Code of Federal Regulations
Federal Communications Commission (FCC)
Emergency communications are quite important
Which box is on top
International goodwill
A written authorization is a license
Personal radio sevice
A control operator is a licensed amateur who is responsible for the proper operation of the station.
License testing
Transmit on ham bands
Amateur Radio service
All US areas, on board US ships, etc.
Any number - you are responsible for their proper operation
An EC license WITHOUT a reciprocal permit
Notice That Generals Are Amply Elevated
Novice & Tech
Tech
F(in MHz) = 300/WL(in meters). Pick the smallest limit in the correct band.
Pick the smallest limit at bottom of the band
Pick the oddest answer
WL = 300/F(in MHz) = 300/3.7 = 81 meters. Pick the closest answer.
No 007's
Any
All code tests are Element 1( )
Where to mail your license
Get a replacement
Send a Form 610 to PA
All US calls start with A, K, N, W and have a single number 0 - 9

On 10 Meters
Save money and use the minimum power
Novice limit of 200 watts
Novice limit is 200 watts

Proper operation
The control operator must be licensed
Must keep station records
Higher license
Your license
When transmitting
Control point
Any time
Authorized
The rules on business communications have been changed.
All of these can now be discussed. Business planning might better be discussed over a cup of Java.
Yes, you can now use Amateur Radio. A phone call might be a better way.
Ten minutes
Call sign
None
Own call
Both call signs at end of each communication
Third-party communications are messages sent for someone other than the control operators.
If not prohibited
Above 50 kilometers
Was Extra only - now any licensed amateur
If special requirements are met
Never
The person getting or sending a message (if not a control operator)
Check for a third-party agreement
Third-party agreement or to a control operator
Interference
Might block an emergency message
Deceptive - "MAYDAY" is for emergencies
Unidentified
In any way possible
In an emergency
Listen and ask
Dummy load - Dummy antenna
Take the emergency call
3 by 3
2 by 2
Don't send faster than you can receive

Over
Distant
Regards
RST is Readability, signal Strength and Tone
Slowly
Location
Written proof
1 by 1
Phonetics
Same
Replying
Not replying
Marked to be retransmitted
Long distances
Transmitting and receiving on the same frequency
If possible
Input or "offset"
Increase the range of portable and mobile stations
Receive and transmit frequencies
Allows telephone calls
Limits transmit time (to 3 minutes)
Sub-audible
Line-of-sight is the term for a signal that travels in a straight line
Reflected
The surface of the Earth is called the ground
Longer
Sky wave
Signals are bent (refracted) back to earth
Skipped means missed
Ionosphere
The more - the greater
Eleven years
Key-operated - like some computers
Remove some or all of it
Limit access
Protect from lightning damage
Ground everything
Disconnect everything
NEVER use a natural gas pipe. Use a metallic cold water pipe (or a ground rod).
Copper
Eight feet
Keep antenna away
Do you run your microwave with the door open?
Low loss
To avoid being cooked
UHF range (1270 MHz)
Safety
Mountain climbers use them
The ground is hard
Higher than electrical lines is good - NEVER go over high-voltage lines
Protect your head
The Standing Wave Ratio is an indication of impedance match
Close to the antenna
Best
Fair
Mismatch
Jumpy
Mismatch due to open, short etc.
Too long
Too short
May not be accurate
Too strong signal(s)
Frequency independent
Receiver overload
Harmonics are multiples of your transmitter frequency. The third harmonic of 15 meters is TV channel 2.
High-pass on TV
Low-pass on transmitter
Harmonics are multiples - 2 times, 3 times etc.
May cause interference
Prevents unwanted radiation
Check your own television
Mega is a million and kilo is a thousand
A meter is 100 centimeters
A milliampere is .001 amperes
A millivolt is .001 volts
Micro is 1/1,000,000
Pico is micro-micro
Kilo is a thousand
Milli is 1/1000
Current is the flow of electrons and it is measured in amperes
EMF - voltage
Volt
About 13.6 VDC when fully charged
About 117 VAC
Gold, silver & aluminum
Plastic & porcelain
It does not let electricity flow
Resistance
Ohm
Ohm's Law
Voltage = Current times Resistance E = I*R, E = 2*50 = 100 volts
If E = I*R then I = E/R, I = 200/100 = 2 amps.
If E = I*R then R = E/I = 90/3 = 30 Ω
Power
The 100 watt bulb
Watt
Open circuit
Short circuit
Direct current (DC)
Alternating current (AC)
Frequency is the number of times (cycles) per second
Frequency is measured in Hertz. One Hertz is 1 cycle per second.
To 20 kHz
They can be heard by humans
20 kHz
Radio
Wavelength
Wavelength(in meters) = 300/F(in MHz)
F(in MHz) = 300/Wavelength(in meters)
It has one input and two outputs
It is a double "off and on" switch

Talk farther away and have it fixed
468/f (in MHz)
234/f (in MHz)
468/f (in MHz), 468/3.725 = 125.6 ft
468/f (in MHz), 468/28.15 = 16.6 ft
234/f (in MHz), 234/7.125 = 32.8 ft
234/f (in MHz), 234/21.125 = 11.1 ft
468/f (in MHz), 468/223 = 2.1 ft., 2.1*12 = 25.2 in.

The driven element is connected to the feed-line
Short elements are directors
The longest element is the reflector
Always toward the directors looking from driven element

While D is true - Safety, answer B is most important
Two conductors with a CO-AXIS (a center wire and outer sleeve)
Impedance matches amateur equipment - but it is hard to make at home
Coax
Parallel means side-by-side
High SWR and low loss
Needs matching and is not good near, or tied to metal objects

At antenna
An FCC amateur operator/primary station license
WL = 300/F(in MHz) = 300/7.125 = 42 meters.
WL = 300/F(in MHz) = 300/3.7 = 14.2 meters.
WL = 300/F(in MHz) = 300/3.7 = 10.7 meters.
WL = 300/F(in MHz) = 300/ = 1.3 meters.
To a transceiver
Connect a computer to a modem and connect the modem to the transceiver
Harmonics are multiples of your transmitter frequency. The third harmonic of 7125 kHz is 21,375 kHz.
Paper license need not be kept at station or on person.
There are now six amateur operator license classes.
License document need not be with you when operating.
