Bayesian Morse Decoder

 A Bayesian Morse Decoder

"To demonstrate the Bayesian decoding capability I tuned my KX3 on W1AW frequency 3.58105 Mhz at 8:00 PM EST today and let two identical FLDIGI copies of the same v3.21.75 software running from the same audio source. I have a SignaLink USB connected between KX3 and my ThinkPad laptop running Linux Mint OS. 

On Fig 1. below I have the legacy SOM decoder on the left side and the new Bayesian decoder on the right . The legacy decoder makes a lot of errors and CW bulletin is not really readable. On the right side I have enabled Bayesian decoder and you can actually read the bulletin, though the lack of proper word spaces make this still a bit difficult to read. In any case Bayesian decoder provides significant accuracy improvement with real life noisy CW signals."

Jot Script and Jot Touch 4 Review

This is by far the best review of the Jot Script Evernote Edition I've seen. He compares it with the Jot Touch 4.

Based on his comments, I think I will try the Jot Script - once I get a job.

On a related note, I ran into a guy using the Jot Touch 4 at a coffee shop and he showed me how he used it. It was clear he had mastered it - his handwriting on the iPad with the Jot Touch 4 was better than mine with pen and paper.
