Each operator should study the recommended operation guidelines below:
Amateur Radio Do's
Always be polite regardless of the circumstances. If not, avoid transmitting.
Set a good example especially for short wave listeners who may be thinking about becoming a ham.
Be a good listener. It will help you better organize your thoughts before transmitting.
Reply to a CQ, or call CQ yourself. It helps keep alive the magic of ham radio.
Speak clearly and slowly, especially when giving your call sign to someone you have never worked before.
Promote friendship and goodwill to DX contacts. Look for ways to get to know each other rather than simply exchanging signal reports and 73s!
Try to keep track of everyone in the QSO. Hopefully someone has assumed the role of "traffic director" to make sure everyone has a chance to contribute to the discussion. If not, don't hesitate to do it yourself.
Make it clear at the end of each transmission which station is expected to transmit next. Try to do this even when operating VOX.
Operate on frequencies that are in whole KHz (e.g. 7.070 Khz). This alleviates ambiguity and makes it easier for everyone to be on the same frequency.
Openly praise other hams when you observe them doing something that you feel is especially deserving. e.g., helping demonstrate ham radio to a group of scouts.
Always be ready to quickly and calmly respond to emergency situations. Rehearse what you would do if presented with various scenarios.
Make a point to try other bands than just 40 and 6 meters. Good operating practices are especially prevalent on these bands.
Look for opportunities to "Elmer" newly licensed hams when you hear them on the HF bands. Welcome them, solicit their questions and give them pointers on good operating practices.
Remember that no one country can proclaim to be the leader of the Amateur Radio world. Likewise, no one country's foreign policy is any more right or wrong than that of another country.
Develop good operating practices. You will be doing your part in helping insure the continuance of our long and proud tradition of self-regulation.
Amateur Radio Don'ts
Don't act like some sort of Broadcast Radio station. Your fellow Amateurs will most likely not appreciate such a blatant display of personal ego.
Don't acknowledge the presence of deliberate interference. After all, that's most likely the overall objective of the person doing the interfering.
Don't be excessively long winded especially when in a round-table discussion and during times when band conditions are changing.
Don't just talk about ham radio. Most hams have many more interests.
Don't operate when you are in a bad mood. You will be that much more vulnerable to losing your temper.
Don't overuse Q-codes and other ham jargon on the phone bands.
Don't claim or homestead any particular frequency for nets, schedules, etc. If your designated frequency is already in use, simply move up or down as necessary.
Don't transmit before first determining that the frequency is clear. This includes transmitting within 3Khz of other known QSOs.
Don't break into an ongoing QSO unless you can hear the majority of the participants.
Don't use the word "break" or "QSK" when wanting to join an on-going QSO. Simply give your call sign between transmissions and reserve the use of the word "break" for more urgent situations.
Don't join an ongoing QSO unless you have something to contribute to the discussion. It is especially rude to interrupt other hams with a request for audio checks, signal reports, etc.
Don't ignore someone new to a round table QSO. We should all do our part to make everyone feel welcome. Avoid making the discussion appear exclusive to your particular circle of friends.
Don't test your transmitter over the air. It is far better to use a dummy load.
Don't cough, sneeze or clear your throat into your microphone.
Don't become a "Band Policeman" quick to tell others what you feel they are doing wrong. In instances where it may be called for, always be polite and constructive.
Don't turn up your microphone gain or resort to excessive speech processing in order to be heard. Such practices will most likely result in diminished audio quality and increased likelihood of interference to nearby QSOs.
Don't operate in any fashion that is not in keeping with good amateur practice. Be certain to always comply with the provisions of Part 97 of the rules.
Don't knowingly interfere with an ongoing QSO just because you are working DX, especially split frequency.
Don't say that the frequency "is not" in use when you hear someone inquire. Refrain from responding at all unless you know for certain that the frequency or one nearby "is" in use.
Don't ridicule other hams or express any negative views of the overall state of Amateur Radio. If you don't have something positive and constructive to say, avoid saying anything at all.
