  2. Going On the Air • Choosing an operating frequency • You should listen to determine if the frequency is busy when selecting a frequency on which to transmit. • Calling CQ • You indicate you are looking for any station with which to make contact by calling CQ followed by your callsign. • The meaning of the procedural signal "CQ" is: Calling any station. • The brief statement, simply saying your call sign, is often used in place of "CQ" to indicate that you are listening for calls on a repeater.

  3. Calling another station • If you know the station's call sign, say the station's call sign then identify your own station when calling another station on a repeater. • You should transmit the other station’s callsign followed by your callsign when responding to a call of CQ. • You should avoid using cute phrases or word combinations to identify your station because they are not easily understood by some operators. • You should use the International Telecommunication Union (ITU) phonetic alphabet when identifying your station because the words are internationally recognized substitutes for letters.

  4. Calling another station • If you know the station's call sign, say the station's call sign then identify your own station when calling another station on a repeater. • You should transmit the other station’s callsign followed by your callsign when responding to a call of CQ. • You should avoid using cute phrases or word combinations to identify your station because they are not easily understood by some operators. • You should use the International Telecommunication Union (ITU) phonetic alphabet when identifying your station because the words are internationally recognized substitutes for letters.

  5. ITU Phonetic Alphabet

  6. Test transmissions • An illegal unidentified transmission describes a brief test transmission that does not include any station identification. • An amateur must properly identify the station when making a transmission to test equipment or antennas. • Station identification is required at least every ten minutes and at the end of every transmission.

  7. Use of minimum power • An amateur must use the minimum transmitter power necessary to carry out the desired communication. • This is the rule for: • Repeaters • Simplex • HF

  8. Band plans • A band plan is a voluntary guideline, beyond the divisions established by the FCC for using different operating modes within an amateur band. • Band Plans are voluntary guidelines for efficient use of the radio spectrum. • The amateur community developed the band plans used by amateur radio operators.

  9. A Band Plan is a voluntary guideline for using different operating modes within an amateur band. • 50.000-50.100: CW - No voice modes allowed per FCC section §97.305 • 50.060-50.080: CW/Beacon Subband • 50.100-50.300: Phone (SSB), etc. (no FM voice) • 50.100-50.125: DX Window • 50.300-50.600: All modes (simplex)50.600-50.800: Digital modes (e.g. Packet)50.800-51.000: Radio Control (R/C)51.000-51.100: "Pacific DX window" (SSB/CW)51.120-51.480: 6 Meter FM Repeater Inputs (areas w/500 KHz split)51.500-51.600: Simplex FM, 6 channels: 51.500, 51.520, 51.540, 51.560, 51.580, and 51.60051.620-51.980: 6 Meter FM Repeater Outputs (areas w/500 KHz split)52.000-52.480: 6 Meter FM Repeater Inputs (for 500 KHz and 1 MHz split) • Note: 52.525, 52.400, 52.040, and 52.020 are widely used for simplex operation with 52.525 being the "national simplex" frequency. • 52.500-52.980: 6 Meter FM Repeater Outputs53.000-53.480: 6 Meter FM Repeater Inputs and Repeater Outputs53.500-53.980: 6 Meter FM Repeater Outputs

  10. Repeater coordination • The recognized frequency coordination body is in charge of the repeater frequency band plan in your local area. • The main purpose of repeater coordination is to reduce interference and promote proper use of spectrum.

  11. Mode restricted sub-bands • The 6-meter, 2-meter, and 1-1/4-meter bands available to Technician class licensees have mode restricted sub-bands. • The only emission mode that is permitted in the restricted sub-band at 50.0-50.1 MHz is CW. • The only emission mode that is permitted in the restricted sub-band at 144.0-144.1 MHz is CW. • The emission modes that are permitted in the restricted portion of the 1-1/4-meter band are CW and Data.

  12. Authorized frequencies (Technician) • The frequency, 52.525 MHz, is within the 6-meter band. • The frequency, 146.52 MHz, is within the 2-meter band • The frequency, 223.50 MHz is within the 1.25 meter band. • The frequency, 443.350 MHz, is within 70-centimeter band • The frequency, 1296 MHz, is within the 23 Centimeter band • (sorry, you need to memorize these frequencies)

  13. Accountability • The transmitting station is accountable if a repeater station inadvertently retransmits communications that violate FCC rules. • Obscene • Ciphers not permitted • Unidentified communications

  14. Courtesy and respect for others • The proper way to break into a conversation between two stations that are using the frequency is to say your call sign between their transmissions. • Proper repeater operating practice: • Monitor before transmitting and keep transmissions short • Identify legally • Use the minimum amount of transmitter power necessary All of these choices are correct

  15. Courtesy and respect for others (cont) • Before responding to another stations call, make sure you are operating on a permissible frequency for your license class. • No frequency will be assigned for the exclusive use of any station and neither has priority. This rule applies when two amateur stations want to use the same frequency. • If you hear a newly licensed operator that is having trouble with their station you should contact them and offer to help with the problem. • When circumstances are not specifically covered by FCC rules the general operating standard of good engineering and good amateur practices must be applied to amateur station operation.

