Technician License Course Chapter 8 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 properating order. • No one owns a frequency; be a good neighbor and share. • Yield to special operations and special circumstances.

Types of Control Local. – The control operator directly makes adjustments to the transmitter. Remote. – The control operator can manipulate the transmitter controls from a distance Automatic. – Equipment and procedures allow some stations ( repeaters and beacons ) to operate without the control operator being physically being present at the control point. • “The control point is the location where the control operator function occurs. ”

Automatic or Remote Control • AUTOMATIC CONTROL • Some stations, repeaters and beacons, operate without the control operator physically present at the control point. • These stations must still comply with control operator stipulations. • REMOTE CONTROL • The control operator makes adjustments to the station from a location other than the transmitter location.

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. • There also some limited additional exceptions.

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. – Encryption is permitted to control satellites or model craft.

No Broadcasting • Broadcasting is sending one-way transmissions with no expectation of getting a response. – News – Music • Accepted one-way transmissions: – Transmissions of Morse code practice. – Ham radio related bulletins. – Re-transmission of shuttle communications ( with OK from NASA ).

Special Circumstances • Ham communication is generally intended for hams. • For example communications between hams and military stations may be permitted during an Armed Forces Day Communications Test. • Special commemorative events may also qualify as special circumstances.

Special Circumstances • Emergencies and critical situations create special circumstances. • If amateur radio is the only way to transmit critical information during an emergency to broadcasters so that they can warn the public about the emergency, this is permitted, despite the normal prohibition on using amateur radio for news gathering. • The normal rules return when the situation returns to normal.

Which of the following meets the FCC definition of harmful interference? (T 1 A 04) • A. Radio transmissions that annoy users of a repeater • B. Unwanted radio transmissions that cause costly harm to a radio station apparatus • C.

What should you do if you receive a report that your station’s transmissions are causing splatter or interference on nearby frequencies? (T 2 B 07) • A. Increase transmit power • B.
