CwType verses YPLog - The qrq cw keyboard competition

Short competition (recorded live) between 2 very good qrq cw software keyboards - CwType verses YPLog -

sending a short text file from NASA NEWS, at 75 wpm. Timing is the main criteria since both keyboards are keying sineCW, a software code practice oscillator vst plugin, so they will "sound" the same for the most part, but how the cw is coded for precise morse [ element / spaces ] timing in software at qrq levels will be slightly different. YPLog has many adjustments…

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

iCW - 2012 - How to send morse code over the internet on WINDOWS 7 : THE BASIC SETUP


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.
