Communicating with Other Hams

2. Phonetic Alphabet
When communicating by amateur radio, you will be exposed to (and will be using) a phonetic alphabet, or “phonetics”.

3. Phonetic Alphabet
The use of a standard phonetic alphabet avoids confusion.
Many English letters sound the same.
B,C, D, E, G, P, T, V, Z
F, S
M, N
Letters are pronounced differently in different languages.
In German, “Y” is pronounced “Upsilon”.

4. Phonetic Alphabet
A standard set of words, each word representing a letter of the alphabet.
First letter of the word is the letter that the word represents.
The FCC recommends the use of phonetics when identifying your station.
§97.119(b)(2)

5. Phonetic Alphabet
Preferred alphabet is the International Radiotelephony Spelling Alphabet.
ICAO Phonetic Alphabet.
ITU Phonetic Alphabet.
NATO Phonetic Alphabet.
Military Phonetic Alphabet.

7. Phonetic Alphabet
The use of country names or names of major cites is common.
e.g. – Denmark, Germany, Tokyo, Yokohama, etc.
Avoid non-standard or “cute” phonetics.
Especially for DX contacts.

8. Contact Basics Contact Contents. General Principles.
It is important to remember that communicating by radio is different than talking face-to-face.
You cannot see facial expressions.
You cannot see body language.
You cannot see hand gestures.
If CW or data, you cannot hear tone of voice.

9. Contact Basics Contact Contents. General Principles. Identify often.
Use phonetics.
Only one person can talk at a time.
Need way to indicate when you are finished & it is time for the other person to talk.
On CW or data, use the prosign “K”, “KN”, or “=” (BK).
On phone, use the proword “OVER”.
Speak clearly & distinctly.
Conditions may make speech difficult to understand.

10. Contact Basics Contact Contents. General Principles.
Procedural Signals.
Procedural signals are words, phrases, or special characters that have a specific meaning.
Used to increase the efficiency of communications.
On voice, procedural signals are words or phrases called “prowords”.
On CW & digital modes, procedural signals are special characters called “prosigns”.
1 or 2 characters.
If 2 characters, sent as a single character on CW.

11. Contact Basics Contact Contents. General Principles.
Procedural Signals.
Proword
Prosign
Meaning
OVER
K or KN
End of transmission & response is expected.
OUT SK
End of transmission & no response is expected. AR
End of message.
ROGER R
Message received.
WILCO
Message received & will comply.

12. Contact Basics Contact Contents. General Principles.
Q-signals or Q-code.
The letter “Q” followed by 2 additional letters.
Conveys an entire thought or sentence.
Adding a “?” changes it to a question.
Originally developed by commercial radio telegraphers for traffic handling.
Primarily intended for CW operations.
Commonly used on voice.
“Purists” say using Q-signals on voice is poor operating technique, but nearly everyone does it.

13. Contact Basics Contact Contents. General Principles. Q-signals.
Meaning
QRM
Interference (signals).
QSB
Your signals are fading.
QRN
Interference (noise).
QSL

18. Contact Basics Contact Contents. Using a Frequency.
Hams often tend to “hang out” on certain frequencies.
Local VHF/UHF repeater.
Favorite frequency for meeting friends.
NO amateur or group of amateurs has priority on the use of any frequency.
Not even established nets.
Exception: Actual emergency communications.

19. Contact Basics Contact Contents. Signal Reports.
Upon establishing contact, it is customary to tell the other operator how you are copying his signal.
Signal reports are sent as 2 or 3 numbers using the R-S-T system.
Signal reports for FM contacts are different & will be discussed when we talk about repeater contacts.

20. Contact Basics Contact Contents. Signal Reports. R-S-T system.
1st digit is Readability.
How well you can understand the signal on a scale of 1 to 5.
2nd digit is Strength.
Relative strength of the signal on a scale of 1 to 9.
3rd digit is Tone.
Purity of the signal on a scale of 1 to 9.
Not used for voice transmissions.

21. Contact Basics Contact Contents. Signal Reports. Readability (1-5).
1 = Unreadable.
2 = Barely readable, occasional word distinguishable.
3 = Readable with considerable difficulty.
4 = Readable with practically no difficulty.
5 = Perfectly readable.

22. Contact Basics Contact Contents. Signal Reports. Strength (1-9).
1 = Faint signals, barely perceptible.
2 = Very weak signals.
3 = Weak signals.
4 = Fair signals.
5 = Fairly good signals.
6 = Good signals.
7 = Moderately strong signals.
8 = Strong signals.
9 = Extremely strong signals.

23. Contact Basics Contact Contents. Signal Reports. Tone (1-9).
1 = 60-cycle AC or less, very rough & broad.
2 = Very rough AC, very harsh & broad.
3 = Rough AC tone, rectified but not filtered.
4 = Rough note, some trace of filtering.
5 = Filtered rectified AC but strongly ripple-modulated.
6 = Filtered tone, definite trace of ripple modulation.
7 = Near pure tone, trace of ripple modulation.
8 = Near perfect tone, slight trace of modulation.
9 = Perfect tone, no trace of ripple or modulation.

