Electronic morse keyer

Picobug MB2343SMD

Burkhard John

Picobug is a little project for the homebrewer. You will get a simple to use but quite comfortable morse keyer. Picobug is one of the smallest electronic morsekeyers of the world. Place it directly inside your homemade QRP-transceiver. The system is based on an Atmel AT90S2343 AVR-microcontroller in SMD-package.

Properties

  • The electronic generates exact dots and dashes with a relation 1:3 to form characters in morse code.
  • You can use a memory for dot and for dash.
  • You can use a single paddle or a squeeze keyer.
  • The speed can be adjusted freely from very slow to really fast.
  • The memory for text can save about 100 characters, enough space for a longer CQ.
  • The "Tune"-button helps to tune your transmitter.
