The American National Standards Institute (ANSI) has studied the effects of RF energy on the human body. They publish the `ANSI RF protection guide` which says `30 MHz to 300 MHz` causes the greatest risk from RF energy exposure. The `human body absorbs RF energy` the best in this range.~ B.Properly fill out FCC Form 610 and send it to the nearest FCC field office~ A.`Forward and reflected power`~ B.Donation of equipment repairs~ C.Use a non-resonant antenna~ How should you give a `signal report` over a `repeater`?~ If a `48000-ohm` resistor is connected to `12 volts`, how much current will flow through it?~ C.Right-hand circular~ An inductor (a coil) stores energy in a magnetic field which goes through the center of the inductor. If an `iron core` is `inserted into a coil`, the iron will concentrate the magnetic field. This `increases` the coil's `inductance` (its ability to store energy).~ If warm, dry air in the lower atmosphere (the troposphere) moves over cold, moist air, sometimes a "waveguide" for `VHF` signals is created which propagates the signals hundreds or thousands of miles farther than normal.

So, if a `4800-ohm` resistor is connected to `12 volts`, the current flow will be 12 / 4800 or 0.0025 amperes (`2.5 mA`).~ Most resistors are marked with a color code which shows the `resistor's tolerance value` along with its resistance value.

It `joins RG-213 coaxial cable`, RG-8, RG-11 and other popular sizes of coaxial cable.~ In what frequency range does `tropospheric ducting` most often occur?~ Most transmitters must be tuned up (adjusted) before they send out a good signal. `Interference` can be `minimized` if you use a `dummy load` instead of an antenna for tune-up.

Be careful when working near electricity. Your heart is the most important part of your body to protect from electric shock.~ As a general rule, the `feed line` between a transmitter and an antenna should be as short as possible. This is because the amount of signal a `feed line` absorbs `increases as length increases`. For least `signal loss`, keep the `feed line` short.~ A.As little as `1/500 of an ampere`~ What emissions are produced by a transmitter using a `reactance modulator`?~ B.A three-element Yagi~ language, identifying your station, English~ A.The temperature of the ionosphere~ A `Yagi` has at least `two` `straight`, `parallel elements`, a driven element and a reflector, `in line` with each other. Usually a few `straight`, `parallel` director elements are also added `in line` too. Radio energy is sent by the driven element in two directions, but energy going to the reflector is reflected back the other way.

This means that your RTTY or packet signals can shift frequency by any amount up to the maximum bandwidth allowed for the band when changing back and forth from "mark" and "space" (binary "1" and binary "0").~ When is the `E region most ionized`?~ `Image` emissions (facsimile and television) may be sent on any frequency in the `2-meter band` except for the CW-only range of 144.0 to 144.1 MHz. This means `image` may be used on almost all of the band, from `144.1 - 148.0 MHz`.~ What causes `VHF radio waves` to be `propagated several hundred miles` over oceans?~ What is a `parasitic beam antenna`?~ Which ionospheric region limits `daytime` radio communications on the `80- meter band` to `short distances`?~ D.Wait for the station to call "CQ," then answer it~ A couple of sets of `charged batteries` will let you operate a hand held radio for several hours `in an emergency`. Sometimes this can make the difference between life and death for you or someone else.~ B.On the back side of the cabinet, out of sight~ An `IF amplifier stage` picks out a narrow band of received frequencies and sends them to a `detector` circuit where they are combined with the steady signal of a `beat-frequency oscillator`. After the `detector` `combines` the two signals, it amplifies their difference, which is an audio signal.~ Certain types of coaxial cable absorb more RF energy per foot than others at VHF frequencies. If you wanted to connect a `6-meter Yagi antenna` which was `150 feet from your transmitter`, you'd want to use the type of coaxial cable with the least loss per foot so you'd get the most signal to your antenna. In this case, `RG-213` coaxial cable is the best choice.~ B.A reflectometer~ How can the `range of a voltmeter` be `increased`?~ D.`No payment` of any kind is allowed~ B.Shout, "break, break!" to show that you're eager to join the conversation~ C.Signal loss decreases as length increases~ A.To check the SWR of the repeater~ Voice signal reports are given with two numbers, readability and signal strength. Readability is a number from 1 to 5, (5 is the best). Signal strength is a number from 1 to 9, (9 is the best). So, if your signal report is `five nine plus 20 dB`, it means perfectly readable and `20 decibels greater than strength 9`.~ The `D region` of the ionosphere `absorbs` signals best during the `daytime`. Lower-frequency radio signals can't travel very far without disappearing because of this ionospheric absorption. Just remember that the `D region` in the `daytime` causes disappearing signals.~ What is the meaning of: "Your signal report is `five nine plus 20 dB`..."?~ D.Roll the excess cable into a coil which is as small as possible~ B.QRRR~ A.Wait for the end of a transmission and start calling the desired party~ C.Your signal is readable with considerable difficulty~ A repeater listens for signals on its input frequency and retransmits them more powerfully on its output frequency.

