An Amateur Radio Power Supply from Junk


Alan Drury G4FZP will show us how an old ATX power supply from a PC that would otherwise be destined to the tip can be repurposed and modified. The resulting modification, using only three resistors, is an Amateur Radio Power Supply giving 10A at 13.8V.

Note: Please observe safe working practices when working on mains powered equipment, and only do so if you are competent to do so.
