The project is a morse code keyboard and morse decoder.

It allows the user to send and receive morse code via a transceiver without any morse code knowledge.

It has an inbuilt keyboard for sending morse code, speed control, and a facility to send stored messages within a memory system.

Saved text can be sent by pressing a single key.

The decoder is assisted by using DSP techniques and uses the goertzel algorithm for tone detection. Using this method makes it highly resistant to noise.

The decoder automatically adjusts to any sending speed. It can decode very slow morse code and extremely fast morse code.

Included in the design is a high performance audio filter to reduce noise and to filter out nearby stations.

I hope to develop it further by making it smaller, and then possibly make it available in kit form.
