Examples
This method of receiving continuous wave signals is called the “heterodyne” method.
This is spoken of either as the “super-heterodyne” or as the “intermediate-frequency amplification” method of reception.
The connections for the autodyne, or self-heterodyne, receiving set are shown in Fig. 60.
From this you will see that any regenerative set can be used for autodyne, or self-heterodyne, reception.
In using either of these heterodyne receivers be sure to carefully adjust the B battery by means of the potentiometer.
