   The CW unit can be used with most of HF transceivers. 

The KIT consists of the following components:

- the documentation in English 

- High quality PCB 

This CW unit can be used with amateur transceivers "Rosa", "Klopik", "Sloboda" and others. CW unit consists of: automatic CW key, CW crystal oscillator and "self-check" function.

            The core of automatic CW key is the ATTiny13 microcontroller. It forms an output CW signal with a ratio 1:3, regulates the transfer speed in the wide range of speeds. The Potentiometer  R5 regulates the speed of transferring the signal.
