Thanks Bill. I'll take a closer look with magnifying glass at the electronics for any obvious/not so obvious corrosion. Is there a product to apply to electronics for preventive maintenance in this application or just go back to the old balloon and rubber band? Going to the pond tomorrow so some skippers will have this same equipment and should be willing to let me troubleshoot by going through the binding routine with combos of theirs/mine. Thanks again, Fred F.
