> Hi, is anyone using a laptop pc type charger/psu to charge their K2 internal > battery? I successfully modified a Toshiba laptop power supply to power my K2 a couple of years ago. I was able to open the unit up and change a resistor in the regulator circuit to provide 14.1 volts output to the K2 and its internal battery. Give it a try. 73 Rick VE3MM
