I've been testing an optical link design that replaces a normal microphone. The link consists of a red LED coupled to the sound source (EVP Maker or Linear radio  sweep) and the resultant modulated light is picked up by a photomultiplier tube.  The output of the tube is recorded on a VHS VCR (analog). Here 's a couple examples from last nights session using EVP maker.

Example one: "Some people being taught, there's mentors feeling hope"
