About.
CW_Shark is a 32bit windows programme, designed to analyse, decode and encode morse code.
The programme can be used in four modes :-

1. Decode Only
This is the simplest option and only requires the audio from the radio to be fed to the soundcard of the PC. Not recommended but it will work using the microphone in a laptop to listen to the audio from an HF radio, (disable any noise reduction dsp on the laptop microphone).

2. Keyboard QSO
For transmission you need the output of the soundcard to feed the mic input of the radio. Additionally, PTT must be enabled either by VOX or preferable via the RTS of a COM port. If you have a working setup for digital modes such as FT8, then those settings should work for this programme.

3. Straight or Paddle Key QSO
To enable the paddle keyer, the ASIO4ALL driver must be installed for a 2nd soundcard, which will provide a low latency sidetone.

4. Straight or Paddle key practice
CW_Shark’s Tx monitor, allows hand sent morse to be decoded and analysed for timing accuracy. Further analysis is shown the ‘Key Tims’ form shows the timing of the paddle keys and the resultant CW.

Discussion.
CW_Shark is intended for personal morse code practice, in the hope that the programme is no longer needed. You can read about all functions of the programme here:-
