Weather Balloon, GPS, & the BS2
As part of the weather balloon project we are going to need to track it for recovery. We have thought about maybe using a cell phone with GPS capability, but I wonder is there anything in the range of GPS that will work with the BS2?

How about a licensed 2-meter radio operating on 5W with a set of external modems like these http://www.tigertronics.com/rtx12.htm?

You should get at least 25 miles range...

Sparkfun.com has GPS units.
The unit is very small, and has a 300mw output plus it runs on a 9v battery..
Put the chip after it is programmed into the Micro-Trak 300 for a nice unit.

You can buy the XDR-928, but I assume you will need to purchase the receiver setup as well...$$!!
Also be aware of what upper air sites are near you. They may be launching while you are and you'll mess up each others signals.
Also, I'm sure you know that you have to issue NOTAMS for weather balloon launches (we do in Canada).
cheers

"Inside each and every one of us is our one, true authentic swing. Something we was born with. Something that's ours and ours alone. Something that can't be learned... something that's got to be remembered."
I believe the notams are not required if the instrument pack is below a specified weight.
I showed the XDR-928 as an example of the current technology. A number of ham groups are releasing high altitude balloons.
Here is an example of software that will read the digital sondes:
