HAM- An Elmer’s Guide
Posted
with permission from Garand_Shooter
A
long tradition, since the beginning of radio, has been for amateur to assist
newcomers in getting thier license. Nobody knows for sure why, but the one
teaching ahs always been referred to as an "Elmer".
That said,
I am creating this page to assist as a study aid. Study the material I post,
and take the practice tests at www.qrz.com
and you should pass your tech test with ease.
Side
note-
Morse code.
You will see below that in order to get privileges on HF freqs you must pass a
5wpm Morse code test. This is greatly reduced from what it was when I first go
licensed, when you had a 5, 13, and 20wpm test. 5wpm is easliy learnable.
To learn code, one thing is critical, learn by LISTENING, not by looking at a
chart. When you learn looking at a chart, in your mind you have to hear the
sound, then convert it to an image, then to the letter. Learning by sound
allows you to hear di-di-di and immediately think S. This becomes critical as
your start copying long words and gain faster speed. Buy some of the code
practice tapes or CD’s, and spend a little time studing. I learned listening
while driving.
In addition to just getting your HF privileges, there are other reasons this
is advantageous. For example, CW (contentious wave), the method the code is
used with, is much, much more efficient than any voice mode. When voice fails
to get through, CW will if it can be done at all. CW lets you do more with
less , power wise. Many hams have literally worked every state with small
homebuilt rigs in Altoid tins powered by 9v batteries, power output of 300mw.
Also, it can be used in many other situations. You can literally communicate
with mores with flips of the finger, winks, or taps on a table. I have several
times discreetly tapped out a message on a table to a buddy with nobody else
there any wiser. I once was in Poland and met a ham, but he did not know any
english. Using the standard abbreviation and signals, we exchanged calls,
hometowns, etc.. One ham I know was in a bad accident and when he woke up was
on a ventilator. He was unable to speak do to that, and was in much more pain
than the doctors though. Once a fellow ham visited, he was able to squeeze his
hand and tell him what he needed the doctors to know. So it has many more uses
outside radio.
Also, even if most people do hear your transmission, most will still have no
idea what your saying.
Guys,
what I am posting is basicly the cliffs notes for the test. The information is
taken directly from what you need to know to pass the test, without much of
anything else!
Here are
the Lessons-
Lesson

T1
Commissions Rules - T1A Amateur Radio, F.C.C., License Classes, Renewal
F.C.C.
The
Federal Communications Commission in Washington makes and enforces all the
rules and regulations pertaining to amateur radio. They can grant or take away
licenses or impose fines on amateurs if they are not following their rules.
An
amateur station in definition is a station in the amateur service who is
responsible for radio communications. Any licensed amateur who is responsible
for the stations transmissions is called the control operator. For Example: If
you allow your friend to use your radio equipment to talk, then you are
responsible for his transmission because the station is yours.
Purpose
of Amateur Radio
What
is the purpose of amateur radio. Well, there are several purposes but I won't
bore you with them. For now all you need to know for the test is the
following: To increase the number of trained radio operators and electronics
experts, and improve international goodwill.
Amateur
Radio License
In
order to operate a station in the U.S., an F.C.C Amateur Primary License is
required. This license is good for a period of ten years after which it must
be renewed.
How
Soon Can I Operate My Station?
As
soon as the FCC's computer database shows that you have been granted a
license, you are authorized to operate your station if you wish.
License
Classes
The
F.C.C. has broken the Amateur Radio Service into 3.5 license classes. You must
start as a Technician class operator and climb the ladder.(You can't skip. You
must start out as a Technician and work your way up to the highest license
class.) If you wish to gain more privileges than the ones you have, the F.C.C.
requires that you pass an exam for you to gain the additional privileges of a
higher class license.
License
Class Privileges Requirements
1)
Technician Class Full privileges in the VHF and UHF amateur spectrum above 30
MHz. Requires that you pass a 35 question exam.
1.5)
Technician with Morse Code Limited Morse Code and Voice Privileges in the HF
spectrum. Requires that you passed the previous exam with the addition of a
5wpm (words per minute) Morse Code Exam.
2)
General Class Limited Access to all the HF amateur bands with Morse Code, data
and voice modes. Requires that you have already passed the Technician and
Morse Code requirements with the addition of the General Class 35 Question
exam.
3)
Amateur Extra Full amateur radio privileges. Requires that you have passed the
General Class exams with the addition of the Extra Class 50 question exam.
License
Renewal
Once
you get your license it is good for ten years. After the ten years are up you
must renew it again for another ten years. You have up two years to renew.
During this 2 year period your license has expired and your amateur radio
privileges will not exist. Once you renew your license you may operate your
station as usual. The F.C.C recommends that you renew your license 90 days
before your license expires. This way your privileges will not disappear after
the expiration date.
Summary
1.)
The F.C.C.(Federal Communications Commission) enforces all amateur radio rules
and regulations.
2.)
An amateur station is a station in the amateur service who is responsible for
radio communications
3.)
Any licensed amateur who is responsible for the stations transmissions is
called the control operator
4.)
There are 3.5 license class: Technician, Tech with Morse Code Endorsement,
General, and Amateur Extra.
5.)
Your amateur radio license is good for ten years after which you have 2 years
to renew it.
6.)
You may operate your station as soon as the FCC's database shows that you have
been granted an amateur primary license.

