mfj, and how do they compare with the Xiegu?
I did a review on bhi model and MFJ coming up.
Same with the speaker :) Out Of Stock :)
Keep up....They are demo unit's
You did not show us what the NR setting was on the Icom 7300 and you did not adjust the NR on the 7300. The Icom 7300 also has twin Pass Band Tuning which you did not compare.

Quite simply the NR1 was more agile and better.
