Jupiter Io-B/Io-C on 17 April 2009
For this experiment, we used an Icom R-75 HF receiver tuned to 20.1 MHz (in LSB mode with AGC Off). The antenna was a 3-element Yagi initially pointed 135 degrees true and rotated every 40-50 minutes to track Jupiter as it crossed the morning sky.

swishing sounds of L-bursts; there is a relatively strong burst toward the end
of the file.
