[QUOTE="KarlS, post: 100502, member: 2409"] I finally finished conductivity switch mod. Does it work, yes. Is it worth doing, I shall see after using it for while. Mod is total reversible. I had removed low battery light and replaced it with a switch. The switch needs to have barell less then 5 mm diameter, got one from eBay. The biggest problem is the connector. After stuffing about six of them, trying to crimp wires with needle nosed pliers, I rang my former work mates until I found electronics engineer has right crimping tool. I have played with it for about ten minutes in my backyard. In eighter mode, low or high it seems to run quiter and transition of the sound from lowest grunt to higher tone is smooth, more like multitone machine, only it is continuing change until it reaches point when sound stops. And opposite way for high tones. I plan to add digital voltmeter to it to replace low batt. light.