T1
Commissions Rules - T1B Technician Frequency Privileges
VHF/UHF
Bands
The
F.C.C. authorizes a Technician with No Morse Code Licensee to operate on
authorized frequency segments (or bands) above 30 MHz. This region is called
VHF and UHF for Very High Frequency and Ultra High Frequency. Much of the
activity here is local to your area. These bands are fun and you will meet
many people here.
The
Bands
The
VHF and UHF bands are labeled by wavelength not frequency. If you are talking
about a segment of frequencies it would not be wise to say: "I bought a
radio that works on the 50.0 to 54.0 MHz Band." It is much easier to tell
your friend that your radio works on the 6M VHF band. The number "6"
for Six Meters stands for the wavelength of the radio wave in the 50 MHz
region.

The
High Frequency Privileges
If
you are a Tech who has not passed his 5-wpm Morse Code Exam, you will not have
any HF Privileges, but you will still be required to know and understand the
HF bands and the specific rules. Do not skip learning the HF frequency limits
even if you never will be upgrading your license to a Tech. + Morse Code. You
will be asked to know the frequencies of the HF bands on your Technician Class
exam.
Summary
1.)
Study and memorize the frequency limits of the VHF/UHF and HF bands above.
This
is important since the test will contain questions where the frequencies may
look similar but are incorrect.
Lesson

T1
Commissions Rules - T1C Emissions Privileges
Emission
Privelages HF
As
a Technician Class operator with morse Code Upgrade, you have HF privileges in
the following bands: CW only on 80,40, and 15 meters, and CW and data only on
10 meters from 28.1MHz to 28.3 MHZ. Also with SSB phone and CW only from 28.3
to 28.5 MHz.
You
do not have FM phone privelages on any of the HF bands. But you do have FM
phone prielages on the VHF bands from 6 meters (50.1MHz and up.)
VHF
Emission Privelages
Both
6 and 2 meters have a "CW only" portion for the band.
6m
50.0 - 50.1 MHz CW only
6m
50.1 - 54.0 MHz Phone emissions allowed(FM included)
2m
144.0 - 144.1 MHz CW only
2m
144.1 - 148.0 MHz Phone Emissions allowed, FM included.
Image
Transmissions
Image
transmissions are allowed on 2m, 1.25m, 70cm, and all other UHF bands above
70cm included. But beware! Image transmissions are not allowed within the
"CW only" part of the 2m band.
What
are image transmissions? Image transmissions are transmissions of either
moving pictures(video) or still images. Exaples of image transmission modes
are: FAX, Slow and Fast Scan Television. In other words television or FAX
methods. Many hams participate in slow scan or fast scan TV, and transmit
video of themselves to other hams.
Summary
1.)
Tech. Class with Morse Code have priveleges in the HF bands, but no phone
priveleges. They still keep their FM phone priveleges above 50.1MHz.
2.)
Both 6m and 2m have a "CW only" portion of the band.
3.)
Details about Emission privileges.
4.)
Image transmissions allowed on 2m, 125 and 77cm and above.
5.)
No image transmissions allowed in "CW only" portion of 2m band.
6.)
Image emissions are instances where still or moving pictures are transmitted.

T1
Commissions Rules - T1D Licensee Responsiblity
Control
Operator
A
station control operator is any licensed amateur who is responsible for a
stations transmissions. If you are licensed and own a radio, then you are the
control operator when you use the radio. The FCC requires that the control
operator be at the control point when the station is transmitting. The control
point of a station is the location where the control operator function is
performed. The station licensee and the control operator can be two separate
people. Any licensed amateur whom the station licensee chooses can be a
control operator. Both the station licensee and the control operator are
responsible for the station operation, but ultimately the station licensee is
responsible for proper operation of the station in accordance with the FCC
rules.
Terms
You Should Know:
Station
Licensee: The person who is licensed by the FCC to operate an amateur radio
station according to FCC rules.
Control
Operator: The person who is operating(using) the radio equipment.
Control
Point: The control point is the point where the control operator operates his
station.
Identification:
The FCC requires all radio amateurs to identify their transmissions with their
station callsign's.
Callsign:
A short number and letter sequence issued to you by the FCC to be used for
identifying your station. Examples: KG6XOR, WA1N, AC9QA, N7NA.
Identification
When
you have earned your license the FCC will issue you a callsign. What kind of
callsign you get depends on which country you live in and which state you live
in. This callsign is your ticket to the air. Without one you cannot operate
legally. The FCC requires that you identify your station every ten minutes
and/or at the end of your contact with your callsign. Each station must
transmit its own callsign at the end of a contact. You may always use CW to
identify your station.
An
Oddball Question You May See On the Exam:
If
you are a Technician with a Certificate of Successful Completion of
Examination for Morse Code you do not need any special form of identification.
Summary
1.)
Control operator is the person at the control point.
2.)
Control Point is the point where station is operated.
3.)
Station licensee is responsible for station operation according to FCC rules.
4.)
Station licensee can chose any licensed amateur to be the control operator.
5.)
Station identification is required at the end of all transmissions.
6.)
Both stations must identify after a contact even if the transmission is a
little longer or shorter than 10 minutes.
Lesson

