webRTC usually comes stock with several audio processing engines in place .... like AGC, NOISE FILTERING, ECHO CANCELLATION which all of them will destroy how QRQ CW sounds over webRTC's OPUS AUDIO CODEC audo processing engines...
used in this example is webRTC from JITSI MEET:…

Brief demo of using this TRF RECEIVER circuit(LINKED BELOW) to monitor the RIG's CW TRANSMIT - RF NEAR field - of my RIG's antenna on 80 meters
setup to listen to your rig's CW, using the RIG's antenna's NEAR FIELD RF EM - picked up by a TRF receiver's FERRITE ROD antenna - BFO'd by a simple VFO circuit

demo of using a 2nd receiver, a simple TRF receiver, to adjust your RIG and your KEYBOARD settings, to make sure you are sending cw just like you want...create your own custom CW NOTE with its own type of raised cosine edge, its own weight, rise/fall time... etc.. by listening in real time to this TRF Receiver
TRF Transmitter monitor…Continue

Serial Port Splitter -
share dataflow of one serial port among several applications.
Network Serial Port Kit -
access remote serial devices over local network or the Internet.
USB over Network -
share and access USB devices over local network or the Internet.
NOTE: A special provision has been made available by FABULTECH to official ham radio operators. See this article for more details about this incredible offer:
Invite a friend(s) to join you at this link and have a morse code qso with them
All you have to do is produce a nice sidetone, and run an audio cable from it to the MIC INPUT or LINE INPUT of your soundcard.
When you click on this link it will ask your permission to use your MIC, say YES and start sending morse
Using Mumble( open source skype like voip program )and FLdigi to communicate morse code over the internet. LIVE RECORDING from 2009. [ Missouri to Michigan internet path ]
SETUP: using a virtual audio cable, we connect the output of FLDIGI to the input of MUMBLE. We both connect to a MUMBLE SERVER and instead of using MICROPHONES, we send morse code audio tones at high quality, high fidelity, and low latency, to each other. The audio is FULL DUPLEX and allows for good QSK response during the conversation for breaking in.
In order to properly exercise, the standard keyboard should be altered.I am using a belgian AZERTY keyboard with the QRQ Application. (OS is Ubuntu 18.04.1)In order to type numbers I need to access…Continue

This project began life a bit before Hjalmar posted his Arduino decoder project. I had barely begun to migrate my keyer software to the ChipKit PIC32 boards (Max32 and Uno32) at that time. I…Continue
