Summer 2020 WARNING!
Last time we faced a drop sample problem with some computers. It can be seen in spectrum analyzer as a higher level, or (with small FFT points quantity) - jumping up-down.
This phenomena occurs as on new as on old PC, without any correlation!
And is independent from the Windows type - we tested Win 7/32, Win 7/64 and Win 10/64 on different hardware.
We found solution, so we can continue to manufacture Olivine-2.
Solution is here. (firmware update process may not work under MacOS/Linux!)
