qrq

High-speed Morse trainer that pushes your callsign copy to its limit

What it does

Sends a callsign, you type what you heard, and it speeds up when you are right and slows down when you are not. Scoring is weighted so a correct copy at high speed is worth more than several at low speed, and the result goes into a local high-score table. It is a Linux equivalent of DL4MM's Rufz.

Why you would want it

Contest and pileup work is callsign copy under time pressure, which is a different skill from copying prose, and no amount of ebook practice develops it. This is the drill that does. It also finds your actual ceiling rather than the one you assume you have.

Before it will work

Working sound output. It generates its own tone, so no radio or interface is involved.

How it installs

  • apt: qrq

Known problems

It plays a callsign exactly once — that is the point, and it is demoralising for the first few sessions. Start with the speed floor well below where you think you are. The bundled callsign list is drawn from real contest logs, so it is heavy on the prefixes that actually appear on the air rather than on an even spread.

Keeping it current

  • probe: apt policy
  • strategy: apt_upgrade
