I am wondering, would it be feasible to add some PPS clock synchronization feature? GPS chips are cheap nowadays and an accurate timestamp could help obtain rough location data for specimens if several recorders were deployed in an area.

Aloha, This past weekend I went out to replace memory cards and batteries for my devices. Arriving at the song station, I flipped the switch from "Custom" to "Off", replaced SD card and batteries, and flipped switch back to "Custom" to return to the recording schedule. However, I received error messages (green + red blinking lights). I understand this error while switched on "Custom" signifies there is no time set or recording or no recording periods set, but this can't be correct. Three weeks ago I tested out each AudioMoth at my office to ensure it followed the desired schedule. Check. The following day when I deployed my devices I only deployed an AudioMoth if it blinked red OR green, indicating that the device was following my custom schedule. Check. But this past weekend I received this green + red error message during my first attempts to replace SD cards and batteries. This is evidently a user error, so I ask of guidance from the community. Mahalo for the help. Andre

One suggestion: it would be great if the files could be expanded to 5 seconds or 3 seconds (for comparison to the files my other detector produces). Thanks