However, it needs a wide bandwidth, so it's not used below 29 MHz. Since `VHF/UHF repeaters` operate far above 29 MHz, `frequency modulated phone` is used for its good qualities.~ A.To the white wire~ A repeater uses a "`time out`" circuit to stop its transmissions from going on all day if there is a continuous signal on its input frequency, and to help keep normal transmissions short. If someone talks `longer than the repeater allows`, the repeater will "`time out`" and stop transmitting.~ overdeviation, FM, out-of-channel emissions~ A non-directional ground plane antenna is made when a `magnetic-base whip` antenna is placed on the roof of a car. The whip becomes the vertical radiating element and the car's metal roof becomes the grounded horizontal plane.

That way the `voltmeter` will measure the actual voltage that is passing through the circuit.~ The `National Electrical Code` is a book of standard `electrical safety requirements` for all kinds of electrical wiring, including amateur antennas.

The higher the frequency, the less bending. Since `sky-wave propagation` occurs when a signal is bent enough to return back to the earth, it will `least often occur` on higher-frequency bands, in this case the `VHF` band.~ Electrical drawings (schematics) show an inductor (a coil) as several half- circles drawn side-by-side (as a picture of the turns of wire in a real coil). If a line ending in an arrow is drawn through the coil, this means it's an `adjustable inductor`, just like `symbol B`.~ If capacitors are `connected in parallel`, their capacitances add together. So, if `two equal-value capacitors` are `connected in parallel`, then their two equal capacitance values would add up to `twice the value` of one capacitor.~ C.You must monitor and supervise the communication only if contacts are made on frequencies below 30 MHz~ When warm, dry air in the lower atmosphere (the troposphere) moves over cold, moist air, sometimes a "waveguide" for VHF and UHF signals is created, called `tropospheric ducting`. The `weather condition` which is best for `tropospheric ducting` is a stable or slow-moving `high pressure system`.~ Which operator licenses authorize privileges on `446.0 MHz`?~ B.To the side of the `power transformer's primary winding that does not have a fuse`~ D.100 watts~ D.See if a third station can clearly receive both of you~ What is the meaning of: "Your signal is `full quieting`..."?~ D.The resistance material~ B.A certificate from an instructor showing that you have attended a class in HF communications~ In a DC circuit, the flow of electrons is called an electric current. A pressure called voltage forces electrons through the `resistance` of the circuit. Ohm's Law says that voltage = current times `resistance` (abbreviated E = I x R). When `voltage and current are known`, `resistance` is `calculated` by dividing voltage by current: `R = E / I`.~ The wires in a three-wire AC line cord are color coded for safety. The black (or red) wire goes to the fuse, the `white wire` goes to the `power transformer's primary winding that does not have a fuse`, and the green wire goes to the chassis for a ground.~ D.Dawn~ An unchanging RF signal is called an RF carrier. By itself, it's not too useful, so it's usually made to carry some type of `modulation` `to send information` such as a voice. This is done by `varying a radio wave`. For instance if a radio wave's frequency is varied in time with the changes in an audio signal (a voice), this is called frequency `modulation` (FM).~ A.A calibrated voltmeter~ When may you send `profane words` from your amateur station?~ B.Watch out for loose `jewelry contacting high voltage`~ A.`30 volts`~ directional wattmeter, forward and reflected power~ B.There are fewer transmitters operating in this range~ C.`I = E / R` [current equals voltage divided by resistance]~ C.A low-pass filter~ B.To reduce output power~ A station in `beacon operation` sends out a signal that other people on the band can hear if propagation is good to the beacon station's location.

This isn't as bad as it seems because `model craft` signals are always used for short-distance work, and a big signal just isn't needed.~ With automotive wiring (not house wiring!), it's a good idea to put `fuses` for a `transceiver's DC power cable` `in series` with both the `red and black wires`. That way if the starter has a bad ground connection and tries to draw lots of current through the transceiver's ground connection, the `fuses` will blow instead of destroying the transceiver.~ A.Symbol A~ C.An antenna where all elements are driven by direct connection to the feed line~ D.Extra, Advanced only~ In Figure T6-1 which symbol represents an `adjustable inductor`?~ B.Symbol B~ A.`2.5 mA`~ bandwidth, single-sideband, between 2 and 3 kHz~ capacitance of a capacitor, material, area, number of plates, spacing~ C.`Two or more conductive plates` with an `insulating material between` them~ B.Only when they are not retransmitted through a repeater~ What is a repeater called which is `available for anyone` to use?~ D.It produces genetic changes in the tissue~ Electrical energy flowing one way into a `capacitor` is stored. If the flow stops, the stored energy can flow the other way. The energy is stored in `two or more conductive plates` which are usually very close together but don't touch each other because of an `insulating material between` them.~ D.Morse code practice~ C.`92 watts`~ D.The metal tool can pick up enough magnetic energy to become a shock hazard~ D.`In series` with both the `red and black wires`~ QSO, a conversation~ antenna, portable HF, dipole~ What does `standing-wave ratio` mean?~ Why would you use a `dummy antenna`?~ Which `tolerance rating` would a `high-quality resistor` have?~ What other emission does `phase modulation` most `resemble`?~ When we talk about an antenna's electromagnetic-wave `polarization`, we mean which way the electric lines of force of its radio energy are pointing. A `Yagi antenna` sends out radio energy polarized in the same direction as its elements.

A `3-30 MHz RF power meter` which is accurate in the HF bands `will not be accurate` at all if it is used at `VHF` frequencies (30 to 300 MHz).~ A repeater listens for signals on its input frequency and retransmits them more powerfully on its output frequency. The difference between the output and input frequencies, (called the "offset" or the `input/output frequency separation`), is `600 kHz` for the `2-meter band`.~ B.Both repeater licensees~ The ionosphere bends signals differently depending upon their frequency and how much `ultraviolet radiation` is received from the sun. The `maximum usable frequency` of signals which are bent back to earth changes because the amount of the sun's `radiation` changes all the time.~ D.It causes interference to other stations near the transmitting frequency~ As you might expect, you'll want to use a `dummy antenna` rated at `100 watts continuous` duty for off-the-air testing of a `100-watt single-sideband phone` transmitter.~ C.To keep them from getting stuck in place~ C.The same as the value of either inductor~ D.A subcarrier~ C.1.6 MHz~ C.The metal tool can pick up enough magnetic energy to become very hot~ If the FCC rules say that the amateur service is a `secondary user` of a frequency band, and another service is a primary user, what does this mean?~ D.`5.0 MHz`~ Each element of a `cubical quad` antenna is a four-sided square wire loop about `one-electrical wavelength` long ("quad" means "four-sided" in this case). Two or more of these loops are lined up in parallel with each other, making the antenna look something like a cube.

If the electrical energy stops flowing, the `electric field` flows back through the capacitor as electrical energy flowing the other way. All capacitors `store energy` in an `electric field`. This is called `capacitance`.~ A.Only when they do not cause interference to other communications~ One type of emission with `high-fidelity audio` and little static is `FM voice`. `Even when the signal is somewhat weak` it can be understood clearly. However, it needs a wide bandwidth, so it's not used below 29 MHz.

