    Hi Brad.

    It might be a usefull thing, but it doesn't do wonders.
    I have build my own noise-canceler about 10 yrs ago , it works on the same principal as the time-wave or MFJ units.
    But I have build it myself, it costed about $15, it is still in use nad is placed under my rig so it doesn't take up room.
    Also the German hamradio leage (DARC) sells a kitt fore homebrewing such a device.
