Always fun when we have a buzzer oddity. Last night the buzzer went quiet about 2am, but a quiet buzzer could be heard. It faded over the next hour and a series of clicks were heard for about 40 minutes. At roughly 03:10 am the buzzer returned, but sounded like it was being tuned down from a higher frequency. Listening to the following sample while viewing this spectrogram shows what I mean.

Well, if we had an IQ file recording we could probably see more and understand if the buzzer was on a higher frequency for a while before hand, if you have an IQ recording please send it to us. For now, we would not like to jump to such conclusions but interesting stuff!

Also podcast episode 10 is out grab go listen!
