Tuned Bipoloar Tesla Coil with FERRITE CORE for a QRQ CW 16Khz VLF Band Transmit Antenna - LIVE DEMO

The tuning of the biploar tesla coil for 16Khz is quite sharp but dramatically increases the transmitter signal antenna output - the RX ferrite antenna is also tuned by a parallel cap (TRANSMITTER is a Linux laptop, RECEIVER Is a pi4) both antennas are using SOUND CARD SDR software modules from RECRI KEYER... to be able to send and receive at 16Khz on the VLF BAND
