Practice realistic Morse code QSOs by ear against ham operators with distinct fists and speeds. Handle QSB, QRN, and LIDs, then grade your copy — type your reply or key an iambic paddle.
You operate: work the stations yourself. Just listen: sit back and copy a live QSO or run — no typing.
Hunter: chase activators — copy each call and exchange. Activator: call CQ and run your own pileup, pulling one call at a time.
1 = a single contact. More = a run, back-to-back.
On: call CQ, then pull a call out of each pileup — no exchange. Every correct pull raises the next pileup, so it's pure pull-a-call-out-of-the-jumble practice.
On: harder settings favor faster, sloppier, weaker fists. Off: any op, any level.

What did you copy?
Fill in what you got by ear — this is the real test. Blanks are fine; take your best guess if you were close.

Callsigns
Copy real-format ham callsigns by ear, then type what you heard. Callsigns are the hardest thing to copy on the air — random letters and digits, no context to lean on. US and DX prefixes, hundreds of thousands of combinations.

Abbreviations
Copy the CW shorthand you actually hear on the air — common abbreviations (TU, FB, UR, 73), Q-codes (QRZ, QSB, QSY), and prosigns (AR, SK, BT, sent run-together) — then type what you heard.

CW Reader
Paste text or upload a .txt chapter and copy it by ear. Farnsworth keeps characters at full speed but stretches the gaps — the easiest way to learn.
