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.