24. Contact Basics Contact Contents. Power Level.
Often you tell the other operator how much power you are running.
QRP operation is considered a transmitter output power of 5-10 watts or less.
QRO operation is considered a transmitter output power of 500 watts or more.
Remember the FCC rules say to always use the minimum power necessary to accomplish the desired communications.

25. Contact Basics Contact Contents. Locators.
You normally tell the other operator where you are located.
Method varies.
May be as simple as city & state or country.
May be latitude & longitude.
Maidenhead Locator System.
a.k.a. – “Maidenhead grid” or simply “grid”.
Especially popular for VHF/UHF/microwave operations.
Some HF contests contact value is determined by grid.

26. Contact Basics Contact Contents. Maidenhead Locators.
Adopted at a VHF/UHF conference in Maidenhead, England, in 1980.
Developed by Dr. John Morris, G4ANB.
The earth is divided into 18 rows of 18 fields.
A field is 10° latitude high by 20° longitude wide.
A field is denoted by a pair of upper-case letters (A-R, A-R).
Each field is divided into 100 squares.
A square is 1° latitude high by 2° longitude wide.
A square is denoted by a pair of numbers (0-9, 0-9).

27. Contact Basics Contact Contents. Maidenhead Locators.
Each square can be divided into 24 rows of 24 subsquares.
A subsquare is 2.5’ latitude high by 5’ longitude wide.
A subsquare is denoted by a pair of lower-case letters (a-x, a-x).
No 2 points in the same subsquare are farther than 7.5 miles apart.
Any point on the earth can be specified with good precision with just 6 characters.

28. Contact Basics Contact Contents. Maidenhead Locators. For example:
The locator for W1AW in Newington, CT, is:
FN31 or FN31pr.
The locator for this building is:
EM69 or EM69hk.

29. Contact Basics
Maidenhead Locators.

30. Contact Basics Contact Contents. Appropriate Topics.
Choose your topics carefully.
Avoid controversial or confrontational subjects.
e.g. – Politics & religion are generally discouraged.
Obscene & indecent language absolutely prohibited by regulation.
Remember, radio is a big party line!
Many people are listening.

31. Contact Basics Contact Contents. Signing Off.
Just like on telephone, it is rude to simply stop talking.
Customary to use one of the following:
73 – OM to OM contact.
88 – OM to YL contact.
33 – YL to YL contact.
Remember: You are required to identify your station when you sign off.
Other station’s call sign is optional.

32. Contact Basics Advising and Assisting.
Amateur radio operators have a long tradition of helping each other.
100 years ago there were no books or classes.
Hams taught themselves or learned from others.
The tradition continues.
More jargon: An “Elmer” is an amateur who helps and advises a new amateur, either in technical or procedural matters.

33. Contact Basics Advising and Assisting. Methods and Procedures.
Good operators are made, not born.
Listen & learn from others.
Ask questions.
Practice.
When giving advice:
Off the air, if possible.
Use kind & helpful tone.

34. Contact Basics Advising and Assisting. Methods and Procedures.
Most common mistakes are in technique.
Not listening or not listening long enough before transmitting.
Transmitting too soon or late.
Not familiar enough with radio.

35. Contact Basics Advising and Assisting. Radio and Antenna Checks.
Often you need an on-the-air check of how your station is working.
Best method is to call a friend & ask him to meet you on the air for a check.
Next choice is to call “CQ” and ask for a radio check.
Last resort is to break into an existing conversation & ask for a radio check.
Many will consider this rude, especially if you don’t know either operator.

36. Contact Basics Advising and Assisting. Radio and Antenna Checks.
When replying to a request for a radio check:
Be certain to give an accurate and detailed report.
Be certain to specifically address the suspected problem.
e.g. – If asked about audio distortion, don’t just give a RST report.

37. Contact Basics Advising and Assisting. Radio and Antenna Checks.
Frequently we want to compare different antennas.
Only sure way of doing this is with an on-the-air comparison by another station.
Same rules apply as when asking for a radio check.
Be certain to give an accurate signal report.

38. Contact Basics Advising and Assisting. Noting Violations.
The Amateur Radio Service is primarily self-policed.
The ARRL has established an Official Observer (OO) program to monitor our frequencies for potential rules violations, both technical and procedural.
If you hear a possible violation:
Diplomatically advise operator of problem.
DO NOT violate the rules yourself in order to make the notification.

It is a good idea to keep one anyway.
Record of contacts for awards and contests.
Record of propagation conditions.
Proof to the FCC whether you were operating at a particular time on a particular frequency or not.
Most hams log all HF & non-FM VHF/UHF contacts.
Maybe not log contacts with friends you frequently talk to.
