Looking back to Alex's message of 30 March 2018, were the acrylic cases ever made available, or are the waterproof membrane stickers used on these cases available?

Thanks Andy. I had a poor session when using my second moth in the acrylic case that came with the BCT pilot scheme. Thousands of 'Soprano Pips' that just were not there. Haven't experienced this with the original moth.

Andy: Not as much of an issue (as far as I know) but any idea about the smears at c. 18 kHz and c. 40 kHz as well? They seem to be intrinsic to the device as I've had them in recordings made 20 miles apart.

Thanks for getting back Andy. I'm using SanDisk Extreme 32GB. I tried it in a ziplock bag and without an enclosure. It seemed perhaps a bit worse in the bag. With the LED off it's still there but less noticeable. [And on 'default' the LED still flashes when configured 'off' (but not on 'custom').]

I had one moth and got another from the recent batch. There's what looks like a sharp click coming out in the recordings, most noticeable at about 56-60 kHz, and pulsing every 85 ms or so when using a sampling rate of 192 and every 42 ms approx. when the sampling rate is 384. The red LED seems to flash about every 85 ms on SR=192. Are the clicks and the flashes linked? I've tried various recording locations and it's not extraneous noise, and it happens on both devices though it is weaker on the first one. The clicks from the second device are a bit of a problem as the software I'm using seems to be interpreting some (lots) of them as Soprano Pipistrelles.