  16. Sensitive subject areas • Amateur radio operators should avoid the use of racial or ethnic slurs when talking to other stations because it is offensive to some people and reflects a poor public image on all amateur radio operators. • These types of subjects are not prohibited communications while using amateur radio: • Political discussions • Jokes and stories • Religious preferences All of these choices are correct.

  17. Obscene and indecent language • Indecent and obscene language is prohibited in the Amateur Service. • Because it is offensive to some individuals • Because young children may intercept amateur communications with readily available receiving equipment • Because such language is specifically prohibited by FCC Rules All of these choices are correct • There is no official list of prohibited obscene and indecent words that should not be used in amateur radio.

  18. Interference to and from consumer devices • The owner of the television receiver is responsible for taking care of the interference if signals from your transmitter are causing front end overload in your neighbor's television receiver. • The major cause of telephone interference is the telephone was not equipped with adequate interference protection when manufactured. • A break in a cable television transmission line may result in TV interference when the amateur station is transmitting, or interference may occur to the amateur receiver. • Receiver front-end overload is the result of interference caused by strong signals from a nearby source.

  19. Interference to and from consumer devices (cont) • Receiver front-end overload is the result of interference caused by strong signals from a nearby source.

  20. Public relations • RACES and ARES have in common the fact that both organizations provide communications during emergencies. • FCC rules apply to your station when using amateur radio at the request of public service officials or at the scene of an emergency.

  21. Intentional and unintentional interference • You should check your transmitter for off frequency operation or spurious emissions if you receive a report that your transmissions are causing splatter or interference on nearby frequencies. • The proper course of action if you unintentionally interfere with another station is to properly identify your station and move to a different frequency.

  22. Intentional and unintentional interference (cont) • You may never deliberately interfere with another station's communications. • No station has exclusive use of any specific frequency when the FCC has not declared a communication emergency. • The best way to reduce on the air interference when testing your transmitter is to use a dummy load when testing.

  23. Listen first, before transmitting • Looking for any station…call CQ • CQ means: Calling any station • On repeater, call sign instead of CQ • Calling another station • Their call sign and then your call sign • On a repeater and answering a CQ • ITU phonetic alphabet for identifying your station; avoid cute phrases

  24. Testing transmissions require identification • Unidentified transmissions are illegal • Even a brief test • ID required every ten minutes and at end of every transmission • Special events ID same ten minutes applies in addition to once an hour your own callsign

  25. Mode restricted sub-bands • 6-meter … CW • 2-meter … CW • 1-1/4 meter CW and Data

  26. Courtesy and respect on the air • Break into a QSO, by giving your callsign • Proper repeater practices: • Monitor/listen first keeping transmissions short • Identify legally • Use minimum transmitter power necessary All of these answers are correct

  27. Operate within limits of your license • No station has exclusive use of a frequency • Hear a new operator having trouble, offer to help • Not covered by rules: • General operating standard of good engineering • Good amateur practices (Must be applied to amateur station operation)

  28. Avoid use of racial or ethnic slurs • Offensive • Reflects poor public image • Subjects not prohibited: • Political discussions • Jokes and stories • Religious preferences All of these answers are correct

  29. Obscene language is prohibited • Because it’s offensive to some • Because young children may hear • Language specifically prohibited by Rules All of these choices are correct • No official list of prohibited words

  30. Front end overload responsibility is with the owner of the TV • Major cause of phone interference • Not properly equipped when manufactured • Cable TV cable break can cause • TV interference • Amateur receiver interference • Front-end overload is result of strong signals from nearby source

  31. RACES and ARES • Both provide communications during emergencies • F.C.C. rules apply to your station when using amateur radio at request of: • Public service officials • At scene of an emergency

  32. Splatter or interference reports from nearby frequencies • Check frequency • Spurious emissions • Unintentionally interfere: • ID properly • Move to a different frequency

  33. Deliberate interference … N E V E R • No declared communications emergency • No station has exclusive use of a frequency • Reduce on air interference • Test transmitter with a dummy load
