A Windows or Linux app for cw practice, for a user who has already learned the code. Practice from file input, or on screen text area. Selectable input filters (characters, ProSigns, Foreign chars); timing modes, speeds and tone, audio impairments; some headcopy features (IWR).

The web page: qsl.net/wa2nfn is essentially the app's Help file, it should tell all thats needed. Live play or create Wav files. Wave shaping should allow QRQ - I'd appreciate feedback if the speed limit is unreasonable or associated tone limit.

It's a single file binary, no changes to any PC configuration is necessary.
