B,N Brown W88ELK ~ 73 Magazine ForsstRoad Hancocll NH 03449 Cross--eountry ATV Adventure! On a clear morning this spring. me door 10 a large blimp hangar in Orange County, California. will open to reveal a 75-loot diameter balloon. a gondola suspended high in the air just below the balloon, and a large ball ast balloon on the ecncm (see Photo A). Thr,*, daring balloonists will ride in the qcndola as they attempt a nonstop crosscountry Ilight. This is a warm-up flight for thei r nonstop round-the-world flight scheduled lor th is November. Dubbed Earth · winds, the November flight will fly in the jet stream al a constant altitude of 35,000 teet . The three balloonisls will ride in a special pressured gondola (see Photo B) SlJspended between the helium balloon and a unique ballast balloon. The ballast balloon is what makes the mission possiblv. tis weight can be adjusted by varying its inlernal pressure through means of a highpressure fan and release valve . This means that V61'Y little ballast needs to be carried, resulting in very long f1ighl duration ceoeoarnes. If the winds are favorable, it should take from 11 to 20 days 10 ci rcle the globe. Onboard the gondola in November Will be captain Larry Newman KB7JGM, Ma j . G en. Vl adimir Dzhanibe ko v Number 21 on your Feedback card Work a Balloon PholO A.

Since flying with the historic trans> oceanic balloon crossings 01 Double Eagle II (Atlantic) and Double-Eagle V (Pacific), Larry Newman has dreamed of the ultimate ballooning conquest 01 a nonstop round-the-world flight. Aller years of planning, it could be a reality this spring. Larry KB7JGM. a very enthusiastic ham, is quite active on 10 meter SSB (recently he' s be en found around 28.385 MHz). He is a pilot with America Wesl Airlines (see Photo C), and soon plans to operate on 20 and 15 meters while on his twice weekly coast-tocoast Boeing 757 flights. During th is spring's balloon test night. he will be activeon 20, 15 and 10 melet$, Listen on 28.385, 21.385 and 14 .330 MHz lor KB7J GM/balloon throughoul the night. When Larry is not operating live lrom the balloon , he may have a talking-voice beacon operating on 28.385 MHz to relay their altilude and posilion. Hopefully schools nationwide can monitor these transmiSSions and plot the balloon's path as It drifts across the country. LIve ATVfrom 17,500 Feet In addition to l arry's HF activities, he plans to operate a com plete ATV stalionl A live color camera ettached to Ihe railing 01 the gondola can be remotely pointed via a 2 meter control link when larry is busy with other activities. When Larry is not receiving ATV, he'll be tr ansmi tting spectacula r .,iewS o t the Earth below ttlllt can be seen o n 434 MHz (439.25 MHz aJtllfnate). Those of you with cableready TVs or VCRs can tune in on cable channels 590r 60 (as tong as you connect an ootside antenna ). Since lhey plan on flying at 17,500 feel lor the c ross~u n try effort , anyone within 160 miles of Ihe flighl path should be able to view the ATV signal or contact Larry on 2 metars. He will be mc nucring 144.34 MHz FM as well as the HF Irequenc res. l arry c an oper ate with either vartical or horizontal polanzat-on on ATV. During each night, there is the possibility 01 a cross-band ATV repeater mode: 434 MHz inpul/1255MHz 0U1pUt (AM or FM). Two lines 01 telemetry will be displayed at the ecuom of the screen showing the allitude, latitude, and l0ngitude; and the temperature, ground speed, and heading. This is acc0mplished with the aid 01 a Magellan GPS (Global Positioning Satellite) receiver interfaced to flight compUler/video overlay board availab le Irom High Technology Right. The telemetry CM:Iflay system was Gesigned by Bob Rau N81YD and is similar to Ihal used in previous balloon experiment s (see High Altitude Ballooning.

Desert Voices Continuedfrom page 18 case another message come:" through, and not bother with seeking publicity. The gratitude and recognition ofthe people you help may be enough fo r you personally. But no publicity means the la rger community remains ignorant ofwhat you 're are doing. In fact, many people have only 'a vague idea ofwhat a ham is or does. and some may wonder if there is such a thing as a ham anymore. For example, in the first 38 years ofmy life , lived in five different parts ofthe country, I only met ONE ham. Though I knew him for 10 years, I didn't know he was a ham until I moved a couple ofthousand miles away and began workingfor 73 Magazine-and received a letter f rom him' Hams love to rune in the world on the air-but they forget to tell the world in person. Young people are especiallyaf [ected by this lack ofan imagef or the amateur radio operator. If they have neverheard about amateur radio or mer a ham, they cannot easilyp icture them in their minds. Yet young recruits are what am£lreur radio needs most of all.
