Hank did a battery endurance test today that went very well. He transmitted into a dummy load for 4 hours straight and the battery was still going. For a rocket flight we don't need more that an few minutes of run time, but if the transmitter is on anyway, we can use it as a radio source to find the rocket if it is lost or blown far away. We'll use a directional antenna to zero in on the transmitter and may even have a visual clue of where it is we looking at the video.
We'll do an actual range test sometime next week.