T1
Commissions Rules - T1E Third Party
Third
Party
Third
party communications is where a message is sent between two amateur stations
for someone else. A "third party" is a person who is sent a message
by way of two amateur stations relaying the message to them. The FCC's policy
is that amateurs may never be paid for their communications third party or
not."For example: Aunt Mary pays you to send a message to Uncle Bob, who
is a ham radio operator." This behavior would be illegal.
If
you let a third party(like a friend) use your amateur station then you must
closely monitor and supervise your third party's transmission.
Third
Party International
Third
party messages to a foreign country may only be transmitted if the US has a
third party agreement with that foreign government, or the third party is
qualified to be a control operator.
When
a US station is sending third party communications internationally then the US
station must transmit BOTH callsigns at the end of a contact.
Terms
You Should Know:
Third
party communications: Communications between two amateurs intended as a
message for another person who is a not a radio amateur.
Third
Party: The person who receives the communications through amateur radio, but
is not a radio amateur. Can also be a friend who uses your radio equipment to
talk to someone, while "you" the station licensee, supervise.
Summary
1.)
Third party communications is where a message is sent between two amateur
stations for someone else.
2.)
A "third party" is a person who is sent a message by way of two
amateur stations relaying the message to them.
3.)
You may never be paid for your radio communications transmissions.
4.)
A third party agreement must exist between the US and foreign country's
government in order for third party transmission to be legal.
5.)
Each station must state both station's callsign's at the end of a third party
contact to another country.