When `voltage and current` are known, `calculate` `resistance` by dividing voltage by current: R = E / I.~ A `dummy antenna` is a nonradiating load for a transmitter made up of a noninductive resistor, usually surrounded by a cooling liquid. Because a `dummy antenna` `changes RF energy into heat` instead of radio waves, it will get `warm when in use`.~ What is one reason for using `tactical call signs` such as "command post" or "weather center" `during an emergency`?~ What is a `dummy antenna`?~ D.The material between the plates, the area of one plate, the number of plates and the material used for the protective coating~ A.To reduce RF energy below a cutoff point~ A.Amplitude modulation~ What causes `splatter interference`?~ directional antenna, radio energy, one direction~ B.The power radiated from the top of an antenna system~ A.0.25 ohm~ If you are a `Technician` licensee, what must you have to prove that you are authorized to use the Novice amateur frequencies `below 30 MHz`?~ D.When a temperature inversion occurs~ A movable ferrite core is put into a coil to `change the coil's inductance`. To `tune a ferrite-core coil`, the core is moved up or down until the coil has the right inductance. If you put a `metal tool` down inside the coil to move the core, the metal in the tool will `change the coil's inductance` just like the core and you won't tune the coil right.~ If electrical energy flows one way through an inductor (a coil), a `magnetic field` is built up around it. If the electrical energy stops flowing, the `magnetic field` falls back through the inductor and generates electrical energy. All inductors can `store energy` in a `magnetic field`. This is called `inductance`.~ D.A radio control station~ A.600 kHz~ `Primary service` stations "own" the bands they are on. Secondary stations may use the same band as long as they don't interfere.

If the antenna's impedance doesn't exactly match the impedance of its feed line, some of the radio energy sent to the antenna will reflect back down the feed line. `Forward power` is the amount of radio energy sent `from the transmitter to the antenna`, and doesn't count any reflected power.~ What are the `parasitic elements` of a `Yagi` antenna?~ D.146.0 - 147.0 MHz only~ 52.525 MHz, Technician~ RACES drills, civil defense organization~ The `visible horizon` for `VHF signals` means the large area around a transmitting antenna where its signals can be heard directly, without being reflected, ducted or bent. `Direct wave` propagation means a signal goes straight from the transmitting antenna to the receiving antenna.~ What does a `capacitor` do?~ C.It provides electrons by a chemical reaction~ 30 MHz to 300 MHz, ANSI RF protection guide, human body absorbs RF energy~ Which `tolerance rating` would a `low-quality resistor` have?~ transmitting antennas, no one can come near them~ maximum transmitter power, model craft, one watt~ B.The `electric lines of force` of a radio wave are `parallel` to the earth's surface~ C.Because contact might cause spurious emissions~ If two repeaters use the same frequency, (`one station recommended` by a frequency coordinator and the other `unrecommended`), and there is `interference` between the two, the operator of the `unrecommended` repeater is `responsible` for taking care of the `interference` to the `recommended` repeater.~ B.It decreases~ local, use VHF and UHF, minimize interference on HF~ dummy antenna, off-the-air transmitter testing~ What does `vertical wave polarization` mean?~ If a `magnetic-base whip` antenna is placed on the roof of a car, in what direction does it send out `radio energy`?~ What is the condition of the `ionosphere` just `before local sunrise`?~ C.A banana plug connector~ A.90 to 100 ohms~ C.It stays the same~ C.Ampere's law~ driven elements, beam antennas, one~ B.Two or more square or circular loops are fixed in line with each other~ A.An AGC circuit~ D.The ratio of `maximum to minimum voltages` on a feed line~ C.The E region is above the F region~ `52.525 MHz` is in the exciting 6-meter band, but you must have at least a `Technician` license to use it.

This means they can hear you perfectly without any background static or hissing in your signal.~ In Figure T6-1 which symbol represents an `electrolytic capacitor`?~ Any time you put up `transmitting antennas`, you'll want to make sure that `no one can come near them` when you're on the air. Touching an antenna while it is carrying high-power radio energy might cause RF burns or an electric shock.~ If two repeaters use the same frequency, (`both stations recommended` by a frequency coordinator), and there is `interference` between the two, then `both repeater licensees` must work together equally to solve the problem.~ C.HF~ On the `70 cm` band, RTTY or packet signals using experimental digital codes must stay within the `maximum authorized bandwidth` of `100 kHz`.

If you'd like to ask, "Is the `frequency is in use`?" when you're `on CW`, you'd send "`QRL`?" (with a question mark).

The parasitic elements reflect and focus `radio energy` in one direction, like a flashlight beam, so the antenna is called a `parasitic beam antenna`.~ A.300 bauds~ If you are operating simplex on a `repeater` frequency, why would it be good amateur practice to `change to another frequency`?~ What is a `cubical quad` antenna?~ C.A `noninductive resistor`~ C.An auxiliary station~ `Splatter interference` on nearby frequencies may be caused if too much audio signal is put into a transmitter, called `overmodulation`. If you transmit with your microphone gain set too high, the loudest sounds of your speech will cause your signal to spread out too much beyond your operating frequency and cause `splatter interference` to other stations.~ For RF safety, what is the best thing to do with your `transmitting antennas`?~ A repeater listens for signals on its input frequency and retransmits them more powerfully on its output frequency.

