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.

Operating practices T3A
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.

Operating practices T3A
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
Operating practices T3B
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
Operating practices T3B
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.
50.000-50.100: CW - No voice modes allowed per FCC section §97.305
50.060-50.080: CW/Beacon Subband50.100-50.300: Phone (SSB), etc. (no FM voice) 50.100-50.125: DX Window50.300-50.600: 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 51.600 51.620-51.980: 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 Outputs 53.000-53.480: 6 Meter FM Repeater Inputs and Repeater Outputs 53.500-53.980: 6 Meter FM Repeater Outputs
A Band Plan is a voluntary guideline for using different operating modes within an amateur band.
10
Operating practices T3B
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
Operating practices T3B
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
FCC Rules and Station Licensee Responsibilities T1C
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
Operating practices T3B
Accountability
• The transmitting station is accountable if a repeater station inadvertently retransmits communications that violate FCC rules.
Obscene Ciphers not permitted Unidentified communications
14
Operating practices T3C
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
Operating practices T3C
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 preferencesAll of these choices are correct.
Operating practices T3A
17
Operating practices T3A
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
Operating practices T3D
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
Operating practices T3D
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
Operating practices T3D
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
Operating practices T3D
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
Operating practices T3D
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
Take aways
• Listen first, before transmitting• Looking for any station…call CQ
