DISTANCE LISTENING
When you are out for long-distance reception and selectivity—the two frequently go hand-in-hand —you want to take the greatest possible care of all the adjustments of the circuit. If you are using a screened-grid stage of highfrequency amplification, for instance, the anode circuit may be brought to the point of oscillation, and the aerial circuit to the same state. In order to get these two critical adjustments, the voltages applied to the anode and the screening-grid of the valve must be adjusted with great care so that the greatest possible amplification can be obtained. The shielding in the set and also the provision of proper bypass arrangements become particularly important, and by careful attention to these it is much simpler to attain the critical adjustments mentioned above without running into oscillation. As regards the grid bias to be applied, it is important not to overdo this, but the exact grid bias voltage will depend upon circumstances.
