What is Simple Short-Wave Transmitter Circuit about?
This document summarizes a simple short-wave transmitter circuit that is tunable from 10 to 15 MHz. The transmitter uses a 1⁄2J gang condenser and inductor to determine the carrier frequency, which is then amplified by a transistor and coupled to a RF amplifier transistor. Audio input is preamplified and used to modulate the RF amplifier current, producing the modulated signal. The RF signal is coupled to an antenna for transmission up to 75 meters away, where it can be received with good signal strength.
