Hi!
There are at least two groups that know of that launch High altitude
balloons with amateur payloads. I just joined one: Arizona Near Space
Research. http://www.ansr.org/
The other s in Colorado, not sure of the organization's name though.

High altitude balloons are fun. There's a group here that launches
You may be making a joke but if we call it Proof of concept mission for the
usage of COTS components we might get a huge grant to make it happen. It
reminds me of the Surrey Android phone in space. I wonder what if that worked?
From:
yes, thanks to all control operators here and abroad, but especially those from
the AMSAT-NA team who worked so hard in keeping AO-51 on for as long as it has!
I've made my first contact (WD9EWK) on AO-51I will miss it a lot.

programmed for a 2-meter uplink, add an appropriate local oscillator and high
