One of the ends of the secondary of the induction coil, or the microphone transformer, or the magnetic modulator is connected to the grid circuit and the other end to clip 3 of the tuning coil. A 100 to 200 Mile Wireless Telephone Transmitter With Direct Current Motor Generator.
But the interrogation was over, apparently. Quillan took over the ship controls, and the Commissioner and Trigger went with the recorder into the little office back of the transmitter cabinet, to slam out some fast reports to the Hub and other points. Lyad was apologizing profoundly to Mantelish as they left the lounge. The professor was huffing back at her, rather mildly.
