Hello,
I am new to balloon launching. 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.

Good luck.

Should go up to 100k feet and then come down not far from launch.  Be heard across 15 states.
 
Though it is a non high altitude GPS and FIX will be stuck above 18k feet until it comes back down.
 
Callsign is W3ADO-11 and it will be on 144.39
 
If anyone KNOWS that a Tinytrack3 and GPS2 from Byonics will *not* re-aquire when it comes back below 18k feet please let us know NOW.
 
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.
