Thanks again...I have passed this on and hope to have results back in a few days

Hello Alex, The units have been retrieved and here are the test results so far. There seems to be issues with consistent high levels of white noise. Audio Moth Testing – White Noise challenge Units AM 1 using a 128 GB U3 ONN card AM2 using a 128 GB U3 San Disc card R: Recording F: Filtering A: Advance Common to both units throughout testing R: Sleep 5 seconds; Recording Duration 3595 seconds A: Daily folder enabled Play back of recordings on a HP Pavilion laptop with B&O speakers at 100% (Max Volume), otherwise as from factory, the settings. Facing the same direction, side by each Test 1 Both units flashed with 1.8.1 update Both sd cards reformatted to FAT 32X Schedule: 0000-2400 hrs Factory default: R: Sample Rate – 48 R: Gain – Medium AM1: A: 48 Hz DC blocking filter – Disabled F: Trigger Type None; Filter Type – None AM2: F: Trigger Type – Amplitude; Filter Type – None; Min Trigger duration 0.001 A: 48 Hz DC – Enabled RESULTS: White noise present both units AM1: White Noise less intense Suspect that the trigger type has no influence on the occurrence of white noise. Test 2 AM1: R: Sample Rate - 8; Gain – Low F: Trigger Type – None A: 48 Hz DC – Disabled AM2: R: Sample Rate – 8; Gain – High F: Trigger Type – None A: 48 Hz DC – Disabled RESULTS: White noise present AM2: White noise slightly more intense Test 3 AM1: R: Sample Rate – 48; Gain – Low AM2: R: Sample Rate – 384; Gain – Low RESULTS: White noise present Test 4 AM1 & AM2: R: Sample Rate –8; Gain – Low A: 48 Hz DC – Enabled RESULTS: White noise present, intensity very low, doesn’t seem to pick up sound unless really close to the units, for example the impact of rain. Test 5 AM1: R: Sample Rate – 8; Gain – Low A: 48 Hz DC – Disabled; Enable Low Gain – Enabled AM2: R: Sample Rate – 8; Gain – Low A: 48 Hz DC – Enabled; Enable Low Gain – Enabled RESULTS: White noise eliminated. Recording of birds chirping really faint. AM 1 play back of chirping more distinct and likely due to microphone orientation being more inline to source. Test 6: Attempt to improve recording clarity and volume of sound AM1: R: Sample Rate – 8; Gain – High A: 48 Hz DC – Disabled; Enable Low Gain – Enabled AM2: R: Sample Rate – 8; Gain – Low A: 48 Hz DC – Disabled; Enable Low Gain – Enabled RESULTS: TBD
