| The receiver is comprised of a variable oscillator operating on the received frequency, a mixer and high gain audio amplifier. The received signal is converted directly to audio where a filter eliminates undesirable signals, and then amplified to headphone level by a high gain audio amplifier. The variable oscillator covers 7.0 to 7.3 MHz for 40 meter operation and is doubled to 14.0 to 14.6 MHz to cover 20 meters. | The receiver is comprised of a variable oscillator operating on the received frequency, a mixer and high gain audio amplifier.
