QRQ CW Tesla Coil with FERRITE CORE Transmit Antenna at 75Khz - sending CW at 75wpm - LIVE demo

Brief demo of using a TESLA COIL with a ferrite core, self resonant at @ 75Khz - sending QRQ CW at 75 wpm The tesla coil primary winding is about 7 turns, fed by a 10 watt audio amp both TX/RX use soundcard SDR's with soundcards operating at 192Khz sample rate using the RECRI KEYER SDR modules and CW KEYBOARD to modulate and demodulate at this LF frequency https://github.com/recri/keyer

Here is a SPECTRUM READOUT of the self resonant 75Khz frequency of the QRQ CW TRANSMIT TESLA COIL ANTENNA   (uses a NOISE GENERATOR to send white noise from 1hz to 96Khz)
