we are quite interested with this project..we tried it out but we aren't sure yet what to do next after the receiver coil was set up..we used irf transistors instead of stn..will the resistors(at the test point) alter the frequency of the series resonant tank circuit at the transmitter?where and how should we connect our oscilloscope to the LC circuit?anyway, thanks for the effort in answering my reply despite your sked.we are hopeful for your future replies.^_^
