SIDECHAIN GATE MONO

and

OSCILLATOR MONO

IN sidechain mode, the gate will not let the OSCILLATOR MONO SINE WAVE pass through its upper port

however, when keyed by another CW…

RE: ENB-CW please see this playlist here for more info on this new CW MODE: http://www.youtube.com/playlist?list=PLfFan4sDonOf2O3s6PKh4fnDhEXrRaBut…

QRQ CW TRANSMITTER & RECEIVER are both using HIGH Q resonant systems on their Ferrite Loopstick ANTENNAs

PROBLEM - HIGH Q will cause ringing and MUSH on the RECEIVE signal

SOLUTION - use a GATE between 2 CW AUDIO BANDPASS filters

this video is a follow up video form the 1st one here:

brief demo of sending QRQ CW via ULTRASONIC EMF using TWIN FERRITE BOBBIN CORE INDUCTOR COILs as the Ultrasonic EMF Emitters

testing out a LARGER FERRITE CORE(loopstick)TRANSMIT ANTENNA fed by a 10 watt CLASS D audio amp transmitting an Extreme Narrow Band CW(ENBcw) ELF 738hz SIGNAL OUTPUT

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 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…

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…

Gstreamer provides the TCP/ip audio over ip streams to and from the RIG's connected interfaced Pi2b and the remote OP's PC https://gstreamer.freedesktop.org/download/ here are the scripts used on the PI2B, the laptop's scripts would be the same with the…

using different configurations of PVC PIPE(2 INCH Diam) to create a device that will be resonant, increase volume & the sound stage area, and just sit on top of one small speaker, (a radio shack communications speaker)

experimental BiPolar Tesla Coil with a large massive ferrite core, that resonates at 30Khz, to act as a CW transmitter antenna...

CW is sent from a CW KEYBOARD that can send directly at 30Khz, goes out of a sound card that has a sample rate of at least 96Khz...the 30Khz CW output goes to the audio input of a cheap class D…
