What's a good set-up to transmit the balloon's location down to the ground?
I've looked all over the web and couldn't find a complete solution.
Assuming I have my own GPS modules and an arduino, what do I need for communication (both on balloon and ground station)?
I'd appreciate pointing out specific models - transmitters, receivers, antennas. Note that we have an amateur radio license.
Also, if you could point out a store to buy the equipment (in the UK / EU), it would be highly appreciated.
