Hydrophone speed calculation
I have been practicing this for awhile but I cannot get the hang of it. I have CAWS and it has a draggable chart for the speed calc. But I cannot differentiate when the chug-chug-chug begins and ends to time the cycles. What am I looking for?
I have read many people's ideas how to calc, I just need to know what I am listening for. Where is the break to determine when the RPM begins. What is the technique?
