Important Safety Notice! Like all high power radio transmitters and RF amplifiers, the RF amplifiers, modulators and power supplies described in this document use hazardous voltages. YOU OR SOMEONE ELSE CAN BE KILLED or badly injured if you or someone else comes into contact with any of these hazardous voltages. The power supplies may contain lethal stored voltages even when turned off or disconnected. You cannot be too careful! In addition, All primary (120V and 240V AC line) inputs must be properly fused at the point where the AC line (s) enter the unit. Never operate a piece of equipment which is not correctly fused. To do so creates a fire hazard, the potential for an explosion and an extreme danger to life and property. Heat build-up can cause a fire hazard. If you're not experienced with high voltage, high power radio frequency equipment, get help from someone who is. Do not build any of the equipment or circuits documented here unless you know what you are doing, and fully understand the proper safety procedures and practices and implement these in your own projects. A little common sense goes a long way :=)
