I put the raudive detector circuit together tonight. Got a lot of weird sounds (not AC hum) when I held my DS-40 digital recorder lightly in my right hand. Sounded like ticking noise and squealing. Have to experiment more. Not sure of the size of the choke. Using an AM local oscillator coil in place of the 500 microhenry choke. The other parts are per the schematic. Tried the high impedance Realistic mic but I think the output is too low or the mic is bad. The mic is only 46 years old! Ha! Ha! Anyway, I have a high quality Marrantz cassette tape recorder with new batteries in it and using a sony external mic. So, I'm hunting for EVPs again! I have about six good EVPs recorded to date. Two using the Marrantz and the other four using my Logitech webcam mic with the Goldwave audio processor program.
