<p>We just got two st600s back from the field and the data is really really quiet - it appeared to have recorded but it's almost as if the hydrophone wasn't connected and it's just fuzz. These were brand new last year and tested and gain was set to high during the programming. Has anyone come up against this before? Super irritating.</p>

It would be a good idea to check the wire between the board and the HP, as it is incredibly thin. It is the small white wire between the head of the ST600 and the board.The connection may have also popped out, but it is easy to reinstall.

If it is still intact, yes I would run a bench test, and also leave it recording over the weekend in an office to see how it uses battery power over a few days. This info can be found in the log.xml files.

If you still have issues, you will likely need to return the instrument to John Atkins for review.

Good luck!

The only suggestion at this point is to re-test the system:

* Off-load your 'recordings'; one never knows.
* prepare a new recording (make screenshot of deploy control) for some short time
* touch gently the hydrophone and whistle very close
* stop recording
* offload data and check data

While checking the deploy control form, I'm not sure what happens if

* periodic recording is not checked and filled-in
* sample rate is disabled (by mistake)

In case you did keep a screeen-shot of your deploy control form (which is always a good idea) you may check the settings.