If `strong signals` are heard on the `10-meter band` from 500 to 600 miles away, this can mean that `long-range skip` may be occurring on the `6- meter and 2-meter bands`.~ Instead of perfectly bending a signal back to earth, the ionosphere will sometimes `scatter` a signal around a wide area. If part of this area is outside the signal's ground wave range but inside its sky-wave range (in a skip zone), a `weak and distorted signal` can sometimes be heard from the `scatter` propagation.~ What is the maximum number of `hours allowed per week` for `RACES drills`?~ C.70 centimeters~ C.40 A~ B.An RST meter~ The FCC rules for amateur radio say that reading the news, playing music, making announcements, etc. `may not be transmitted`.

This requires a `low-level signal` which is very `stable` and can be `set to a desired frequency`, the kind of signal that an RF `signal generator` produces.~ If you know the `voltage and current` supplied to a circuit, what formula would you use to `calculate` the circuit's `resistance`?~ A.LF~ C.`21.1 - 21.2 MHz`~ Which two daytime ionospheric regions `combine` into one region `at night`?~ C.The licensee of the recommended repeater~ ionosphere, solar radiation, outer atmosphere~ B.A quad antenna~ D.Watch out for sharp edges which may snag your clothing~ D.It reverses the sideband of the signal~ C.Increasing the power of a transmitter~ What determines the `capacitance of a capacitor`?~ Electrical energy flowing into a `capacitor` is stored `electrostatically` in two or more conductive plates separated by an insulating material. One plate loses electrons and the other plate gains electrons. This electrostatic charge `opposes a change in voltage`.~ A.When tropospheric ducting occurs~ If electrical current flows one way through an inductor (a coil), it stores energy in a magnetic field around the inductor. If the current stops, electrical energy is generated from the magnetic field. The ability to generate this electrical energy is called inductance.

A pressure called `voltage` forces electrons through the resistance of the circuit. Ohm's Law says that `voltage` = current times resistance (abbreviated E = I x R). When `current and resistance are known`, `voltage` is `calculated` by multiplying current by resistance: `E = I x R`.~ station identification, transmitter, model craft, name, address, call sign~ The name `RTTY` stands for "radio teletype", which is a way to send printed messages by direct-printing telegraphy.

