Q. How does WOLFWAVE compare to other similar portable devices? A. Click here for our handy comparison.
Q. Can I try WOLFWAVE before I buy one? A. Yes you can. Make a high quality recording of some audio that you want to hear processed (max. 2 mins.). Upload it to Clyp.it (free) and send us the link. We will process it and let you hear the results.
Q. Will a WOLFWAVE improve the filtering in my FT817/818
A. Yes. The attached plot shows the standard FT817/818 filter (green) and the addition of a WOLFWAVE (blue). the difference in skirt selectivity is huge.
Q. Is there a desk-stand for the WOLFWAVE?
A. Yes, you can 3D print one thanks to Nicolas F4EGX.

I need all the help I can get when it comes to copying the code. As an aspiring CW operator, a crowded and noisy band can be impossible to navigate at times. The Wolfwave has opened up some new vistas while I operate from my noisy QTH. To my ear, this device does a better job than my IC-7300 at filtering adjacent signals or band noise. When properly set, the "CW Regeneration" feature is almost mind blowing. The morse decoder also works well. New features seem to be added on a regular basis and are simple to install. There is a novel "band stop" filtering feature which I have yet to explore. The regular bandpass filter is intuitive and simple to operate. I love the flexibility of being able to move the Wolfwave between my rig and my computer, where I often use it to copy from the Web SDRs across the world. My only (minor gripe) is that the controls and menu system are not the most intuitive or easy to operate. There is a bit of a learning curve to get the most out of the device. But all in all, kudos to the Sotabeams team for a novel and and powerful new tool.
not as good as i hoped for could do with interface to computer screen a bit small with my failing eyesight price bit high
NEED BIGGER SCREEN AND MORSE DECODE NOT VERY GOOD. [Admin: thank you for your feedback. I am pleased that in general it works well for you. It sounds like you may have some settings wrong for the Morse Decoder. Please get back to us if you need any help.]
I was really impressed about the possibilities and functions. Also the possibility for futures options.
The Wolfwave unit has made a big difference to all of my radios but especially to my home brew equipment. All the filtering, noise reduction and bandwidth, band stop etc work very well. I mostly use CW where the CW reader has been very useful when receiving fast CW, (above the speed that I can read!!. It’s better than my KX2 at reading CW). The screen is very clear but a little small. The help button is very useful but a hard copy of the help notes would have been good. Early days, but so far it works very well.
Excellent device that works much better than the built in factory fitted DSP noise cancelling on my rig. It has transformed a 30+ year old HF rig to such a degree it's now in daily use and my 4 year old radio gets little use. CW decoding function also works very well. I can't recommend this enough.
I use the "wolfwave" since two weeks! Here we get strong QRM on the lower bands! I can make QSOs now, which without this wonderful thing were impossible! Special in a contest it was very helpful! I use it every day now! Thanks to the om's for so an useful idea! Vy 73 es gl de "Ter" / DK5ZX!
WOW!!! I watched the video and thought "Hey I want that!". After getting it and learning how to set it I realized that this little device is amazing. I could have bought a internal filter for my FT-817 but I use this device on both the 817 and my LNR Mountian Topper 3B. With the LNR it amplifies the audio and takes the (I can't mimic the sound with typed words) out. It is so fun to dial it down to that ONE signal and ignore all the others until after the QSO. Get your's now while products last!!! This is not a paid endorsement. LOL!! The product is just that great!!!!!
I have used the Timewave DSP 599zx for sometime and I replaced it with the Wolfwave. I find this filter much better than the Timewave. There is no ringing and is easy to use the menus. The CW reader is very good but cannot compare it except to my ears and it is reasonable correct, which I am impressed with. I must admit I think this filter is a winner and very much cheaper than the Timewave one which has to be purchases from the states.
Suddenly, my S7 QRM suburban Kent location is transformed. At the first try, Wolfwave pulled an SSB QSO with Belgium out of the noise, using my ft 817. It’s fun to use, and the morse decoder is also very effective.
