Lesson Module 19: Operating Regulations:

Interference; Remote & Automatic Operation; Prohibited Transmissions

Interference

• QRN– Natural interference (thunderstorms).– Man-made (appliances and power lines).

• QRM– Interference from nearby signals.– Other hams or other users of the frequencies.

• Operators should avoid interfering with other users of the frequencies.

Interference

• Harmful– Interference that is disruptive but not intentional.

– Deal with it as best you can and help others avoid harmful interference.

• Willful– Intentionally causing interference.

– This becomes a legal and law enforcement issue.

– This is rare and there are procedures to deal with this (ARRL Official Observers can help).

Preventing Interference

• Use common sense and courtesy.

• Keep equipment in proper operating order.

• No one owns a frequency; be a good neighbor and share.

• Yield to special operations and special circumstances.

Which of the following meets the FCC definition of harmful interference? (T1A04)

• A. Radio transmissions that annoy users of a repeater

• B. Unwanted radio transmissions that cause costly harm to a radio station apparatus

• C. That which seriously degrades, obstructs, or repeatedly interrupts a radio communication service operating in accordance with the Radio Regulations

• D. Static from lightning storms

Prohibited Transmissions

• Unidentified transmissions .– (not giving your call sign)

• False or deceptive signals.– (using someone else’s call sign)

• False distress or emergency signals.– (fake calls for help)

• Obscene or indecent speech.– (up to interpretation)

• Music.

No Business Communications

• You cannot make a profit through the use of transmissions made via ham radio.

• Advertising ham radio gear is okay as long as it’s not your regular business

• Exception: teachers may use ham radio in their classrooms.

No Encrypted Transmissions

• Encryption involves encoding information for transmission that must be decoded upon reception to interpret the information.

• This is okay if:– Coding is open source.– Intention is not to hide the message or deceive.

No Broadcasting

• Broadcasting is sending one-way transmissions with no expectation of getting a response.– News

– Music

• Exceptions:– Code practice.

– Ham radio related bulletins.

– Re-transmission of shuttle communications.

Special Circumstances

• Ham communication is generally intended for hams.

• Emergencies and critical situations create special circumstances.

• Special commemorative events may qualify as special circumstances.
