A gathering place for QRQ ops world wide to share information and experience in pursuing QRQ cw
ALL TIME = USA CENTRAL TIME
daily on 7018 4 pm
NOTE: if you have a QRQcw NET or know of one, please tell us about it, and we will post it here
brief test to see how well the EAC3 CODEC can reconstruct the ON /OFF cw element framework of Morse Code from a CW KEYER sending CW at "0" hz
NOTE: test starts out at QRQ speeds, then CW speed goes down to 20wpm, gradually back up again and over 100 wpm, then back down, to give an idea of how this experimental Morse…Continue

brief demo of having the AD5DZ CW Keyboard send a text file at 71wpm and then adjusting the KB's many settings to fine tune how the CW sounds for best COPY BY EAR during a QRQ CW training session

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.
Hello all,As a fun project I was writing a CW player for my Iphone over Christmas. A text file is converted to MIDI, MIDI is played out as audio on the Iphone. I am using Apple's MIDI player…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
