  3. T6 -- Good Operating Practices[3 Exam Questions -- 3 Groups]T8 – Good Engineering Practices [6 Exam Questions – 6 Groups] • T6A Calling another station; Calling CQ; Typical amateur service radio contacts; Courtesy and respect for others; Popular Q-signals; Signal reception reports; Phonetic alphabet for voice operations. • T6B Occupied bandwidth for emission types; Mandated and voluntary band plans; CW operation. • T6C TVI and RFI reduction and elimination, Band/Low/High pass filter, Out of band harmonic Signals, Spurious Emissions, Telephone Interference, Shielding, Receiver Overload. • T8A Basic amateur station apparatus: Choice of apparatus for desired communications; Setting up a station: construction and modifying amateur station apparatus; Station layout for CW, SSB, FM and Packet and other popular modes.

  4. Basic Voice (Phone) Communication Rules • Be polite • Do not interrupt other • Do not hog the channel • Listen before you talk • If someone else is using the frequency, let them have it, move to somewhere else. • Keep it simple • Speak Clearly • Do not rush it • Use Term people understand • Use the ITU Phonetic Alphabet to spell thing out • Use Common Abbreviations and TLA (Three Letter Acronyms) • Use the right side and for voice SSB • >14MHz - Use Upper Side Band

  5. ITU Phonetic Alphabet Agreed upon words to represent the letters of the “roman alphabet”. The boldfaced syllables are emphasized. The pronunciations shown in this table were designed for those who speak any of the international languages. The pronunciations given for “Oscar”, “Papa” and “Victor” may seem awkward to English-speaking people in the US.

  6. Common Abbreviation You need to know • CQ – Call Any Station • RST – Readability, Signal Strength, Tone • QSO – A communication • QSL – Acknowledge Reception • DX – Distance, foreign country • 73 - Best Regards • DE – From, this is • PTT – Push To Talk • VOX – Voice Activated Switch (x)

  7. Starting a Conversation (QSO) • Open Call – I will talk to anybody (CQ) • Listen • Check – Is this frequency in use? This is KD7PSV • Place the call • CQ CQ calling CQ. This is KD7PSV, Kilo Delta Seven Papa Sierra Victor, KD7PSV calling CQ and standing by. • To Answer • KD7PSV, this is N7SS, November 7 Sierra Sierra, N7SS over • Direct Call – I know who I want to talk to • Listen • Check – Is this frequency in use? This is KD7PSV • Place the call • KD7PSV calling N7SS, Kilo Delta Seven Papa Sierra Victor calling November Seven Sierra Sierra, KD7PSV calling N7SS • Answering a call • KD7PSV this is N7SS, over • Ending the Conversation • This is KD7PSV clear • This is N7SS clear

  8. Some HAMScollectQSL Cards

  9. The RST System

  10. Amateur Q Signals

  11. CW – 5-10Hz Phone/ Voice SSB - 2-3KHz AM – 4-6KHz FM – 10-20KHz Digital PSK31 – 31 Hz RTTY – 500 Hz Slow Scan TV – 3KHz Fast Scan TV – 6Mhz Common required Bandwidth

  12. S - Meters The S - meter gives a relative signal strength reading of a received signal. (Scale 0-9) No manufacturer claims their S - meters are calibrated.

  13. High Pass Frequency Low Pass, High Pass Filters Low Pass Frequency

  14. Band Pass Low Frequency High Frequency Band Pass Filter

  15. Determine the two bands that are interfering, and draw a line between them Determine which band to keep, or equipment to attach Left low, Right high Figuring out which filter you may need HF TV
