WISCO RADIO CW Trainer — learn Morse code (CW) the way hams actually use it, from your first two characters to a full on-air contact. Fully offline. No account, no network, no ads.
• Koch-method lessons — every character at full speed from lesson one, with Farnsworth spacing; a new character unlocks at 90% accuracy.
• A six-rung copy ladder — single characters, pairs, random groups, ham words, callsigns, and full QSO phrases.
• Sending practice with a built-in iambic paddle and straight-key decoder that shows exactly what your fist sends — including the HH "start over" prosign. Key on screen, with the keyboard, or with your own paddle or straight key through a USB adapter (VBand-compatible — the [ and ] keys).
• A QSO simulator with POTA, SOTA, IOTA, and ragchew contacts — on-air break-in fills, honest signal reports, and a 5-second "get ready" countdown before the code starts.
• Realistic band conditions — selectable receiver filtering (wide / CW 500 Hz / APF), QSB fading, and AGC.
• Reference guides on CW lingo, on-air procedure, and the history of the code.
