    Not much information about the circuit on the web site. Wish there more more.

    The kit has a rock solid tx circuit by using the TX ground and the relays are put in series. This is far more reliable on ssb than the German vox design.
    The Wimo X-Phase has the same vox problem causing uncontrolled switching of the relays.

    What is your antenna configuration, especially what is your noise antenna?
    Does it work on the higher bands too?

    I have some local noise here from a certain direction and I am thinking about similar noise cancelers. I found some designs in the RSGB handbook, but they are for the 137 and 472 kHz bands.

    What instructions are provided with the kit? I'm a novice kit builder at best, what is the level of difficulty with this? I could certainly use this kit at my QTH.

    The noise antenna is a wire around the windowframe of my shack . length aprox 6 m.
    So all angles of noise signals are received


    Simple instructions are privided for this is a easy to build project. The only difficult part could be the connection to the TX ground of your transceiver.

    As for instructions....have you ever considered studying mind reading ?

    Scant and badly translated are the words I'd use as my son and I are in the process of identifying the components as I type, and I don't hold out much hope for this project ?

    Anyone got any idea where the PTT socket is wired to please ?


    Billy Jr would appreciate your help fellas
