Not illustrated. 1914 edition. Excerpt: ...and pair of receivers. C. K., St. Louis, says: I should like to know what I require to receive the time signals from Arlington. At present I am unable to hear them. My set consists of an aerial 78 feet high, 85 feet long, composed of four 7-strand No. 20 P. B. wire; lead in 80 feet long, 50 feet of which is 7strand No. 18 copper rubber-covered wire. Ground lead, 7-strand No. 18 copper rubbercovered wire to the water mains. My receiving set consists of a Blitzen receiving transformer, Blitzen variable condenser across the secondary windings, Audion detector, one pair of Hotlzer Cabot 3,000-ohm phones and fixed condenser. am using a loading coil wound in grooves--130 turns; taps are taken off every 14 turns. Is this correct for 2,500 meters, or what would you recommend me to use to receive time signals from Arlington. Ans. (1) We have taken note of the diagram enclosed with the query and find it is quite correct, with the exception that the fixed condenser is connected in shunt to the headphones and not in series; for if it were connected in series the local battery current could not flow through the telephones. We are not familiar with the wave lengths obtainable in the secondary circuit of the Blitzen tuner. Probably there is not sufficient wire to reach a wave length adjustment of 2,500 meters.
