This is an experiment in using free VST PLUGINS to create a MIDI KEYED morse code sine wave oscillator(software). It is "keyed" by MIDI INPUT. You can also use this midi setup to regenerate morse code audio tones from another source. FLdigi is used in the video for this purpose. Using MIDI to key a software CPO, shows great promise, since the accuracy of midi input keying is far superior to using a SERIAL PORT for this kind of a setup, in regards to accurate timing. Even at extreme QRQ CW…Continue
This video demonstrates an advanced method for qrq training with MIXXX using FREE VST PLUGINS to regenerate the exact incoming cw audio tones and recreate them with a FREE software CPO called BIPPER, - filter the final audio product - for audiophile quality qrq cw morse code audio tones. As an example, an audio mp3 file was made using FABIAN's ebook2cw program and then loaded into MIXXX for playback. The unique features on MIXXX make it a versatile training tool for qrq cw training;…Continue

EhoCW has just released a new version which allows for multiple instances and the option of using WASAPI AUDIO. WASAPI AUDIO DRIVERS are almost as good as ASIO DRIVERS in regards to cw timing accuracy and low latency. Only EhoCW has the option to select WASAPI SOUND CARDS, no other software cw keyer was found that had this feature. Two instances of EhoCW are used and setup exactly the same to send iambic morse code to two different sound cards - one instance to…Continue

This video demonstrates how to bring up multiple instances of QsoNet's Dahdidah Cw Software Keyer using FABULATECH's VIRTUAL SERIAL PORT SPLITTER. Four separate instances of Dahdidah are used - to hook up a cw keyboard, paddles, bug, and straight key, all at the same time. Connections are made from your iambic paddle keyer output, cw keyboard keyer output, straight key and bug - to separate SERIAL PORT PINS : DCD, DSR, RI, CTS in order to send morse code on your…Continue

I recently finished building my HI-PER-MITE cw filter. I am very impressed at how well this filter performs It may be one of the best active cw bandpass filters I have every used. Here are my results from testing this awesome filter:
Here is a picture of my build…Continue
A simple test was setup to determine how much latency there was,
from the time you tap one of the paddle handles,
until you actually hear the sidetone from…
CWTERM was one of the top choices in qrq cw sending software during the DOS computer era.
DOS seemed to be able to take complete control over the serial port and therefore, the timing and accuracy
was very good when sending qrq cw to your…Continue

This video will demonstrate a free software setup to get rid of the audio distortion you hear when listening to any of the WEBSDR websites, since they have bandwidth limits and have to use low sample rates for their audio streaming.
This same method will also help to clean up your own RIGs audio, or even an mp3 or wave file of some morse code recording.
