virtually perfect CW NOTEs in spite of using the lowest possible OPUS AUDIO CODEC bitrate on Mumble "8Khz"

- uses the REVERSE IMAGE CW METHOD for injecting silence into an audio stream, representing each CW ELEMENT; breaking up the 150 hertz stream with silent cw element blocks by using a REAGATE…

using high Q, tuned, resonant VLF ferrite TX & RX VLF antennas(4.078Khz) a QRQ CW square wave into the resonant, tuned, high Q, TX antenna produces minimal harmonics...and even less of those harmonics survive by the time the same type of RX ferrite rod high Q, tuned, resonant, antenna removes even more of the…

working with 4Khz VLF ferrite rod TRANSMIT and RECEIVE antennas that are High Q & tuned to resonance(see previous 2 videos for the more info on the FERRITE ROD HIGH Q antennas being used for TX & RX on 4Khz VLF):…
