IAMBIC KEYER PROJECT
Build your own IAMBIC keyer within a few minutes


Here's my version of an IAMBIC morse keyer for homebrew/QRP projects.
The micro is available for less than 2 Euros from many suppliers.

Design goals:

- Sidetone
- IAMBIC-keying
- Transceiver PTT switching
- Variable Morse Speed 
- Small
- Easy to build


Hex-File for programming the micro (ZIP file): download

Important:
ATtiny2313 Fuses:
By default the micro's CKDIV8 fuse is checked.
Prior to program the micro uncheck the micro's CKDIV8 fuse to enable the internal 8 MHz clock generator otherwise the micro will run with wrong 1 MHz clock by factory default.
