Show A High Broadcast Sometime during July Lt.-Com-mander Settle and one of the Pic-card Pic-card brothers will ascend in a balloon for ten miles or so, carrying carry-ing with them radio equipment to broadcast bulletins on their experiences. exper-iences. C. B. Hanson, representing a national broadcasting chain, explains ex-plains the difficulties : "Putting the sending equipment iu the gondola for the purpose of talk rg back to the world wo.i'.d pppear easy," Me. Hanson said "but when even tho food r.hit is canned is governed by the factor of weight, the limitations imposed called for infinite ingenuity. Bear in mind that to reach higher altitudes alti-tudes than man has ever atained, the stratosphere balloon must have a high gas capacity and a light load to carry. Many other things beside radio must be carried. It is planed to carry two persons, a pilot and an observer. "Due to the rarity of air at altitudes alti-tudes above ten miles the gondola gondo-la must be airtight and must be capable of retaining normal atmospheric at-mospheric pressure. Food and water must be carried, as well as oxygen tanks. A maximum of 100 pounds is all that can be permitted permit-ted for the radio equipment." A transmitter weighing only sixty pounds with complete equipment of power and antenna, having an output of about three watts equivalent equiva-lent to that used by an automobile tail light will be used. |