Readability is a number from 1 to 5, (5 is the best). Signal strength is a number from 1 to 9, (9 is the best). So, if your signal report is `three three`, it means `readable with considerable difficulty` and `weak in strength`.~ What `weather condition` may cause `tropospheric ducting`?~ If warm, dry air in the lower atmosphere (the troposphere) moves over cold, moist air, this is called a `temperature inversion`. Sometimes this creates a "waveguide" for `VHF radio waves` which are `propagated several hundred miles` farther than normal.~ B.Once every ten minutes, and at the beginning and end of each transmission~ D.The electric and magnetic lines of force of a radio wave are parallel to the earth's surface~ ionospheric absorption, long wavelength, D region~ interference, NOT recommended either station, both repeater licensees~ If a `variable-frequency oscillator` is connected to a driver and a power amplifier, this will make a `VFO-controlled transmitter`. The `variable- frequency oscillator` (or VFO) will control the transmitter's frequency while the driver and power amplifier will boost the transmitted signal strength.~ D.The American National Standards Institute (`ANSI`)~ If you use a `3-30 MHz RF power meter` for `VHF`, how accurate will its readings be?~ D.Extra, Advanced, General, Technician, Novice~ What is the `maximum transmitter power` an amateur station is allowed when used for telecommand (control) of `model craft`?~ If a `radio-frequency signal` is sent without any modulation, the signal will not change at all (it will be `constant-amplitude`). This is called an `RF carrier` signal. By itself, it's not too useful, so an `RF carrier` is usually made to carry some type of modulation.~ B.D and E~ B.It stores a charge `electrostatically` and `opposes a change in voltage`~ D.The frequency coordinator~ D.An antenna which sends and receives radio energy equally well in two opposite directions~ Where should the `green wire` in a three-wire AC line cord be connected in a power supply?~ B.A crystal-controlled transmitter~ The `control point` is the place where the `control operator` supervises a station's transmissions. This could be somewhere far away if the station is remotely controlled, but wherever the `control operator` is in command, it's known as the `control point`.~ What is the proper `distress call` to use when `operating CW`?~ B.Connect a `terminal-node-controller` to the transceiver's `microphone input`~ D.By adding `resistance in parallel with the meter`~ D.The FCC `rules do not specify` a maximum frequency shift above 50 MHz~ C.To better conduct current~ D.An operating schedule for authorized amateur emergency stations~ C.`To the chassis`~ D.An SSB meter~ What `two sub-regions` of ionosphere exist only in the `daytime`?~ B.`Out-of-channel emissions`~ C.Extra, Advanced, General only~ A.They `pass through` the `ionosphere`~ B.The brain~ D.They will be accurate providing the readings are multiplied by 4.5~ D.Wait for a few minutes to see if the person can get away from the high voltage on their own, then try to help~ C.`100 kHz`~ Voice signal reports are given with two numbers, readability and signal strength. Readability is a number from 1 to 5, (5 is the best). Signal strength is a number from 1 to 9, (9 is the best). So, if your signal report is `five seven`, it means `perfectly readable` and `moderately strong`.~ C.Two or more square or circular loops are stacked inside each other~ D.By adding resistance in parallel with the meter, between the meter and the circuit under test~ B.141 watts continuous~ Which of the following are `common resistor types`?~ A.`In series with the circuit`~ Not all the bands we hams are allowed to use belong just to the amateur service. On some bands, we amateurs are a `secondary user`, which means we must `not cause harmful interference` to a primary user of the band (usually we just change frequencies so as not to interfere). Part 97.303 lists the bands where hams are the `secondary user`.~ A.Properly fill out `FCC Form 610` and send it to the FCC in `Gettysburg`, PA~ Stations in the Radio Amateur Civil Emergency Service (RACES) are allowed to have drills and tests on the air to help them practice for a real emergency. However, the most `hours allowed per week` for `RACES drills` is `one`.~ If you have an emergency and you need to make a `distress call` while `operating phone`, say the word "`MAYDAY`" several times. The word "`MAYDAY`" is recognized all over the world as a call for help when `operating phone`.~ A.An nondirectional transmitting antenna~ D.200 kHz~ C.By using Thevenin's theorem for resistors~ A.Say "break, break 79," then say the station's call sign~ D.You must pass a `Morse code test` (either Element 1A, 1B or 1C)~ B.Q signals~ C.`Midday`~ What is used to `measure relative signal strength` in a receiver?~ D.`VHF`~ If electrical current flows one way through an inductor (a coil), it stores energy in a magnetic field around the inductor. If the current stops, electrical energy is generated from the magnetic field. The ability to generate this electrical energy is called inductance. The `basic unit of inductance` is called the `henry`.~ electrolytic capacitor, symbol A~ D.52.0 - 54.0 MHz only~ B.Peak output power~ How is the `voltage` in a DC circuit `calculated` when the `current and resistance are known`?~ C.Tune to one of the frequencies of station `WWV or WWVH`~ adjustable inductor, symbol B~ D.Any `directors` or any `reflectors`~ D.Try to imitate the sound quality you are receiving~ When we talk about a wave's polarization, we always mean which way its `electric lines of force` are pointing. `Horizontal wave polarization` means that the wave's `electric lines of force` are pointing horizontally, or `parallel` to the surface of the earth.~ If inductors are `connected in series`, their inductances add together. So, if `two equal-value inductors` are `connected in series`, then their two equal inductance values would add up to `twice the value` of one inductor.~ absorbing radio signals, daytime, D region~ A.200 watts PEP output~ C.QRL?~ B.Current, resistance and power~ What is the proper way to ask someone their `location` when using a `repeater`?~ C.A vertical conductor 1/4-electrical wavelength high, fed at the bottom~ polarization, man-made electrical noise, vertical~ B.`Broadcasts` intended for the `general public`~ reflected power, returned to a transmitter from an antenna~ What type of beam antenna uses `two` or more `straight elements` arranged `in line` with each other?~ If `two equal-value capacitors` are `connected in series`, what is their total capacitance?~ phase modulation, resemble, frequency modulation~ A repeater (like all other amateur stations) must identify itself when on the air. If CW (Morse code) is used for `automatic identification`, the `fastest code speed` which can be used is `20 words per minute` (WPM). (Just remember it's the same code speed, `20 words per minute`, that's needed to earn an Extra class license.)~ B.A variable-frequency oscillator~ D.Write the FCC and report the closed condition~ B.They are `more efficient` and `help coordinate` public-service communications~ C.An F-type cable connector~ When may you send `indecent words` from your amateur station?~ iron core, inserted in a coil, inductance, increases~ D.Release of fluorocarbons into the atmosphere~ B.Retransmission by automatic means of programs or signals from non- amateur stations~ What causes the `ionosphere` to form?~ A.A band-pass filter~ frequency calibration signal, crystal calibrator~ There's no need for abbreviations or special Q signals when you're using a voice `repeater`.

