I need to get the campus and federal Ok to go for this, ive heard of high school students doing this first a few years ago.

Been meaning to send something above the Armstrong line for quite awhile now, soon as i get the HV probe working this is next.

We did this at our school. It is super easy and super cheap and super fun! There were ten payloads that each had an experiment on board as well as a camera. Below is the picture from our max height, 96,000 ft.

A GPS beacon. Ours also had a short wave beacon like those used in geocashing.

Lol as far as I know, wanting finding something doesn't mean you're a terrorist! smile

We had the coordinates transmitted over CB radio to receivers set up connected to laptops. The laptops then put the coordinates overlayed on google maps to help us chase it down. It was a pretty sweet setup and over the past ten years a payload has never been lost, even when farmers find it first and hold it hostage!

Serial data transmition? I assume that CW radio can be frequency modulated to carry a signal.

How powerful was your CW? In terms of miles..
