    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! Regards Will

    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.