So, if you want to measure current, use an `ammeter` `connected` `in series with the circuit`. Since the `ammeter` will be in series, the same current flowing through the circuit will flow through the `ammeter`.~ C.F1 region~ What `frequency standard` may be used to `calibrate the tuning dial` of a receiver?~ A.Keying a transmitter too fast~ D.`F2 region`~ D.Use more power~ Electrical drawings (schematics) show an `inductor` (a coil) as several half- circles drawn side-by-side (as a picture of the turns of wire in a real coil). If two solid lines are drawn next to the half-circles, this means it's an iron-core `inductor`. Since a coil wound on a `toroidal core` is a type of iron-core `inductor`, `symbol D` is correct.~ D.A `ground plane`~ A.The magnetic lines of force of a radio wave are parallel to the earth's surface~ B.Someone who provides advice on what kind of repeater to buy~ A.Signal loss is the same for any frequency~ A coil is a `number of turns of wire` wrapped around a `core material` which has a certain `length` and `diameter`. Changing the `core material`, the `number of turns of wire`, the `length` or the `diameter` of the coil will change its `inductance` (the ability of the coil to store energy in a magnetic field).~ B.It is more resistant to distortion caused by reflected signals~ An `RF signal generator` may be used when `aligning tuned circuits`, such as those in a receiver. This requires a low-level signal which is very stable, the kind of signal that an `RF signal generator` produces.~ D.The ohm~ C.144.0 - 148.0 MHz only~ What is the `maximum symbol rate` permitted for RTTY or data transmissions `between 50 and 222 MHz`?~ What circuit uses a `limiter` and a `frequency discriminator` to produce an audio signal?~ B.Approximately 10 amperes~ What device should be `connected to a transmitter's output` when you are making transmitter `adjustments`?~ A.1 kHz~ A.The `heart`~ A.Single-sideband phone~ sky-wave propagation, least often occur, VHF~ B.It gives `RF exposure limits` for the human body~ C.A `dipole`~ polarization, Yagi antenna, parallel, horizontal~ A.Take your shoes off~ B.Tesla's law~ Where should a `reflectometer` be connected for `best accuracy` when reading the impedance match between an antenna and its feed line?~ Technician, Morse code, 21.1 - 21.2 MHz~ two amateur stations, equal right to operate~ Special tones are used by a `terminal-node-controller` to send binary data over the air. If the audio output of a `terminal-node-controller` is connected to the `microphone input` of a transceiver, the tones will be transmitted instead of a voice. This is how `packet-radio emissions` are sent.~ B.The licensee of the repeater which has been recommended the most recently~ No matter what `language` you're speaking when on the air, when it comes to `identifying your station`, you must always use the `English language`.~ messages, well-being, health and welfare traffic~ What device can be installed to feed a `balanced antenna` with an `unbalanced feed line`?~ A.The F2 region~ 6-meter Yagi antenna, 150 feet from your transmitter, RG-213~ What document would you use to see if you comply with `standard electrical safety rules` when building an amateur antenna?~ `WWV and WWVH` are radio stations which broadcast on exact frequencies. You can use their signals to `check the accuracy` of a receiver's `tuning dial`. Just tune in WWV at, say, 10 MHz. If your `tuning dial` says 10.037 MHz, you know it's set 0.037 MHz (37 kHz) too high.~ C.The amount of `radiation` received from the sun, mainly `ultraviolet`~ C.Be certain all `amplifier shielding is fastened in place`~ A.A very low pressure area~ A.`0.1%`~ C.Electrolytic and metal-film~ A.A `balun`~ A.Remove all amplifier shielding to ensure maximum cooling~ B.The absence of signals on the 10-meter band~ B.It stores a charge electrochemically and opposes a change in current~ A.MAYDAY~ C.Parabolical~ C.