Hints for Amateurs Who Build Own Sets In any circuit where one side of the condenser Is connected to the ground it is best to ground the rotating plates, thus doing away . with some of the hand-capacity effects. For real DX work a 300-foot antenna an-tenna with a series variable condenser works very well. Although this is not as selective as a shorter one, surprising surpris-ing results will be experienced for long distance reception as well as local audibility. This is an old amateur ama-teur stunt. In wiring a receiver set all connecting connect-ing wires should be short, direct and well spaced from each other. Wire used for winding Inductance coil should have as little Insulation Immediately surrounding the wire as possible. This adds to the distributing capacity of the coll and results in loss of power and audibility. It is worth while to use "dead end" switches for disconnecting the major part of the coil when not in use. Why waste power by having the unused portion in the circuit? For clearer reception use a C battery bat-tery in each step of amplification. This will double the life of the B battery, as the plate will only draw about half when a C battery Is connected In the circuit.
