    Wolfwave advanced audio processor

    Posted by Richard on 19th Sep 2019

    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.

    It's okay!

    Posted by Burmeister , Dieter on 1st Sep 2019

    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!

    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.

    Extremely effective

    Posted by Michael Granatt on 13th Jul 2019

    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.

    I've been using the Wolfwave now for a week and it is outstanding. Firstly it arrived in good time and well packed. I first powered it off the USB lead supplied and I was surprised at how intuitive it was to use. I have it connected to my ICR8600 and now powered off a 12Vdc station supply - it makes a real difference to your listening experience. The Wolfwave is so configurable and being able to move the centre frequency and alter the bandwidth so quickly is a dream to use AND you don't have to keep going into the radio menu to make adjustments. Lots of memory options makes it easy when using a general coverage comms receiver as you can load new settings at the press of a button. The rotary encoder is so easy to use and you can configure the gain to drive your speaker - be sure to have a station supply connected before you turn it up though - the team advise this. The noise reduction is superb and has terrific range, far more configurable than the ICR8600. The age compensation function works well and is noticeable, helping me pick out weak signals when the signal is drifting.

    What a terrific little box, real magic! I'd recommend it. Well done the Sotabeams team a fantastic product!

    Wicked Little WOLFWAVE

    Posted by Adrian M0PAI on 1st Apr 2019

    Very neat little box, looks and works great.
    Makes a great improvement on the RX audio and very quick to adjust when needed.
    The WOLFWAVE is a great little addition to the shack and I would highly recommend it.
