But, I have had good luck with a transmitter made from Big Red Bee. It did not work over 40,000 feet the first time. The second time it worked to 90,000 feet. That is when the balloon burst. I have two launches and was able to retrieve latter with in 10 feet of transmition. We also have a spot locater as a back-up. Are balloon launches lasted 4 hours and went over 200 miles. Last one are data sead we reached 90,000 feet. I think we will add more helium to make the flight shorter.</div><div><br></div><div>Good luck.</div><div><br></div><div>Ed </div><div><br></div><div>KF7ZFJ</div><br>Robert Bruninga <bruninga@usna.edu> wrote:<br><div class="WordSection1"><p class="MsoNormal">Launch from Lancaster PA, mild winds.</p><p class="MsoNormal"> </p><p class="MsoNormal">Should go up to 100k feet and then come down not far from launch.

Thanks The rest of the payload costs $10,000 and we don’t want to lose it. It is a different schools project that noone else can access, so I wont bother with details.</p><p class="MsoNormal"> </p><p class="MsoNormal">Bob</p>
