SETUP: an UltraPico Keyer, keys a 555 TIMER CHIP..from the audio output of the 555, an audio cable is attached and goes to the input of a laptop's mic jack input...the 555 time chip sidetone is very rough sounding with lots of high pitched harmonics and key clicks...INSTEAD of trying to filter the 555's raspy tone, this video demo's using TRIGGER…Continue
SEREN - FULL MESH, P2P AUDIO, FULL DUPLEX, HIGH FIDELITY, with adjustable bit rate..mono or stereo....using the OPUS CODEC
- LIVE DEMO SETUP -
1st SEREN OPERATOR, will act as the Central SEREN NODE using a Raspberry Pi that is always "ON"...two more SEREN operators will connect to the PI's SEREN NODE and automatically be…Continue

GLAZE is a very simple p2p audio app for WINDOWS, MAC and LINUX that lets you easily create a voice chat room, call it whatever you like and you can have your fellow Morse Code OPS join you on GLAZE with just the name of the room. - no subscription required....no logins...no passwords...just the name of the room, and then type in any user name you…Continue

this video demo's 3 cw ops transmitting over MUMBLE, in the same channel, on iCW at the same time and yet on the receive side, each op's individual audio stream is able to be controlled using this experimental setup using all free software.
EXPERIMENTAL TEST SETUP
3 different cw ops are sending at different speeds and different pitches…

2 low bitrate codecs are compared for how well they sound transmitting CW AUDIO TONES over the internet(FLdigi)...and then how well they do when their original low bitrate cw audio is regenerated using all free software vst plugins
here is a snapshot comparing the original waveforms of the 2 low bitrate codecs:…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.

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
