Hi Arnie, There is a lot of information on the Pro Antennas website in the what's new blog section: www.proantennas.co.uk/blog I am not quite finished with the code yet but will publish the sketches when it is ready - don't hold your breath, it has taken me 9 months to get this far! I don't think I have published component values on the schematics either but I can do that shortly. If you would like these in the current state, ahead of publication, contact me via the website and I will send them to you as is. Kind regards, Tony
@@proantennas Thanks! Great work so far. Yours is the first sketch I have seen that uses an adaptable Goertzel frequency to decode CW. The other sketches that use the Goertzel algorithm that I have seen all use a fixed audio frequency for decoding.
@@arniep740 Hi Arnie, Yes, that was the main challenge - finding a way to decide which audio frequency to focus on and then adapting the Goertzel calculations without creating floating point calculations that take far too long to process. With refinement, I'm hoping it will match the better PC based solutions but using a much lower powered processor.
Will you be sharing schematics and arduino sketches for this?
Tnx de Arnie W8DU
