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:…

This video demonstrates an A/B comparison of transmitting morse code audio tones over the internet using a NINJAM SERVER, where the CW audio quality is usually poor, with lots of pops and clicks...however, if you use the original audio from the output of the NINJAM CLIENT, and divert it first to a software APPLICATION in order to regenerate the…

This video demo's how to create a TEXT TO MORSE CODE MIDI FILE - to use for training in QRQ CW COPY. REAPER is the main APP for playing the morse code midi file. This method allows you to choose the CW PITCH, the VOLUME, the SPEED, THE RISE and FALL TIMES of the CW EDGES.. Some more advantages of using a MIDI FILE instead of an audio file for QRQcw…

CWMaestro - A morse code cw sending keyboard program written for the DOS operating system decades ago...still working by using the DOSBOX program which has versions for windows, linux and mac. This keyboard software also has a logging program and adjustable cw timing settings, hot key creator, custom messages...etc...

CWMaestro is a…