T1
Commissions Rules - T1F Spectrum Use, Repeaters, Power Limits, Data Transfer
Sharing
Frequency Spectrum
On
many frequencies above the 70cm band, amateur radio operators are not the only
users of the band. Here the FCC allows more than one radio service to use the
band. In these instances amateur radio operators share the band with the other
radios services as secondary users.
When
amateurs are secondary users of a band, you must never interfere with the
primary users of the band. If you hear another radio service using a
frequency, you must leave and use another frequency which is not in use. This
rule also apply's to fellow amateurs. You must not interfere (or transmit)
when another amateur is using the frequency.
Repeater
Coordination
If
you wish to setup a repeater you must first obtain a recommendation from your
local frequency coordinator. (The FCC doesn't recquire that you get a
recommendation, but if there is a dispute, the FCC will side with the repeater
that has received recommendation.) The Frequency Coordinator's job is to make
sure your repeater will not interfere with nearby repeaters already
established.
Repeater
Interference
If
two repeaters are causing interference to one another, and one has been
recommended by a frequency coordinator, and the other not, then it is up to
the licensee of the un-recommended repeater to resolve the interference.
In
the case in which two repeaters are interfering and neither repeater has been
recommended by a frequency coordinator, then both licensee's of the repeaters
are responsible for resolving the interference.
LEGAL
POWER LIMITS
The
FCC limits the power levels ham radio operators can use in terms of Peak
Envelope Power, or PEP for short. This is a fancy term for "The average
power applied to an antenna transmission line during one RF cycle at the crest
of the modulation envelope." You need to understand this term because it
will be used often to describe your radio and how much power your radio
transmits one the airwaves.
Power
Limits
Maximum
Power Output Technician for All VHF and UHF bands is 1,500 Watts PEP.
Maximum
Power Output allowed to Tech. with Morse Code Endorsement Operators on the HF
bands is 200 watts PEP.
NOTE:
You must always use the minimum amount of power necessary to communicate. If
you only need a low amount of power to reach your buddy across town, then down
turn on your amplifier. It would be illegal since the extra power from the
amplifier is unnecessary.
Digital
Communications
Terms
to Know!
Data-
Telemetry, Telecommand, and computer emissions
RTTY-
Narrow-band direct-printing telegraphy emissions
Maximum
Symbol Rate- A term used to indicate the speed of the transfer of digital
information. Most often indicated in kilobauds or kilobytes.(As in
56-kilobytes per second(56kpbs).
Maximum
Symbol Rate for the VHF Bands The maximum symbol rate allowed for digital
communications on the 2 meter AND 6 meter bands is 19.6 kilobauds.
Summary
1.)
FCC Rule: Primary users of frequencies must not be interfered with by amateur
radio operators.
2.)
FCC Rule: You must never interfere with amateur radio communications. Everyone
has an equal legal right to a frequency.
3.)
Repeater frequencies and setup is organized through a frequency coordinator.
4.)
Make sure to know the two repeater interference cases outlined above, well.
5.)
PEP - Peak Envelope Power: The average power applied to an antenna
transmission line during one RF cycle at the crest of the modulation envelope.
6.)
Technician Class Power limits: VHF-UHF: 1,500 watts PEP.
HF:
200 watts PEP.
7.)
FCC Rule: Always use the least amount of power needed for a radio contact.
[Don't run more power than you really need!]
8.)
Make sure you know the above vocabulary terms and understand their meaning.
Lesson 7
T1
Commissions Rules - T1G Space Communications, False Signals, Interference
Space
Stations
Amateur
Radio Satellite
An
amateur space station is a station located 50 kilometers or more above the
earth's surface. Any licensed amateur can be the licensee of an amateur space
station, even a Technician. Getting your station or satellite into space is
much more of a problem! Also, remember that 6 meters may not be used by earth
stations for satellite communications.
False
Signals
False
or deceptive amateur signals may never be transmitted. You may never fake an
emergency by transmitting a "MAYDAY" call on the air. This is
classified as a deceptive signal because you are transmitting a call for help
in an instance where there is no emergency.
Unidentified
signals are illegal, except for transmissions from a space station or to
control a model craft. You must always identify with your station callsign
each time you transmit.
For
Example: Many times ham radio operators will transmit for a brief period of
time to check if they can make it into a local repeater, without giving their
station identification. This is illegal and classified by the FCC as an
"Unidentified Transmission".
Interference
You
must always be careful to NEVER deliberately interfere with another stations
communications.
For
Example: If another amateur repeatedly transmits on a frequency already in use
by another group of amateurs, the interference case is illegal and classified
as "Harmful or Malicious Activity". Any transmission which disturbs
other communications is called "Harmful Interference".
Summary
1.)
An amateur space station is an amateur station located at least 50 kilometers
above the earths surface.
2.)
Any licensed amateur can be the licensee of an amateur space station.
3.)
6 meters may not be used by earth stations for satellite communications.
4.)
You must never use the word "MAYDAY" on the air to FAKE an emergency
.
5.)
You must identify your transmissions every ten minutes or at the end of your
transmission if it was less than 10 minutes long.
6.)
Understand the terms: "False Signals", "Unidentified
Signals", and "Harmful and Malicious Interference".
Lesson 8
T1
Commissions Rules - T1H - Correct Language, Beacons, Radio Control Craft
Correct
Language
If
you're bilingual, and you speak another language other than English, then
you're in luck! The FCC allows communications on amateur bands in languages
other than English So long as you send your station identification(callsign)
in English. In fact there are many German, Japanese, and Latino groups who
meet to speak their language on the air.
Beacons
On
various bands, there are special transmitters which operate 24 hrs as and
indicator to amateurs about radio conditions and propagation. All you have to
do is tune to the beacon frequency and listen for the beacon's signal. If the
signal is present, then you know that a radio communication path exists
between your country and the country or continent in which the beacon is
located in. As a limit, beacons are limited to only 100 watts PEP. Any
licensed amateur with at least a Technicians license can setup and become the
licensee of a beacon or repeater.
Radio
Control
To
use a radio control transmitter on an amateur band, you must affix(attach)
your station callsign, name, and address onto the transmitter. You may use up
to 1 watt PEP of power for the tele-command(control) of your craft or vehicle.
More than 1 watt would not be reasonable, because more than 1 watt would be
enough to cause erratic operation of nearby radio controlled craft. Plus, 1
watt is enough power to control your craft or vehicle within mile of your
location!
Summary
1.)
You may communicate on amateur radio frequencies using any language as long as
you identify yourself with your callsign in English
2.)
Beacons are transmitters setup as indicators of worldwide radio propagation
conditions.
3.)
Any license class(Technician or higher) may be the licensee of a repeater or
beacon.
4.)
Beacons are limited in power to 100 watts PEP.
5.)
Radio control transmitters are limited to 1 watt.
6.)
To operate a radio control transmitter, it is required that you attach your
station callsign, name and address to the transmitter.

