I built my own RF signal generator by following plans from a Nuts and Volts magazine. In this video, I show how the RF generator works and I go through some of the circuit boards and components installed inside. The RF Generator works from approximately 188 KHz to 125 MHz. I'm hoping this RF signal generator will be useful for numerous tube-related projects (radios, etc, that need alignment). The RF generator is based on an MC1648 voltage controlled oscillator chip and a varactor diode. See my electronics blog at smbaker.com
