- A quick overview of the SOTABeams Wolfwave audio processor demoing the features and controls. More information can be found at www.wolfwave.co.uk.
Note that the audio codecs used in recording and presenting this video may not do the Wolfwave justice and that some of the features sound better using headphones.
The Wolfwave is available now from www.sotabeams.co.uk.
Nice. Love the way the information is presented with an fft plot there. Helps you clearly see where your interference lies and how to chop it out of the mix.
Mine arrived a couple of days ago, played with it on the local 2m radio net last night and it did may a big difference in my opinion. will try HF over the easter weekend now that I have seen from the video all the other functions
Wow. Coolest and most practically usable filter(s!) I've ever seen. Since Novice days back in 1977, lol. UK innovation continues to impress.
More motivation to regain my expired license.
And this presentation captured my full attention start to finish. Perfectly organised and executed.
I feel like demand will be very affected by this video. Hope production keeps pace.
Adding to my urgency to get back to studying before these disappear.
I feel like no ham would ever part with one of these magical boxes.
While it seems natural that Hogwarts has likely been cultivating electronics engineers since the invention of wire.

Thanks for creating and posting this video.
72/73 Cheers
I like this. Thanks Mike. Another informative video.
I am so close to being convinced to order one of these. Seems like it would shoot my FT-818 up into the KX3 category of performance. I already have the Collins filter installed well as the speech compressor, as well as the upgraded speaker. I run a BHI DSP speaker along side my rig, and this seems good, but after seeing this little gem I believe this may be just what the Dr. ordered. I love small gadgets.
Richard Macleery It really does an amazing job and very handy to be able to use it different radios too. The slight audio processing delay can make sending CW a little tricky at higher speeds but SOTABeams are working on this and have already beta tested a way to improve that. I have an external keyer with side tone so not an issue for me. For SSB (and AM for SWLs) it’s hard to see how you could make it better. It does a remarkably good job.
I ordered mine and they upgraded me to sign upon delivery. Grrrr!!! I had to go to the Post Office to pick it up. I got it home and waited till the dear wife went to bed and hooked it up. Works great!!! It can filter out all adjacent signals and isolate a signal down to Hz level. I plugged it into my LNR Mountian Topper 3B and had to take the headphones out so I wouldn't tear everything apart jumping up and down with joy!!! Thank you Sir as this video convinced me to purchase the product. 73!!!
nice feature packed portable dsp - 73 de HB9GNK and KB9GNK
As nice as this looks for CW, it looks more appealing to me for use on SSB. Every radio manufacturer should be bidding to incorporate this into there QRP radios. Seriously this little device looks like it turns an FT-818 into an FTDX3000.
Really good review, It seems like a very powerful unit. I did laugh at the solitary packing peanut though :)
Dean Godden He he he, just to be absolutely clear, the box does come fully packed with foam noodles...I pre-emptied it to speed up the unboxing. In fact, the Wolfwave was double bagged and double boxed so I really can’t fault how well protected it is in transit.
Michael Sansom I expected as much it was just the irreverent way you picked it up and launched it that made me laugh.
WoW amazing little box, thank you for the review. Greetings from Guatemala 🇬🇹 73 de Juan TG9AJR
Oooh noice indeed!
Hi Michael
Great demo of a very interesting product. I am considering getting a BHI noise cancelling unit as the QRM at my QTH is quite high. Obviously the Wolfwave offers a lot more functionality but how well do you feel the noise reduction works.
Regards
2E0WSF
stephen fine Ping me an email (my details are on QRZ) and I will try recording you some examples of the noise reduction. Let me know what sort of noise/interference you get so I can try to simulate that.
Habrá que probarlo!!!, parece muy interesante

qrp cw Me gusta el hecho de que puedo adjuntarlo a diferentes radios.
top notch review....de ne7ts
I wonder what is the advantage of this device vs the modern transceivers internal DSP filters?
Could you share your experience based on CW?
Thanks,
73's, Patrick - ON4KNP
I am thinking about decission to order an WOLFWAVE. But I am mostly working only in CW . The question I have before ordering is as follows : If I have connect the WOLFWAVE to the Transceiver … what happen about the 60 ms latency with the TX sidetone if transmitting and I hear my own CW (sidetone) through the WOLFWAVE if the WOLFWAVE is in processing-mode and not in Bypass-mode ??? Could it be that I hear my TX CW sidetone with detectable latency … which would make every CW Operator very confuse … ! Has anybody tested this and can report CW operation expiriences … ??? Thanks & 73. / HB9JOI
With the first firmware release I could detect the latency but it was not a problem at slower sending speeds. SOTABeams experimented with methods to overcome this and may have reduced the delay. I will need to measure it again to see if it's problematic when sending.
I used to have a Timewave DSP-59+ and it has a PTT INput, when keyed it changes the filter algorithm so no delay and makes the narrow filter wide. Otherwise I could not hear my sidetone with filter narrow and not exactly on my sidetone freq, which happened a lot in contests. Keyed it via optocoupler in my TT Argo 556 and also the amp key line in my TS-450S. how will it work with this filter? I am getting one next week.
Why is this not implemented as an audio plug-in for audio pipelines?
Hi there, could you add a section that shows Morse Decode? Stephen G7VFY
Hi. Is this device good also for SWL and AM? I am SW listener.
I actually used it more on my short wave receivers than I do on my Ham radios. It gives a high level of flexibility in filtering on basic receivers.
Hi Michael can you please tell me how you have the wolfwave set up for ssb voice as i just got one but not getting the same results as you ?
