Using Linux software , a CW KEYER, iambic paddles, and a straight key are demo'd in this video...all morse code instruments are ready to send cw at any time in "near zero" low latency so there is no lag felt when keying any of these virtual Linux software morse code generators with your actual hardware iambic paddles, or straight key...

Using LINUX MINT 17.3 and some free DSP AUDIO LV2 Linux plugins...it is possible to get better cw keying on your Elecraft K3 and more versatility by bringing in the ability to use your ST KEY and IAMBIC PADDLES ... while preserving fast QSK full break in.
This is done by using AFCW A2 CW MODE and injecting a CW AUDIO TONE into the…Continue
This video demo's a Raspberry Pi being setup as a high performance morse code cw keyboard that keys a rig with just the analogue audio output sound card of the pi...where the pi's audio output goes to 2 individual audio derived cw keying circuits which in tandem key both the PTT first on the K3 and then the CW JACK on the…Continue

Brief demo of TWQRQ(by WA0EIR), running on a Raspberry PI2b
- qrq cw sent at 75 wpm, text is from w4bqf's famous article:
for more info and to request the latest beta version of TWQRQ please write…Continue
This video demos a - low cpu use - software setup - for sending and receiving morse code over Mumble Voice Chat on iCW using only the single analogue audio output of the Raspberry Pi the bcm2835 alsa sound card(output only)
NOTE: Raspbian Debian Jessie is the OS for this RazPi2b
for the lowest CPU use and…

DJ1YFK: FABIAN's famous high speed cw training program called "qrq" now has a windows version ! - see forum discussion below -
Fabian's qrq program is the best of the best when trying to train for copying qrq cw. Using the unique features of this program to train for copying "whole word sounds" is absolutely an essential part of a qrq cw training regime !
NOTE: see the article in the forum posted below for more information
Virtual Serial Port Kit -
create virtual serial ports connected via a virtual null-modem cable.
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.
I made a screen recording of a qso to demonstrate the serial interface between keyer / decoder of my ChipKit / PIC32 keyer. Both sides of the qso are displayed. The keyer switches the text color to…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
