Could you assist me please a schematic maybe. Using a gravity wave detector concept. The gravity wave detectors if you still like the details may become handy in the paranormal field as they are on the hodowanec gravity wave detector site but no printed circuits for them and just part of a circuit so ive built them added the amplifier myself and made the printed circuit myself and upgraded them myself and tested them myself and have notes.
This rf detector circuit is designed based on transistors and common electronic components.
In the previous circuit we have used a 2n4403 transistor to activate the buzzer but in this circuit we have used a pnp darlington transistor. Could you assist me please a schematic maybe. As the circuit is a wide band rf detector therefore it can be used for testing many other rf circuits projects you build. Sensitivity to about 12m.
