Morse Code Practice Raspberry PI 4 Twitch LIVE stream - 25 wpm to 100 wpm: select speed by QUISK SDR

TEST sending i q stereo into TWITCH

using 16 CW keyboards from a Raspberry PI 4 that is sending CW from 25 wpm to 100 wpm in 5 wpm steps

from -16Khz to -2Khz and +2Khz to +16Khz (2Khz steps)

QUISK SDR…

QRQ CW PRACTICE using an iphone - uses realVNC, Raspberry PI4, Mixxx & SonoBus 'audio over ip' APP

Mixxx allows you to go back a word or two(or more) to play again, a word or phrase that you may not have copied fully Mixxx also allows you to adjust the SPEED of the QRQ CW COPY PRACTICE session - 'on the fly'

NOTE: to keep the pitch the same, no matter the MIXXX variable speed setting, ZAMGATE and a pure sine wave…

CW keying data attoWatt modulation of a 12Khz VLF RF carrier: ZamGate DECODER converts it back to CW

experimental CW KEYING DATA modulation of a 12Khz VLF RF carrier that uses attoWatt modulation to achieve its goal of sending CW through the VLF CARRIER with the embedded attoWatt CW Keying data on it...

RECEIVER

VLF RF signal, is sent to a ZamGate sidechain GATE APP, which is able to extract the CW…

experimental Morse Code CW Braille Encoder/Decoder: Micro Modulate CW Keying data onto a VLF Carrier

experimental setup to encode CW KEYING DATA that looks a bit like BRAILLE onto a 16Khz VLF RF carrier - basically micro-modulating the tiniest increase in the 16Khz VLF RF carrier's power output that is directly in line with the timing of the arriving CW ELEMENTs that encoded the CW "BRAILLE" onto the VLF RF carrier by the ZAMGATE CW BRAILLE…

encoding & encrypting text message QRQ CW Morse Code KEYING DATA onto & into a 60 hertz audio signal

the encoded QRQ CW DATA is inaudible & virtually undetectable all you hear is a low volume 60 hertz signal, until the ZAMGATE DECODER is used to extract & produce actual CW NOTEs from the embedded CW KEYING DATA attached to the 60 cycle hum signal stream..... this encoding/decoding method can be used LIVE or implanted in a "safe"…

THE MATRIX - Morse Code Version - 10 CW signals in one DATA STREAM - LIVE demo using LYSDR to decode

Experimental CW MODE - embedding CW ELEMENTs onto a VLF CARRIER by increasing the volume slightly of the VLF CARRIER per each CW ELEMENT, the process includes 5ms Rise/Fall times of the VLF CARRIER EMBED Process(uses ZamGate in sidechain mode)

a MORSE CODE keyer / keyboard APP sends its output to the TRIGGER PORT of a…

Experimental new Morse Code CW MODE - Pilot Tone with inaudible embedded CW Keying Data - LIVE demo

ZamGate provides the method to ENCODE and DECODE the very slight volume increase in the CW pilot tone volume sine wave carrier(AM MODULATION of a sort)

TRANSMITTER cw keyboard keys zamgate in sidechain mode to allow the slightest increase in volume upon each CW ELEMENT being sent to be added to the pilot tone…

Receiving QRQ CW over the SLF BAND: LIVE demo: 50 hertz CW sent at 50 wpm: RX converts 50hz to 780hz

SETUP an SLF CW TRANSMITTER is sending at 50 wpm using 50 hertz SLF RF going to a FERRITE ROD SLF CW TRANSMIT ANTENNA - powered by a cheap class D 30 watt audio amp with the FERRITE SLF CW TRANSMIT ANTENNA hooked up to the CLASS D audio amp's output

Another FERRITE ROD SLF CW RECEIVE ANTENNA is hooked up to the…
