Where, in that country, they had seen big concentration camps, and men preparing for war, with an occasional evidence of wars effects in a building wrecked by a night air raid, here, in the eastern ... http://radioshack.blogchili.com/but-their-trip-now-was-far-different-from-the A 25 to 50 Mile Wireless Telephone Transmitter--With Direct Current Motor Generator.--Where you have to start with 110 or 220 Southwest Colorado Tv Translator Association K24ch volt direct current and you want to transmit to a distance of 25 miles or more you will have to install a _motor-generator_. ... http://radioshack.blogchili.com/a-25-to-50-mile-wireless-telephone-transmitter He flashed his light about the hole. It was difficult to tell where the opening had been. "Joe and Frank Hoskins!" cried Jerry, a new terror in his voice. "I heard Joe shriek!" Slim, catching his meaning, snatched a rifle from beside one of the bodies, and with the butt ... http://radioshack.blogchili.com/he-flashed-his-light-about-the-hole He then gave each of the boys a pass, and told them to be aboard the _Everett_ not later than half-past ten oclock, and departed for the special work to which he had been called. "Wouldnt you like to be a lieutenant, though?" exclaimed Joe enthusiastically. "Just imagine being called ... http://radioshack.blogchili.com/he-then-gave-each-of-the-boys-a-pass CHAPTER XV OPERATION OF VACUUM TUBE RECEPTORS From the foregoing chapters you have seen that the vacuum tube can be used either as a _detector_ or an _amplifier_ or as a _generator_ of electric oscillations, as in the case of the heterodyne receiving set. To understand how a vacuum tube ... http://radioshack.blogchili.com/chapter-xv-operation-of-vacuum-tube-receptors Seeing no one that he knew, and his mind weighted anyway with the menacing mystery of the strange happenings of the night before, he sat down on a coil of rope, just in the lee of the forward smokestack, to think the whole matter over for the twentieth time. He ... http://radioshack.blogchili.com/seeing-no-one-that-he-knew The energy of these oscillations sets up oscillations of the same frequency in the secondary coil and these high frequency currents whose voltage is first positive and then negative, surge in the closed circuit which includes the secondary coil and the variable condenser. At the same time the alternating positive ... http://radioshack.blogchili.com/the-energy-of-these-oscillations-sets-up-oscillations Now bring a pair of _No. 12_ or _14_ insulated wires from the 110 volt lighting leads and connect them with a single-throw, double-pole switch; connect one pole of the switch with one of the posts of the primary coil of the alternating power transformer and connect the other post ... http://radioshack.blogchili.com/now-bring-a-pair-of-no A Two-wire Aerial.--An aerial with two wires will give better results than a single wire and three wires are better than two, but you must keep them well apart. To put up a two-wire aerial get (1) enough _No. 16_, or preferably _No. 14_, solid or stranded copper or aluminum ... http://radioshack.blogchili.com/a-twowire-aerial CHAPTER VI HOW THE TRANSMITTING AND RECEIVING SETS WORK The easiest way to get a clear conception of how a wireless transmitter sends out electric waves and how a wireless receptor receives them is to take each one separately and follow: (1) in the case of the transmitter, the transformation ... http://radioshack.blogchili.com/chapter-vi-how-the-transmitting-and-receiving