T1
Commissions Rules - T1I Emergency Communication, Indecent & Obscene
Language
Emergency
Communications
If
you hear a distress call on the radio, you should always contact the person
and get the proper authorities EVEN IF the signal is on a frequency outside
your license privileges.
MAYDAY
and SOS
The
words "MAYDAY" and SOS are only to be used as a distress call and
transmitted only in a case of life or property threatening emergency. False
alarms where life or property are not threatened are illegal.
Disasters
When
disaster strikes an area and severely disrupts normal communications systems
[such as police, fire, and gov'mt radio, telephone and cellphone systems], the
FCC may step in and declare a "Temporary State of Communications
Emergency". This results in the restriction of the types of transmissions
that radio amateurs may make. Only transmissions that are necessary to meet
essential communications needs to facilitate relief actions. Any special rules
to be observed during the emergency are posted in the FCC Declaration of a
Temporary Communications Emergency.
Broadcasting
Broadcasting
is never allowed for any amateur of any license class Technician or not. It is
illegal according to FCC Rules to transmit material intended for the general
public.
WHY?
- Because amateur radio service was not intended for broadcasting.
Words
to Know
Broadcasting:
Transmissions intended for reception by the general public, either direct or
relayed.
Indecent
and Obscene Language
You
may never transmit obscene or indecent language from your amateur station
because:
1.)It
is offensive to some individuals.
2.)Because
young children may intercept amateur communications with readily available
receiving equipment.
3.)Because
such language is specifically prohibited by FCC rules.
The
FCC does not publish a list of prohibited words. The FCC says: "If you
beleive a word is questionable, don't use it in your communications." In
other words, use common sense. Most everyone knows what type of words are
indecent in todays society.
Summary
1.)
In an emergency situation it is legal to transmit outside your license
privileges for emergency purposes,
2.)
MAYDAY and SOS may only be used in an instance where life or property is
threatened.
3.)
During disasters the FCC may limit amateur communications to only
transmissions that "Are necessary to meet essential communications needs
to facilitate relief actions.
4.)
FCC may post special rules for amateurs to follow in a declaration of
communications emergency.
5.)
It is illegal to broadcast material for the general public.
6.)
It is illegal to transmit indecent and obscene language.

Operating Procedures - T2A Operating Rules and Procedures
Overview
This
part of the test contains questions regarding basic operating rules. These are
rules you should know to be able to go on the air and use a repeater or be
prepared to handle emergencies. Most of these rules are not set by the FCC,
but are common knowledge that every radio amateur should know in order to
operate his station properly.
Preparing
to Transmit
Before
transmitting ALWAYS listen to make sure others are not using the frequency. If
you don't follow this rule, you won't make many friends in amateur radio, and
you will make yourself look like a fool.
If
you are conducting a lengthy transmitter test, or loading up procedure, it is
best to use a dummy load. Dummy loads are standard equipment in a ham shack.
Read the following caption for more info.
Dummy
Load
A
dummy load is a large resistor capable of dissipating the radio energy from
your transmitter as heat into the air. This capability is necessary during the
testing and repair of radio gear. When repairing the transmitter of a radio is
often required to transmit for a short time in order to diagnose the problem.
But instead of transmitting an unnecesary test signal live on the air,
technicians connect a dummy load to the antenna jack. This allows them to
transmit a test radio signal that is absorbed in the dummy load.
Emergencies
If
you are in contact with another station and you hear a call for help on
frequency what should you do? In this case you should stop your QSO
(conversation with someone) and take the emergency call. Emergencies are
always priority traffic. Just like fire engines and ambulances have the right
of way in traffic on the road, emergency traffic on the radio has priority
over all other traffic on the airwaves.
Basic
Operating
To
minimize interference on HF bands capable of long-distance communication, it
is best to stick to VHF and UHF frequencies for local amateur communications.
Also,
during commuter rush hours, third party repeater nets are always discouraged.
During this time a lot of mobile hams will be using the repeater, and nets
(which are formal gatherings on the radio) are discouraged to allow mobile
hams access to the repeater.
Morse
Code
You
should always send your Morse code calls at a speed at which you can also
receive. It is not wise to send Morse code faster than you yourself can copy.
Many
hams on the air will be heard using the procedural sign "DE". This
is a word which means "From" or, "This is". For example:
KG7IKL de AD6XS ...means.... KG7IKL, this is AD6XS.
This
is a very commonly used sign in HF conversations, especially ones using
CW(Morse code). Although secret codes and ciphers are illegal, procedural
signs like "DE" are not classified as a code because they are
understood by most everyone and are used to make Morse code transmissions
simpler to send.
Summary
1.)
Before transmitting you should always listen first to make sure the frequency
is clear and open to use.
2.)
A dummy load is used when a an amateur desires to test or tune his radio
transmitting equipment without transmitting an audible signal on the air.
3.)
Emergency traffic always has priority orver all other radio traffic.
4.)
IF you hear an emergency call while speaking on the air with another amateur
you should always stop and assist the distressed party.
5.)
HF bands should not be used for local communications. VHF-UHF bands shoudl be
used instead.
6.)
The morse code procedural sign "DE" is a short-cut way of saying
"this is".

