The following DX Code of Conduct was developed by amateur radio operators and is promoted by the International Amateur Radio Union (IARU) as a global set of principles for on-air behavior when attempting to make DX (foreign country) contacts.
1) I will listen, and listen, and then listen again before calling.
2) I will only call, if I can copy the DX station properly.
3) I will not trust the DX cluster and will be sure of the DX station’s call sign before calling.
4) I will not interfere with the DX station nor anyone calling and will never tune up on the DX frequency or in the QSX slot.
5) I will wait for the DX station to end a contact before I call.
6) I will always send my full call sign.
7) I will call and then listen for a reasonable interval. I will not call continuously.
8) I will not transmit when the DX operator calls another call sign, not mine.
9) I will not transmit when the DX operator queries a call sign not like mine.
10) I will not transmit when the DX station requests geographic areas other than mine.
11) When the DX operator calls me, I will not repeat my call sign unless I think he has copied it incorrectly.
12) I will be thankful if and when I do make a contact.
13) I will respect my fellow hams and conduct myself so as to earn their respect.
