Rodney Vambrisk describes a compact two tube radio set usable for city or country use. It covers distance, volume, and selectivity with a 0.0005 to 0.00025 mfd tuning condenser and a tickler, using dry-cell tubes like the 29. It fits in a small cabinet indoors or outdoors between trees, with a 75 foot antenna and a ground made in moist earth.
The article explains tone controls on newer sets and the solid therostat on the B eliminator as a regulator for amplifier tube current. It suggests adjusting during operation to notice tone changes and occasionally tweak during broadcasts when voltages vary to ensure optimal sound.
H J Dana describes an automatic relay switch for radio sets, aimed at hobbyists. The device uses a %-inch round iron core, a hinged armature, a brass yoke guide, and adjustable spring contacts adapted from a Ford vibrator. Coils require about 200 ampere turns, with a 600 turn magnet wire winding on a %-inch core, connected in series with the A battery and the A G supply line.
Practical guidance for early radio work covering battery care tube storage and handling, resistance to electrolyte creep, high tension work safety with rubber coated pliers, proper mounting of detector tubes, tin foil composition in condensers, sound radiation from speakers, ground versus antenna effectiveness, detector tube mounting, soldering cautions, and trickle charger usage for storage batteries with vent caps removal guidance based on charge rate.
The article warns that poor tubes increase battery drain and suggests testing tubes periodically. Discard any that do not meet the average standard to avoid higher battery consumption for the same signal strength.
