Two Tone Generator - A two tone generator is an essential test gear made with just four transistors that helps you evaluate your amplifiers, mixers, receivers for distortion. Distortion makes all the difference between a pleasant receiver and a horrible sounding one, between a clean transmitter and bad, splattering one on air.

Simple 2-tone generator - A simple 2-tone-generator for testing the linearity of SSB transmitters. This device is as simple as useful. With 2 transistors and an oscilloscope, it is fairly easy to test the linearity of your SSB transmitter. The 2-tone-method is a standardized test method that can be used to determine the maximum output and the amplification characteristics of a sideband transmitter.

2m to 70cm Transverter Circuit - A 70cm / 432 MHz Transverter Project transverter circuit is an electronic device that converts a radio signal from the 2 meter to the 70 centimeter band and vice versa, allowing a single transmitter/receiver to be used for both bands. It consists of an IF stage, local oscillator, frequency multiplier, and amplifier. The circuit must be designed for minimal signal loss, noise and intermodulation distortion.
