The Danish Keyer


I have bulid a lot of keyers and all of them have been on the arduino platform.

This keyer are on a much faster board STM32F7-DISCOVERY. 

I have NEVER seen any other keyer which can decode without any problem what you send with speed 120 wpm ..THIS KEYER CAN !...and it goes higher ..much higher but i can not test that yet my self ;o)

The GUI is sliding so it mean that it is VERY easy to find all the settings and play with the settings when you do send.

Take a look on the youtube videos to see the GUI .

The project are what i think a great QRQ CW KEYER shall be.

So it mean that there will be some features i do not want to develop, because it is of no use when you do QRQ CW.

If you want to build this keyer you will find it VERY easy to make ...In fact you can be QRV under 1 hour from you unpack the board !

Below you will see a screendump off every screen.

Welcome screen

Main Screen where you can change speed, see what you send and see your timing of letterspace and wordspace

Here you can enable word and letterspace. enable decode on the main screen and set paddle reverse

The Dah to Dit ratio is green when set to 3.0 which are standard

Weight is green when 50%

Lazy dih and dah are when the keyer do look for dah or dit memory.

Here you can chose between the different keyermodes.

You can read about modes here

Chose between 2 paddles and enable the keying 2n2222 and tune buttom