Operating Procedures - T2B Simplex; Communication modes; Q-Signals; Procedural
Signs
Operating
Rules
Simplex
Operations
What
does the term "simplex operation" mean? Simplex operation is where a
station is transmitting and receiving on the same frequency. Remember,
repeaters received and transmitted on different frequencies. Simplex operation
should be used instead of repeaters when communication with the intended
station is possible without using the repeater. This is recommended because it
will reduce traffic on repeaters and prevent it from being tied up
unnecessarily.
But
if you are on a repeater talking with another station, how can I tell if I can
communicate using simplex instead?
The
answer is simple. Most radios let you switch to the frequency that your friend
will be"transmitting" on. This is the frequency that is called the
"input frequency" because here your friends signal is being received
by the repeater.
If
you listen on the "input" and you can hear your friend's voice
clearly, then simplex "one on one communication is possible.
Next
you can switch back to the repeater and suggest that you switch to simplex
operation.

RST
Reports: An RST report is a report from another station on the quality and
strength of your stations radio signal. Here is what it means:
R
Readability - On a scale of 1 to 5, the readability of your signal. In other
words the ability of the other operator to understand what you are saying.
S
Strength - On a scale of 1 to 9, indicates how strong your stations signal is.
T
Tone - Used for morse code signal reports. Indicates on a scale of 1 to 9 the
quality of the tone of the morse code "beeps". From a "pure
tone" To an ugly "60 cycle harsh tone".
For
example: a report of "599" means the following: The five mean your
signal is easy to understand. The first nine means your signal registers a
about nine on their signal strength meter. The second nine (only included if
you are using morse code) means your CW tone has a nice pure tone.
In
some cases people may tell you: your signal is five nine plus twenty dB... In
this case the twenty db part indicates that your signal is so strong that it
goes off the standard 1 through 9 signal strength dial by twenty decibels.
This would mean that you are putting out a REALLY strong signal!
Calling
CQ
Used
very commonly on the HF bands, the sign "C-Q" means: calling any
station.
Say
"CQ" three times, followed by "this is," followed by your
call sign spoken three times.
Answering
a CQ call.
To
answer a CQ call, say the other stations callsign once, followed by "this
is", then your callsign given phonetically.
QSL
Cards
A
QSL card is a letter or postcard sent as proof that two amateur stations have
engaged in an actual radio-chat. For example: Bob uses his station in
Pennsylvania to talk to a ham in Brazil. As proof of his achievement Bob, and
the Brazilian operator exchange a card describing the details of their
contact(like the time, date, frequency, and power).
Full
Quieting
This
term is used to indicate that your signal is strong enough to over come ALL
receiver noise. This term is used primarily on FM simplex and repeater use to
indicate your signal strength. (RST reports are usually not used.)

Emergencies
Distress
Calls
Phone
- (SSB or FM) MAYDAY several times
CW
- (morse code) S-O-S, then send your callsign.
On
Repeaters Say "BREAK" twice, then your callsign.
Distress
calls are only to be used when there is a threat to life or property.
Otherwise, a fake distress call is expressly forbidden on any frequency
amateur or not.
Tactical
Callsigns
During
emergencies you may hear tactical callsigns like "Command Post" or
"Weather Center". These are used because they are more efficient and
help coordinate public-service communications.
Types
of Messages During Emergencies
Only
messages concerning "Health and Welfare" traffic related to the
emergency are sent.
Your
Emergency Station Components
Good
accessory to have for a small hand-held radio in an emergency is several sets
of charged batteries. A good choice for a portable HF emergency station is a
dipole antenna.
RACES
RACES
is an organization which is part of amateur radio emergency communications.
RACES works in conjunction with law enforcement and local governments in a
large scale disaster. They are trained emergency professionals who provide
emergency communications when a disaster occurs. They also do all their work
for no cost.
The
maximum hours allowed for RACES drills is one hour. During a RACES Drill you
must identify your messages as drills or test messages.

