APRS Balloon Payload 2

A small wood frame has been built for the APRS tracker that will be placed in a foam box. The GPS receiver is mounted at the top of the frame facing up and the transmitter and tracker boards are below. It is sitting on top of the battery pack. The plan is to use lithium AA batteries. The pack is a 6 cells which should deliver 9 volts.

I am working on the dipole antenna that will be mounted to the side of the foam box. I also need to setup a regulator for the transmitter since 9 volts exceeds it's max voltage.
