Notes on the T3 section
- Operating practices
When getting on the air, listen first to see if the frequency you're on is being used
No one "owns" a particular frequency; all hams share them
CQ, followed by your call sign, is used to look for a contact (CQ = calling any station)
When answering a CQ, send the other's station's call sign, then yours (be sure you are on a frequency you're allowed to
To interrupt an on-the-air conversation, say your call sign between transmissions
Always use the minimum power needed to communicate
On a repeater, procedures are a bit different:
- to interrupt a conversation (a QSO), say the other person's call sign, then yours
- instead of calling CQ, you just say your call sign to look for someone to talk to
- when using a repeater, listen before transmitting; ID legally; use minimal power
Test transmissions - to make sure you radio is working ok
- you must still ID
Phonetic Alphabet - used to spell out words
- standard phonetics are used; avoid making up your own or using "cute" ones to avoid confusing
other hams, especially foreign hams
-standard phonetic alphabet:
Alpha ... Golf ... Mike ... Sierra ... Yankee ...
Bravo ... Hotel ... November ... Tango ... Zulu ...
Charlie ... India ... Oscar ... Uniform ...
Delta ... Juliet ... Papa ... Victor ...
Echo ... Kilo ... Quebec ... Whiskey ...
Foxtrot ... Lima ... Romeo ... X-ray ...
Band plan - a voluntary guideline to use certain operating modes in certain parts of bands
- developed by hams and ham organizations
- among the bands used by Techs, there are mode-restricted sub-bands on the 6 meter, 2 meter, and 1.25 meter bands
on 6 m: 50.0 - 50.1 is for CW (Morse code) only
on 2 m: 144.0 - 144.1 is for CW only
Repeater coordination - repeaters operate on certain frequencies; they are assigned these frequencies by repeater
coordinators to make sure they don't interfere with one another and to use the available space on the radio bands
(available "spectrum") efficiently
- repeater frequency coordinator: person in charge of repeater frequency band plan
If a repeater is used to send an illegal transmission, the person sending the transmission is responsible (not the person or
club that owns the repeater)
Indecent and obscene language is prohibited…
…since it offends some people
…since young children might be listening
…since it violates FCC rules; there is no official list, use discretion
Racial & ethnic slurs offend people and reflect poorly on all hams; don't use them.
Political discussions, jokes and stories, religious discussions okay, but be careful not to offend when discussing sensitive
topics. Always operate using good engineering and amateur practices.
If you hear a new ham having trouble on the air, offer to help
If you are told you are causing interference, check your transmitter to make sure it is working properly (not emitting
spurious signals or transmitting off-frequency)
Front end overload - when a strong nearby signal overloads a nearby TV or radio (when your neighbor hears your
radio signal through his TV or radio)
- if your radio is working okay, the owner of the TV is responsible
- a lot of modern electronics equipment (telephones, TVs, etc) is not built with adequate
If you interfere with another ham on the air, ID your station and move to another frequency
Sometimes if TV cable is broken, it can make the TV pick up interference or cause interference to your ham radio
Use a dummy load to test your radio without actually sending out a signal ( a dummy load is a device that takes the radio
waves you're transmitting and changes them to heat)