VOCABULARY
TERMS
The
terms below are to be memorized. There are questions referring to each one of
them concerning their meaning or definition. Don't miss out. Learn them!
PACKET
RADIO TERMS
Connected
Two packet stations are connected to each other. The receiving station reply's
that the information has been received correctly.
Monitoring
Means a receiving station is displaying all the messages on frequency and is
not replying to any message.
Digipeater
A packet-radio-station that only re-transmits data that is marked to be
re-transmitted.
Network
A way of connecting packet-radio stations so data can be sent over long
distances.
Operating
a Packet Station
Packet
operation is never to occur on simplex frequencies. Digital operation should
be avoided on simplex voice frequencies.
Radio
Tele-Type
Radio
tele-type is one of the earliest types of digital transmission used on the
radio. it was used to a very large extent as a message transmitting system. It
is still a very commonly used way of communicating on the ham radio bands. The
following will help you get familiar with questions on the exam about RTTY.
Answering
a CQ
When
using the RTTY mode, always use the same speed to reply to a CQ as the sending
station. Remember, CQ means a call for any station. This means any amateur
sending a CQ is saying in effect "I am on the air and I would like to
talk to any other radio amateur that can hear my signal."
Modes
of Operation for Technicians with No Code
Technicians
without morse code are not allowed to operate CW or SSB on the HF bands. Only
Technicians WITH morse code endorsement, General, and Extra Class operators
are allowed to operate in the HF frequency spectrum.
Aircraft
You
may have wondered if it is legal to operate your ham radio station aboard an
aircraft. Especially a commercial airline flight. Well, you may be
disappointed to hear this but, ham radio signal often interfere with the
flight radio systems. This means that most airlines will not allow you to use
your personal hand-talkie on the flight. The rule is you can operate on a
commercial aircraft only with the pilots specific permission and not while the
aircraft is operating under Flight Instrument Rules.
Operating
Outside Your Station Address
You
can operate your amateur radio station anywhere in the U.S. other than your
the address written on your license. This means you can operate anywhere, not
just from home.

Repeaters
What
Are Repeaters?
In
most cases propagation on the VHF-UHF bands are line of sight. This means that
VHF and UHF signals tend to travel in a straight line, and cannot travel as
far as HF signals can. Amateur radio operaters in the early days found that
VHF signals were easily blocked by mountains and hills, even trees could cause
a significant reduction in signal levels. To help amateurs communicate on the
VHF and UHF bands, ham radio operators invented a special machine called a
"repeater".
A
repeater consists of special radio equipment and antennae on top of a high
point where it can relay weak VHF signals from far away and improve VHF-UHF
communications.
How
Does a Repeater Work?
A
repeater works the following way:
1.)
A repeater setup on a high hill or building RECEIVES a weak signal from
Kevin's small low powered FM handi-talkie ( a small hand held VHF transceiver)
on its INPUT frequency.
2.)
The repeater takes the weak signal, amplifies it and re-TRANSMITS it on a new
frequency called the OUTPUT frequency, several kilohertz or megahertz above OR
below the transmit frequency.
3.)
Several amateurs at a nearby hobby convention receive Kevin's signal on the
repeater's output and decide to respond to his call.
End
Result: Kevin's weak low-power radio with only a range of a mile or two, now
is able to use a mountain-top repeater which can extend the range of his radio
to cover more than a hundred square miles of distance. WOW! That's what ham
radio is all about!
There
are several important things to note about repeaters.
OFFSET
- The difference between the input and the output of a repeater is called the
offset.
Example:
On the Two Meter Band the standard repeater offset is 600kHz. A repeater
output on the 2m frequency of 146.000MHz will have a standard offset of
+600kHz this means that you should set your receiver to transmit on the input
at 146.600MHz . Vise-versa, an offset of -600kHz would mean you would have to
transmit at 145.200MHz.
INPUT
- The frequency your transceiver is programmed to transmit on whenever you
press the transmit button on your radio. (this is the frequency the repeater
listens on.)
OUTPUT
- This is the frequency your radio is programmed to, to recieve the repeater's
signal after you release the transmit button and finish speaking. (this is the
frequency the repeater simultaneously re-transmits your signal on.)
AUTOPATCH
- Some repeaters also have a special ability called an autopatch. An autopatch
is a device which allows radio users to access the public telephone system. If
you have permission from the owner of a repeater, any ham radio operator can
make a telephone call through the autopatch using special radios equipped with
telephone touch tone keypads. (Most VHF transceivers come standard with this
numerical key-pads)
PL-Tones
- Many repeaters across the country have PL-Tones® also called a "CTCSS"
Continuous Tone Coded Squelch System. A PL-Tone is a sub-audible (humans can't
hear it) tone which rides along your radio signal and tells a repeater to
allow or deny you access. If you have the wrong Pl-Tone programmed into your
radio, or if you have no Pl-tone at all, these repeaters will reject your
signal. In effect your voice will not be heard by anyone using the repeater.
Open
Repeaters
- Open repeaters are those which are free for use by any licensed ham. Most
repeaters are this type, and are maintained and paid for by local area ham
clubs. Some repeaters are closed systems. This means you must be a member of
the organization which maintains the repeaters. Often these repeaters have
something to offer like better coverage, or an autopatch for telephone calls,
or a linked repeater system.
Time-Out
Timers
- Time-out timers are timers which are set on a repeater to cut short
transmissions longer than the timer's limit. The timer is set off when a
operator transmits a transmission longer than the timer limit. When this
happens the repeater goes silent for a minute or so after which it is reset,
and the repeater can be used once again. The timers are used to make sure hams
shorten their transmissions to allow others to break in and use the repeater.
Courtesy
Tones -
A courtesy tone is a sound used to indicate when a transmission is complete.
Repeaters make a special beep when you let go of a microphone key to let you
know your transmission has been completed.
Summary
1.)
What a repeater is.
2.)
Understand what an "offset", "Pl-tone", "courtesy
tone", and "autopatch" are.
3.)
Understand in detail how a repeater works.
4.)

