Copy real-format amateur radio callsigns by ear and type them back. US 1×2 through 2×3 formats plus a spread of DX prefixes — hundreds of thousands of combinations, and the toughest, most useful copy skill for contesting and DXing.
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.
