Pigeon Fanciers Fetch High Prices for Homing Birds
Fanciers set high prices for homing pigeons with some birds selling up to 200 dollars each. Owners grow attached to their birds much like dog or horse enthusiasts. Homing pigeons boast endurance, flying 12 to 16 hours without rest.
Weighing 16 Ounces Will Consume One Ounce Daily
A note notes a device or plan that weighs 16 ounces and uses only one ounce of food per day. The description implies a compact efficiency design for reduced consumption.
Cattle Losses from Lightning Across Fences
The article notes most cattle killed by lightning die after drifting into wire fences during storms, with fences dragging the bolt to the herd. Direct strikes are rare and usually occur under trees.
Mystery of Radio Prompts Fresh Engineering Questions
The article outlines ongoing uncertainties in radio science including short wave transmission, ether nature, aurora and sun spot effects, and dead spots. It notes experiments limited to mobile control and light transmission, while highlighting radio’s wide uses in relays, navigation, rail safety, and time signals.
Audio Amplification Intensely Developed
The article outlines three major audio amplifier types transformer resistance and impedance, noting modern transformer systems dominate due to broader band reproduction and improved materials. It highlights high voltage power amplifiers and a radio power supply unit delivering 35 milleamperes at 200 volts with adjustable detector and intermediate voltages to optimize tube operation.

Greater Volume Tone Improvements in Radio Receivers
The article explains how newer tubes like CX-171 and CX-371 boost volume and tone by optimizing plate voltage and bias. It notes 180V plate and 40V C battery as ideal for sensitivity, warns against 200V B battery due to space and maintenance costs, and describes the need for higher current. It also mentions eliminating B batteries with house lighting power via rectified AC supply.
Proper Battery Connection for Radio Set Safety
Connect set first to battery binding posts to avoid crossing wires. If reversed, ends may touch incorrect posts on the receiver and cause trouble.
Oil Lubrication Insight for Condenser Bushings
The text explains avoiding oil on a condenser relation and using oil to lubricate bushings of a variable condenser. Oil forms an insulating film on contact surfaces, spacing them a fraction of an inch apart and insulating the two points where contact is desired.
Dust In Circuits Needs Prompt Cleaning
A film of dust or dirt between binding posts on radio gear acts as a resistor and can affect sensitive circuits. Keep equipment clean and remove any accumulation with a stiff brush at once.
Ground depth affects electrical grounding efficiency
A U.S. Bureau of Standards study shows ground resistance varies by location. Sandy soils and deep moisture levels require deeper iron pipe grounds to reach moist soil for effective electrical grounding.

Hints for Radio Fans and Antenna Care
Hints for radio fans on tube voltages and building a quiet antenna. It notes how signals penetrate insulation, the need to lower the antenna to clean insulators, and how to revive a crystal detector by soaking in ether and shaking.
Distortion Sources in Sound Systems
A loudspeaker rarely causes more than 25 percent of distortion. The amplifier accounts for about 40 percent of the blame, while tubes contribute the remaining 25 percent.
Safe Antenna Setup Says Never Anchor To Unstable Structures
The guide warns not to secure aerial guy wires to unstable structures like chimneys with loose bricks or to rain spouts. It recommends using No 14 iron wire or heavier for stability and safety.
Tuning a Fixed Coil with Condenser or Variometer
The article explains two methods to tune a fixed coil using a variable condenser or a variometer. The condenser can be connected in series or parallel, while the variometer is applied only in series.
Tiny light-socket powered fan invented
A compact electric fan device can be screwed into a standard light socket to operate without separate power connections. The invention uses existing household wiring to spin blades for personal cooling.
Have Kidneys Examined By Your Doctor
Flush your kidneys by drinking a quart of water daily and take salts to neutralize acids believed to injure kidneys. A pharmacy remedy called rad Salts, a lemon grape lithia mix, is advertised to cleanse sluggish kidneys and relieve bladder weakness with a fizzy effervescent drink.
