Exact Copy

Experimental tool

This is a new tool and is not finished.

Copy the information that has to be right: callsigns, reports, serial numbers, names, park and summit references, Field Day exchanges. One message at a time, typed (or written) as you hear it. Every message is marked character by character, and the history keeps what was sent beside what you copied.

Choose what to copy and the skill to practise, set your own speed, and press Play. The steps below show what the exercise does, and how to change it.

What to copy

Each message to copy is one of the switched on content types, chosen at random. The stations are generated the same way as in Ultimate QSO: callsigns follow real on-air activity, and a station’s name, town, section and summit belong to its country.

Band conditions

Make the Morse sound like it came off the air rather than out of a signal generator: atmospheric noise, fading, a receiver filter, and other operators on the band. The noise floor is calculated from the location, season and the time of day.

Each message

1: Listen - receive it

The message is sent once. With Type during on, you can type as it plays; off, the box stays shut until it has finished and the retain time is over. Off whenever Write is on.

2: Retain - hold it in your head

Time to hold it before recording it. A bare number is read as milliseconds. Add a unit to follow the Morse speed, e.g. “5dit”, “3fdit”, “1ws”.

How long after the Morse ends before you record it (e.g. “1000”, “5dit”, “3fdit”, “1ws”): copy it in your head, then type or write it. Only with Type during off. More CW sends more messages of the same kinds through that time, cut off when it ends; do not copy them.

3: Record - write it down

The time you have to answer in, after which the next message comes whether you have finished or not. A bare number is read as milliseconds. Add a unit to follow the Morse speed, e.g. “5dit”, “3fdit”, “1ws”.

Type after or Write: type what you copied and press Enter, or write it down and press Play. With Hold on the run waits for you; off, you have the time in the box (e.g. “1000”, “5dit”, “3fdit”, “1ws”) and the next message comes when it is up. Press ↑ or ? in the box to have it sent again. Writing, press X as soon as you know you have missed it.

4: Verify - check it against a second hearing

Verify sends the message a second time after you answer. Correct your copy if you need to and answer again.

5: Reveal - what was sent

A typed copy is marked by the tool. Reveal shows what was sent beside it, every wrong character marked, and Speech says it. With Write on, one or both is always on, since what was sent is what you mark your copy against.

6: Check - how you did

With Write on, the time you have to press X if you missed it; after it, the copy counts as copied. A bare number is read as milliseconds. Add a unit to follow the Morse speed, e.g. “5dit”, “3fdit”, “1ws”.

With Write on, you mark your own copy against what was shown or said: Hold until you press Play (copied) or X (missed), or have the time in the box (e.g. “1000”, “5dit”, “3fdit”, “1ws”) to press X. X works from the start of the message, so you can say you missed it as soon as you know. The Hit / miss bell then rings by the verdict, yours or the tool’s. Set the bells in the .

7: Speed - faster or slower

Faster by this percentage after a copy.
Slower by this percentage after a miss.

With Adapt on, the speed goes up by the first percentage after each message copied first time and down by the second after each miss, starting from your own speed. Your speed setting is not changed.

8: Wait - before the next message

Pause before the next message. A bare number is read as milliseconds. Add a unit to follow the Morse speed, e.g. “5dit”, “3fdit”, “1ws”.

Either Hold until you press Play, or pause for the time in the box (e.g. “1000”, “5dit”, “3fdit”, “1ws”).

End of run

E1: Length - when the run ends

How many messages a run has; 0 for no limit.

The run ends after this many messages (0 for no limit), or when the Timer runs out.

E2: Bell - the run is over

Bell rings when the run is over.

Notes

Each exercise has a link of its own, such as /labs/exact-copy/?preset=fieldDay. The exercises never set your speed, so the same link works for everyone at their own speed; add &wpm=18 to a link to set one.

An exact copy is every character right. A report or serial written as the number it stands for (599 for 5NN, 47 for 047) is right, and so is a park or summit reference without its hyphen.

Whole contacts are practised in Ultimate QSO. The callsign exercise with Adapt on is modelled on RufzXP.

There are . Press ? outside the answer box to list them.

    This browser cannot speak

    It has no speech synthesis, which is usual for a browser built into an app such as Facebook. Open this page in your usual browser to use speech.

    No text-to-speech voices found

    Check your browser and system speech synthesis settings.

    You are offline: only local voices are available.

    Speech Error

    Speech isn't working

    Some devices — especially Safari on iOS — need a direct tap before they will speak. Tap this to start speech:

    Tip: speech is much more reliable if you tap any button on the page before you press Play.

    If you are offline, choose a voice labelled "local" in the Speech controls.

    You can also turn speech off in the settings to continue without it. Avoid letting the browser go to the background or locking the device while it is speaking.

    Speech Error

    Speech did not start

    This may be because you are offline. If so:

    1. Open the controls
    2. Choose a voice that is labelled as "local"
    3. Try again

    Alternatively, you can disable speech in the settings to continue without it.
