And General Antenna caused the news of the victory to be carried throughout Pleasant Valley. But when he heard it, after he reached home, Daddy Longlegs laughed merrily. "Why, they never touched me!" he exclaimed. JOHNNIE GREEN couldn't find his new jackknife anywhere.
Our problem is simply to locate the source of the peaks. Somewhere in the circuit there seems to be an effect that serves to modulate the incoming signal. Our antenna will be useless unless we eliminate this interference so that the signal can be pure once again." Rick had seen Sanborn tracings before. The system was a standard method of recording.
The sun blazed down on Sahara Wells. In the distance the pyramids looked hazy, and beyond them Cairo was a thin line of green and brown along the Nile. It was fairly warm in the sun, but a cool wind blew across the desert and coats were comfortable. Rick and Scotty sat on a box under the antenna while Hassan squatted and watched them. For the moment there was nothing for them to do.
They fashioned a two-wire antenna with the spreaders left on the island by Hal's cousin; connected a lead-in to this, and then Cub and Bud climbed the two trees and, with the aid of ropes tied around their waists and the guiding assistance of their companions below, drew the "ether-wave feeler" up to a lofty elevation and fastened it as nearly taut as they could stretch and hold it.
In July 1946, Harry Barnett, a Royal Air Force officer attached to the Press Department of the British Embassy in Athens obtained an experimental transmitting licence from the W/T section of the Ministry of Posts & Telegraphs, with the callsign SV1WE. At that time he was living in a flat in Athens and could not put up an antenna, so it was not until June 1947 that he became active.
I was afraid the large flat top of the aerial would attract thunderbolts. When I finally connected the aerial to the receiver I heard ABSOLUTELY NOTHING." I asked him how he tuned the receiver. He said he had put many taps on the coil and he twisted his antenna to these taps trying various combinations with the tuning capacitor. "All I heard was this breathing noise.
On the under sides of the trunks clung numbers of smaller or more sluggish Longicorns, while on the branches at the edge of the clearing others could be detected sitting with outstretched antenna ready to take flight at the least alarm. It was a glorious spot, and one which will always live in my memory as exhibiting the insect-life of the tropics in unexampled luxuriance.
A tiny point near the center of the screen swelled to a spec, and jumped nearly off the screen to the left. Miller centered it again, and switched to a higher power. This time it jumped less, and resolved into two tiny dots. Step by step the magnification was increased as ring after ring of the lens antenna was thrown into play. Each time the centering operation was more delicate.
This was situated on the top floor, and, as it happened, almost under the scuttle leading onto the roof. This made it comparatively easy to connect up with the antenna, as all they had to do was to bring the leading-in wire through the frame of the scuttle, drill a hole through the attic floor and the ceiling of Bob's room, and drop the insulated leading-in wire through.
Your antenna is connected through an adjustable induction coil, and moreover you have a small condenser which together with it forms a closed circuit. It is simple enough when you understand the principle to adjust the vibratory motion in the antenna by moving the connection. The frequency of the closed circuit can be adjusted, too.
