A good friend of mine has just purchased a Robotalk 2, which has unacceptable switching noise and he has asked me to look at fixing it. He is keen to use it, in his rig, but it's no good in a live situation. Returning it is not so convenient as he bought it from a store in the US who, to their credit, have offered a replacement or a partial refund towards fixing it. Has anyone had a similar problem with switching noise and is there a quick fix. I haven't seen it yet and if someone else has found a solution to this problem and is willing to share the info, it will save me having to fault find it. Thanks in anticipation.
