This video is a short demo of a first test trying to broadcast 5 FLdigi's sending at 5 different qrq speeds...where you can choose which FLdigi//speed you want to listen to - right from your browser listening to the TWITCH QRQcw CHANNEL.
a test to transmit and receive 5 individual channels of audio to AND from the TWITCH Streaming server -…Continue

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
