Pond Station “Fall Cleaning”

I’m at Wave Farm this weekend, giving Pond Station some TLC. These hydrophones sound OK but they’re showing their age. Time to make some shiny new ones!

No sign of the beavers this year, so I removed the “beaver-proofing” that was compromising sound quality last year, and did some preamp modifications to open up the high-frequency response a bit. I made tripods to mount them on, so they sit off the bottom a bit and avoid sinking into the muck.
