- Easy Morse Code Keyer Circuit
- based on the famous Curtis family of morse keyer chips and has a proven record of dependability.
- Simple Electronic Keyer
- A simple keyer which can be built for as little as $6 with some junk box parts. Although this circuit is not a true iambic keyer, it is capable of producing perfectly sounding CW.
- Made your Iambic keyer
- This iambic keyer uses a PIC16C84 or PIC16F84 microcontroller to generate the dot/dash timing and key the transmitter.
- G4AXX Voice keyer Interface
- This voice-keyer-interface connects between a Yaesu FT1000MP and a PC's sound card & COM port. It can be used as a voice-keyer with Contest Voice Blaster and as a voice-keyer and CW-keyer with Writelog.
- CW keyer
- The PIC-MORSE is an electronic iambic keyer, integrating a generator of Morse code and a sidetone. It is built with a microcontroller PIC16C711. In French
- External Keypad for FT-817
- An external keypad for FT-817(ND), for the serious portable/field-day contester/operator. Homebrew it with the free firmware and public circuit diagram.
The circuit is very simple and takes power supply from the ACC port of the radio
