Thank you for the response.

Hi Jay. I hope all is well. I apologize for the many attempts. The temporary email address worked well. I received your message but got so excited that I refreshed the page, erasing the message you sent me. I tried emailing you from the glance I took at the message before erasing it and was not succesful. Can we try this again? Below is the temporary email address. I apologize for the inconvenience and I really appreciate your time and effort. Sincerely, Carlos cesey54414@bymercy.com

Hi Jay I hope all is well. Sorry that this message took so much time but I was able to get a temporary email address. If you wish you could send me an email to this address and then I can reply with my personal address. The email below will only last a few days. Thank you jifat79372@usharer.com

OK I will thank you.

Hi Alex. I purchased eight units from Group Gets. Only 2 of them had this issue. I was able to program them but after an hour they had shut off and where warm. After that they had that power surge message I mentioned earlier, every time I tried to connect them and now they do not turn on. Not even on Default.

Hi Alex. Thank you for the response. I updated the firmware version of the Audiomoth. I have a 1.2.0 model. Will I be able to use the magnetic switch start, with this update? Thank you

Hi, Thank you for your response. I tried turning them one with just the batteries in DEFAULT mode but nothing happened. I guess hot glue may have shorted the board there was a hot glue link between the negative terminal from the power source and the microphone connection.

Thank you for your quick response. I was able to perform a test to measure SNR on a signal on two different recording systems units at different distance from 1 meter to 100 meter. I would like to discuss this in further details, but cannot think of a way to communicate. I also do not want to publish my email address here. However, I appreciate the time you took to respond to my message.

@jaybarlow33 Dear Jay, Hope all is well. I recently built a recording unit with the H2A and an Audiomoth 1.2.0 to record fish sounds. I was able to record some fish sounds and would like feedback on the unit I built in terms of sound quality. I can share pictures and audio files with you if that's okay with you. We can also communicate through email or phone. Thank you, Carlos

Hi Alex. These are all very helpful comments. I ran a bench test and everything was working fine. When I came back from the field I was tired and clumsily pushed the switch from custom to default by accident and then to USB/off again. That may have erased all the previously collected data. I also tried to look at the comments in the files like the picture you sent but cannot see it. I am using windows and I thought I could reach that windows through the Properties menu. Thank you for your response. I will do another attempt at the field test and keep you posted.

Hi, Alex Rogers. I hope you are well. Recently I went out to the field to test the audiomoth SNR on underwater recordings taken with the H2A and compare it to other underwater acoustic dataloggers available in the market. Unfortunately, after I had program the audiomoth I waited for the first programmed recording cycle to start and it did work well. I headed out to the field to run the test's but the audiomoth stopped recording and I do not know why. Attached are the recorded files (the two that cannot be uploaded are the ones that worked, but they are different lengths). I will appreciate any feedback on this issue. Thank you!

Hi Alison. I am using an Aquarian H2C fitted to an audiomoth. Currently I am doing the waterproof testing to see if the unit holds. Next steps, which are comin soon is to compare SNR between the unit I am building and acoustic dataloggers currently available in the market. Thank you.

Sorry this was the chart I was going to send you. It is an HTI-96min with pre amp

HI Alex . Thanks to your help I was able to get the audiomoth to record on schedule. However I believe I need at least 5-10V to power the hydrophone I wish to attach and I believe that is why audiomoth cannot turn on the hydrophone. If I connect only the signal cable to audiomoth and power the hydrophone independently. Will the pieces be able to communicate with each other through the signal cable? Thank you the signal cable?

Thank you very much Alex. What would be the recommended voltage, 4.6V?