Repeater
Operation
Etiquette
Repeaters
are places where there are certain accepted rules for communications. For
example, don't make an autopatch** call while two ham friends are talking,
using the repeater.
Here
are some accepted rules you must learn for the exam:
Pause
briefly between transmissions, to listen for anyone wanting to break in.
Keep
your transmissions short, because a long transmission may prevent someone with
an emergency from using the repeater.
The
proper way to break into a conversation on a repeater is to say your call sign
in between transmissions.
Make
sure that you listen to the repeater before making a transmission, to prevent
interrupting a conversation already taking place on the repeater.
To
call another station you call another station say the stations callsign then
identify with your station with your own callsign.

Because
repeaters "listen" on one specified frequency and
"broadcast" the information they hear on another separate frequency,
a standard was set for each VHF/UHF band for the amount of frequency shift
between the"input" and the"output" of the repeater.
You
must memorize this repeater information, because it may possibly be on the
test.

Radio-Wave propogation - T3A Line of Sight; Reflection of VHF/UHF Signals;
Ionosphere
VHF
Signal propogation
Line
of Sight
VHF
and UHF radio signals tend to travel in straight lines going all directions
out from the source. VHF and UHF signals can travel large distances as long as
major obstructions are not present. But once an obstruction (like buildings or
trees) gets in the way, the signals are stopped, or weakened. A problem occurs
when we wish to use a VHF/UHF signal to contact someone beyond our horizon.
Since VHF/UHF signals tend to travel in straight lines, and the surface of the
Earth is curved, the signal will not bend around the curvature of the earth,
instead it will continue in a straight line forever going out into space.
Thus, the distance VHF signals can travel is severely limited, by the
curvature of the Earth's surface.
VHF
propogation can be described in most instances as line of sight propogation.
This is because they travel as far as the human eye can see to the horizon.
Because of the earth's surfaces curvature, signals leave the earth's surface
beyond the horizon. In summary, VHF/UHF signals can be described as having a
point to point propogation which travels outward in a straight line from the
radio transmitter to the receiver in a straight line called "line of
sight propogation".
Radio
Signals and Metal Buildings
Although
VHF/UHF signals travel in straight lines out from their source, they also tend
to reflect off of metal objects. The larger the metal surface the greater the
amount of reflected signal. Usually large metal objects such as aircraft and
buildings reflect VHF/UHF signals the best. Sometimes this special
characteristic of VHF/UHF signals is used as an advantage in large cities
where many buildings can block other signals.
Ionosphere
Getting
Familiar with the Ionosphere
The
ionosphere [EYE-ON-OH-SFIHR] is a layer of atmosphere miles above the Earth's
surface on the edge between space and life. It is a region of the Earth's
upper atmosphere upon which all of High Frequency and Medium Frequency
long-distance radio propogation depends. In this region high above the earth,
the ionosphere reacts to the ionizing radiation of the sun's Ultraviolet rays.
These ultraviolet rays strike the ionosphere and leave "charged
particles" behind called ions. When the ionosphere is charged by the
sun's radiation, these particles refract or "bend" radio signals
back down towards Earth. These ion particles form charged layers within the
ionosphere, which are responsible for the amazing signals you can hear from
distant lands on the amateur radio bands.
The
Layers Within the Ionosphere
The
ionopshere's charged particles form four distinct regions or layers within the
earth's atmosphere. These layers can be further grouped into two additional
categories. Ones which exist only while the Earth's surface is in view of the
sun, and ones which exist only while the earth's surface is hidden from the
sun (in darkness).
Daylight
Regions Night-time Regions
F1
F Layer [F1+ F2 Combined]
F2
E
D
The
two F layers, the F1 and F2 combine during darkness into one layer. The E and
D layers rapidly disappear as the earth enters into darkness.
The
F Layers
The
"F" Layer is the layer most responsible for world wide amateur radio
communications. Radio signals strike this layer and are bent back at a angle
towards earth with little signal loss. During the daytime, the F layer splits
into 2 layers called the F1 and F2. The F2 layer is the outermost layer, and
is the one which refracts signals the most during daylight hours.
E
Layer
Th
E layer exists in between the F and D layers, and forms only during daylight.
Some radio refraction occurs in the E-layer at very high frequencies (VHF).
This phenomenon is called Sporadic-E, because of it is very sporadic in
nature.
D
Layer
The
D layer is the closest layer to the earth's surface, and also forms only
during daylight hours. This lay
