Below are links to the .wav files taken from the launch site right up until burst. Using the APRS GPS data, I've included in the table the beginning and ending distance (units of meters) for each files.

The first Close/Far distances are altitude. The Delta-x is the horizontal distance and the final close/far is total distance = sqrt(x^2+y^2). Radio was a Kenwood TM-D710A with a 7dB over dipole yagi antenna.

Attached is a picture showing where the sprite was for most of the flight. It wrapped up on a rigging string and was at about 60 degrees. It was 2pm local time so the sprite would have partial Sun most of the time with peak amounts when it rotated toward the southwest.

The signal definitely was weak at burst, hopefully it has some data in it.

Newly posted files! These were taken by Paul King with a small yagi directional antenna while chasing the balloon. The distance information needs to be posted for these.
