[quote name=\'SkyScanner\' date=\'Nov 2 2004, 01:53 AM\']I had the same problem as you, so opened the scanner up and traced through the circuit with a meter. I turns out that the input goes via a fuse and c-r-c filter to a 7805 voltage regulator - all quite straight forward. Therefore, I would suggest a DC powerpack that provides 6-9 volts should be OK. The positive supply goes to the central pin of the power socket, and negative/ground goes to the sleeve.
