CW trainer online for ham practice

Built for people who say “CW,” not only “Morse hobby.” Warm up copy in the trainer, send on the keyer, check speed on the WPM test, and keep Q-codes / prosigns one click away. Still not your exam session or logging software.

When to use

Pre-net warmups; rusty ticket holders; practice without firing up a separate desktop trainer; quick Q-code / prosign refresh before a practice QSO.

When not

Contest logging, spotters, and rig keying stay on your real station stack. Beginner map lives under for/learn if you’re starting from zero.

Assumptions

Defaults lean Char ~20 WPM with adjustable Farnsworth; sidetone locally generated. Browser keyer is timing practice, not a USB paddle driver.

Examples

Input

15 minutes copy at 20/12 Farnsworth

Result

Then 5 minutes keyer on your callsign

Input

Drill QTH / QRM / QSL as Morse after the glossary

Result

Meaning first, then sound

Input

Pre-net 10-minute listen + one WPM check

Result

Honest speed before you join a practice net

How it works

  1. Warm copy in the trainer (or listen for open drills).
  2. Send on the keyer — callsign and short phrases first.
  3. Check speed on the WPM test; skim Q-codes and prosigns as needed.

Trainer copy → keyer send → WPM check → Q-code / prosign reference

Gotchas

  • Browser keyer ≠ USB paddle into a radio.
  • On-air manners and band rules are your license’s job, not this site’s.
  • “CW trainer online” traffic is small but intent-rich — keep the tools deep, not the landing fluffy.
  • One web WPM score is not an exam pass.

Browser vs station

  • Browser keyer ≠ USB paddle into a radio.
  • On-air manners and band rules are your license’s job.
  • Use whatever you’ll actually open daily — LCWO, desktop, or this lab.

Beginners

Absolute zero? Start at for/learn so you don’t skip hearing letters.