MØNXF As a starting point I opened the filters up on the radio as wide as they would go then set the centre frequency of the Wolfwave to 1500Hz and the bandwidth to 3000Hz (that’s wider than normal SSB filters so can sound great. When I get co-channel interference I long press the Multi Use button to select high or low and try removing just the upper or lower frequencies where the interference is present. You can just change the width but I feel it removes ‘good’ audio along with the bad.
@@g0pot Thank you very much for your help will try that later 73 de MØNXF Bill
@@M0NXF Feel free to contact us for tips and advice.
Hi @@g3cwi_Radio_Adventures thank you did a little demo at Cornish radio amateur club intermediate training on Saturday we have some very good cw guys one of them is a club trainer he said the cw regen sounded a bit like it was clipping the audio so need to play with the settings a bit to get used to it apart from that everyone was impressed it can only get better as i get used to the set up . The club has asked me to demo it at a club night and i have put a link to the video & sotsbeams on the club facebook group .
Higher volume on the video would have made it more enjoyable
why no demonstration of different levels of noise reduction?
amlite I have created a very short video showing the noise reduction for another Ham which I can share with you. It’s not a feature I use a lot on radios as I don’t like it’s effect so I’m not so confident in setting it up but the Wolfwave has a broad range of settings for NR.
This is a quick and dirty example of using the Noise Reduction function of the Wolfwave. I'm not a big fan of using NR on radios generally as it can sound awful if not perfectly set up. As a result I'm not proficient in it's use but hopefully this gives you a feel for how the Wlofwave NR sounds: czcams.com/video/vyBP7nihu40/video.html
@@g0pot I completely understand why you don't like the awful under water effects resulting from most noise reduction schemes.
so far it seems wolfwave is just as bad as the worst of them in this respect.
I am very impressed by BHI noise reduction, on it's lower settings ( 1 or 2 out of 8 ) there is absolutely NO underwater effect whatsoever and it actually reduces lots of noise magically without reducing the highs or crispiness, it is however designed only for ssb or am type bandwidths so its deficiencies are obvious on cw and it lacks any other features or adjustability.
I absolutely love the binaural spacial separation wolfwave offers, frankly that's the only reason I'm interested in it
are you aware of any other piece of gear that does it ?
I'm using an archer video sound processor and its stereo simulator to achieve sort of similar results by analog means
I recommend you try it, they're typically found on ebay for under 60$
I'm also using it to drive an xy oscilloscope display from mono hf audio with amazing results
it lets me really know who has good ssb audio by the geometric patterns generated by their voice thru ratios of harmonic notes -or not
there was someone who came up with a way to phase received cw audio spatially in a room according to pitch , not using headphones, sort of quadrature, eric dollard n6kph mentioned it but info is very scarce....
does this work on 2m?
Fernando F. As this is an audio processor you can use it on most radios and, indeed, on anything with an audio output. As well as using it to filter out noise on SSB and CW I also use mine a lot for cleaning up AM broadcast stations.
@@g0pot thank you for getting back to me. I'm about to pull the trigger on this, I'd like to use it both with the 817 and the VX-1700 (HF) I've noticed its particularly tricky (VX1700 HF) as not all the speakers/headsets I've connected work, according to the manual its a 3.5m jack with impedance from 4 to 16 Ohms. will this work ? thanks for your feedback
Fernando F. The Wolfwave has two outputs, one designed for headphones and one designed for speakers. You can even adjust the gain of these in the menus to make it easier to swap between phones and a speaker without having to adjust the volume and you can choose which stereo input channel is used for the mono speaker output (L or R). For the headphones you can swap L/R and adjust the L/R balance.
why do the knobs wobble when you turn them ?
The knobs have the normal amount of play in them I would expect...I have my Wolfwave attached to my KX3 here and the play in the knobs feels very similar. The Wolfwave Multi Use encoder has less play than the volume which I think is pretty typical.
@@g0pot yes it's pretty typical of today's cheap hardware.
very unimpressive.
you do not have to lower your expectations or you become complicit...
mono input or 2 channel input ?
This is a really interesting question and not one I had checked before as I only use it on standard Amateur Radio gear with a mono output. The Wolfwave input appears to be mono (left channel if you use the stereo / dual mono output from a radio) and it can generate a pseudo stereo effect using it's binaural mode(s) which I really like. This isn't a processor to use with a genuine stereo source I would say.
@@g0pot well, even some of yesteryear's amateur radio gear used stereo output
Yaesu ft 1000D allows you to send main receiver audio to left and auxiliary receiver to right channel for some interesting effect which adds depth to the sound field (problem is 10hz min tuning step)
some of today's dual receiver radios do as well
if wolfwave is mono input only that is a serious limitation which must be mentioned
perhaps a way to gang up two wolfwaves should be considered.... LOL
the "designers" these days have no imagination....
So it’s just a glorified parametric EQ?
Maybe a super specialist EQ :o) The filter shaping is excellent and with multiple notch filters, noise reduction, binaural enhancements, CW decoding and much more it makes a nice little audio processor unit.
What's a walwort?
10thumbstrum A wall wart is the American name for the small power supplies that you use to charge phones and power small household items.
@@g0pot Ah, OK. Not heard that term before... don't think I'll be adopting it any time soon though - it sort of sounds like a suspicious growth or something. Plain old "power supply" seems more logical. Great review btw. Looks like a quality product.
10thumbstrum :o) Many of my viewers are American so I try to use both English (European) and American terminology and measures to be as inclusive as possible. Idioms and pronunciations are fun and weird though for ‘foreigners’! Glad your enjoying the videos...I need to get a few more finished.
