Troubleshooting Radio Circuits A Practical Guide
A practical article explains common radio receiver faults and fixes. It outlines three fault types open circuit short circuit and leakage and describes a simple ring test using a series lamp to detect an open circuit in components like a tuning coil. The guidance emphasizes careful inspection and logical testing of contacts and wiring.
Testing the Tune Circuit and Grounding for Radio Antenna
Testing the tune circuit requires sliders to move freely and a continuous light. If the light goes out with the coil jarred, contact is poor. Use a buzzer and battery in series with clips to test for open circuits and low resistance grounds. Do not test the house lighting circuit for grounds. Grounding must be verified between ground wires and pipes. Leaks often occur between antenna and ground. insulate the antenna and route the lead-in to avoid grounding paths when wind moves it.
Testing Telephone Cord and Crystal Detector Care
Instructions describe testing telephone receivers by tongue contact, checking diaphragms, and ensuring continuity. It covers adjusting diaphragms, avoiding wire damage, methods for identifying open circuits with shorted receivers, and cleaning crystal detectors with alcohol or renewing the surface to restore signal strength.
Amateurs Should Play Fair in Radio Communications
Radio Inspector L R Selmidt urges amateurs to follow regulations to avoid restrictions. A government printing office pamphlet costs 15 cents and outlines minimum power use, 200 meter wave length, and sharp, single dominant wave with limited energy in secondary waves. Operators should avoid excessive calling, using three calls and three de signals max, to maintain orderly airwaves.

Montana wartime notes and local updates ricochet across the state
A roundup of Montana items reports grasshoppers near Lavina and deaths in Missoula and Hamilton. Fires and closures follow lamp blasts at Granite and the Tri dent cement plant. June 20 is named good roads day, while graduates, rail incidents, and local authority actions fill the week with civic notes.

Radio aerial tuning tips for stronger signals
The article explains that higher aerial height improves signals with five to ten feet increases. Adding a variable condenser to the secondary or primary of a loose coupler helps tune out undesired signals. Solder a flexible wire to the slider to reduce contact loss. Increase spreader length for multi wire aerials to ten feet and keep wires four to six feet apart for best results.
Grounding Aerials to Prevent Lightning Damage
The article explains that aerials can store atmospheric electricity and should be properly grounded to act as lightning rods. Fire underwriters require a copper grounding wire no smaller than No 4 gauge, run directly to the outside ground. Inside pipes cannot serve as ground due to risk of fire and loss of life.
Gould Estate Trustees Appointed After Jay Gould Death
In a New York legal action the court enjoined Jay Gould and Myron Herrick from pressing a $644,904 claim against the late Jay Gould estate. Justice Delehanty, with the consent of six Gould children, shifted estate management to four trust companies and appointed new trustees for Edwin, Frank J., and others. The Princess Vlora of Albania and Mrs Helen Gould sent their daughters to America.

Thompson May Take Yacht Trip If Re elected
Chicago Mayor William Hale Thompson reportedly eyed purchasing the luxury sailing yacht Undaunted in New York with plans for a globe circling voyage. The 198 foot vessel, owned by Francis Mayer, is in receivership at $100 000. Thompson, George F. Trarding and Eugene St. Pike form a Chicago syndicate to buy it.

Beveridge Wins Indiana Senate Nomination Over New
Albert Jeremiah Beveridge defeated Harry S. New to win the Republican nomination for U S senator in Indiana by about 20 000 votes. Samuel M. Ralston led a Democratic field to a moderate landslide within his party. Beveridge pledged to honor party unity while the Republican committee praised his twelve years in the Senate and vowed to support the chosen ticket. He was born in 1862 in Ohio and rose from laborer to lawyer and orator.
