CW trainer online for ham practice

Warm up copy in the trainer, send on the keyer, check speed on the WPM test, and keep Q-codes / prosigns one click away. Built for CW practice in the browser — logging and exams stay on your station stack.

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.

Better elsewhere

Contest logging, spotters, and rig keying stay on your station stack. Starting from zero? Use for/learn.

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.
  • A single web WPM score does not replace an exam.

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.
