They said it could'nt be done. Well I kept plugging away and sure enough, it works great with superb depth and target ID from the enhanced tone. First you need a mono converter. THEN you go into the unit and take out he blast diode. With it your signals will sound clipped and indistinguishable. Today's helpful hint. I think Radio Shack has an in-line audio booster they sell. May add one on top.
