These pages are dedicated to my CW-Keyer project. If you'd like to build one, you'll find all the required informations you need. If finished, it can (will?) be looking like this:
Most prominent features of the keyer:
- WPM 0...99 via Speed settings
- Core tested for rock solid timing up to up to 150 WPM when keying from memory -- who needs that?
- Iambic Mode A
- Iambic Mode B
- CMOS SuperKeyer (Iambic B with different timing -- currently untested)
- Buttons (1 Command-Button, 8 Function/Memory-Buttons)
- On the fly ratio-change for aurora and meteo-scatter
- energy-saving-modes: sleep and auto-power-off
- immediate wake-up on any morse-key-action (less than 2µsec)
- easy usage
- small lightweight firmware
- written in C++ for easy maintenance
- relatively easy to extend
- hardware-compatible to K3NG's firmware, see http://blog.radioartisan.com/arduino-cw-keyer/
