Hi all. Just joined group today. I have an ATU-100 and am confused re the power requirement. The info says 10-15 volts dc range but the internal battery is a lithium 3.7 volt. The input on the schematic by N7DDC shows 12volts with a 5 volt regulator
downstream. This seems logical.
How does a 3.7 volt battery allow the unit to work when the supply is quoted as 12 volts?? Nick. VK4YT.
