Chinese Whispers Championship


  • Communicators Without Borders

Chinese Whispers Championship (CWC) Contest is a weekly event taking place for one hour on Saturday on 40m CW and one hour on Sunday on 20m CW. Each month the totals for that month determine the CW Championship winners.

While most amateur radio contests used to evolve around stamina although these days they often evolve around button pushing and automation, the Chinese Whispers Championship measures accuracy and skill in the sending, receiving and relay of messages.

Points are scored for each message sent or received in a certain format (called a QTC) with penalties for inaccuracies or omissions.

Participation Rules

Ahead of the CWC prepare yourself by downloading and printing off the IARU Message Form.

You will use one form for each message (QTC) that you receive, and also for the first message that you will send which is the one that you will create. Decide who you will address this message to, it should be an amateur radio callsign, and ideally one that you think may be taking part in the CWC although it could be any radio amateur in the world.

Fill out the first QTC, and make up the Message Text which must be 25 words or less. Signature is optional. Below is an example:


Important things to note: you start your own messages from NR 1 and work your way up, each month, or each year, you can reset and start again from NR 1. C means it is a Contest message and not a real one that needs to be delivered. W11 means there are 11 words including the TO address (IK6IJF in this example) and the signature (LOU in this example). Z is the UTC time. ADELAIDE is the location of VK5EEE, put your city or town there.

At the CWC activity time (see below) you can start to call CQ CWC or look for those calling CWC. Send your QTC and earn 10 points, the other station will earn 10 points for receiving it correctly (see later below). Afterwards the other station can send you his/her QTC and you will earn an additional 10 points if you receive it correctly (see later below for details of points system).

Note that you only send your original QTC on the FIRST contact, after this you will always send the LAST RECEIVED QTC unless you had to abandon receiving it.

When exchanging QTC you should seek clarifications for any parts that you are unsure of becuase accuracy will earn more points and any errors are picked up by the CWC Committee after the end of the CWC and points are deducted for errors.

After completing your first contact, during which you are only allowed to send and receive ONE QTC, you must contact any other station to send and/or receive a QTC before you can then work any previous station again. Stations can be worked as often as time allows during the hours of the CWC however, each time you must work a different station in between, so you cannot work the same station consecutively. During each contact you can receive and send one QTC each.

Remember to always send the last QTC you received from the previous station, on to the next station you contact.

There is one exception to this rule: if you have received one or more QTC that is for a particular station, and you are now in contact with that station, you can send them those QTC and earn additional bonus points (see below for bonus points), as well as the QTC you received from the previous station. In such cases you can send TWO or more QTC (the last one received, and those that you have received that are addressed to the station your are now in contact with).

For example, if you received the above example QTC which is addressed to IK6IJF and you are now in QSO with IK6IJF you can send it (and any others for IK6IJF) and also the last QTC you received from the previous station. This way you maximize your points. In all other cases you can only send ONE QTC, the last you received, if you don't have, or have already sent, messages addressed to that station.

Points and Bonus Points

Each QTC received earns you 10 points, each QTC sent earns you 10 points. At the end of CWC all the QTC must be sent in to the CWC Committee (see further below) and points will be deducted for errors in QTC received as follows: 1 point for each minor error of an incorrect character, 5 points for a missing word (thus a maximum of 5 points is deducted for a missing or wrong word), 3 points for an incorrect Word count where the W number does not match the word count (see above example).

20 additional bonus points are given for any QTC that is sent to the addressed station, but stations receiving QTC addressed to them are not awarded extra bonus points. 20 additional bonus points are given for QTC sent and received outside of your own IARU Region. Points are doubled for stations that testify they were operating QRP at 10W or less output to the antenna, or Mobile (at any power).

At the end of each month, all CWC participation logs and Message Forms should be sent by post or Email (scanned copies/images of the written forms sent and received or text versions thereof) and results are announced 3 months later.

For a QTC sent or received to be valid it MUST contain also the completed "sent to" or "received from" section including date, time, callsign sent to/from, and frequency band. If this information is missing the QTC will lose (additional) 5 points.
