Hi John, Unfortunately I don't have time at the moment to build one of these, but they are quite easy to make. In essence, they are 2x high ohm coils, with a germanium diode in between. 1 coil will connect with it's inner wire end to the diode, the other coil will connect with its outer wire to the other end of the diode. If I remember right, the 2 spare ends then connect together and the output is across the diode, which can then go to say a PC's mic input on a soundcard. Audacity is good then for boosting the sound level and indeed any sound output can be listened to in real-time.