`Ultraviolet`~ Once you have `opened a VHF power amplifier` for any reason, you should never give it power unless the `amplifier shielding is fastened in place`. The human body (especially the eyes) can easily be harmed by RF energy in the VHF range from an unshielded (open) VHF power amplifier.~ B.Low-power stations~ A.Choose an unoccupied frequency~ From the `narrowest bandwidth to the widest`, `CW` is the narrowest, since it's just on/off-keyed carrier. The binary data of `RTTY` needs just a small frequency shift, so it's next narrowest. The two voice modes have the widest bandwidths because a voice has mixed high and low frequencies. Telephone-quality `SSB voice` is narrower than high-fidelity `FM voice`.~ A.Ground-wave~ C.An autopatch repeater~ D.They absorb magnetic energy which makes them hot~ Which region of the ionosphere is mainly responsible for `absorbing radio signals` during the `daytime`?~ C.25 A~ A.Inductance~ C.An ionized path in the atmosphere where lightning has struck~ How can on-the-air `interference` be `minimized` during a lengthy transmitter testing or loading up procedure?~ B.Amateurs are only allowed to use the frequency band during emergencies~ B.To see if the receiving station operator is still awake~ What is a `repeater frequency coordinator`?~ D.Its resistance changes when it is heated~ C.`F1 and F2`~ Instead of switching an RF signal on and off to send Morse code, some transmitters send an RF signal which is modulated by an `on/off keyed audio tone`. This tone-modulated Morse code (called modulated CW, or `MCW`) acts just like Morse code sent by on/off keying of a transmitter's output.~ C.The `National Electrical Code`~ B.Symbol B~ Electrical drawings (schematics) show a capacitor as a straight line next to a curved line. If the symbol is for an `electrolytic capacitor`, the straight line will have a plus sign drawn next to it to show the capacitor's polarity. `Symbol A` shows an `electrolytic capacitor`.~ 12-volt, 0.15 ampere, 80 ohms~ Most modern receivers can receive many emission types, such as AM, FM, SSB, CW, etc. `Some emission types need a wider bandwidth` than others, so `several IF filters` are needed for different emissions. For instance, a narrow CW filter might have a 250 Hz bandwidth, while 2.4 kHz would be used for SSB, and somewhere around 12 kHz would be useful for FM.~ A.By feeding a microphone's audio signal into an FM transmitter~ As the plate `area` of a capacitor is `increased`, what happens to its `capacitance`?~ A.QSL?~ C.100 ohms~ balanced antenna, unbalanced feed line, balun~ B.Two or more `parallel four-sided wire loops`, each approximately `one- electrical wavelength` long~ B.A large copper ring or wire loop, used in direction finding~ C.Between 3 and 6 kHz~ unmodulated carrier wave, test~ B.RG-58~ A.It decreases~ B.MF~ C.Lightning ionizing the outer atmosphere~ Ohm's Law says that voltage = current times resistance (abbreviated E = I x R). When voltage and resistance are known, current is calculated by dividing voltage by resistance: I = E / R. So, if a `48000-ohm` resistor is connected to `12 volts`, the current flow will be 12 / 48000 or 0.00025 amperes (`250 uA`).~ The sun's radiation causes ionization of the `ionosphere`.

Of course, with a power limit of one watt for `model craft` signals, it probably won't interfere with anyone anyway.~ Each element of a `delta loop` antenna is a triangular wire loop about one- electrical wavelength long (the triangular loop looks like the Greek letter "delta"). Two or more of these `triangular elements` are lined up in parallel with each other to focus radio energy in one direction.

The higher the frequency, the less bending. The `maximum usable frequency` is the `highest frequency` signal that is bent enough to return to earth and `reach its intended destination` instead of passing through the ionosphere.~ ionosphere, least ionized, before dawn~ The `National Electrical Code` is a book of `standard electrical safety rules` for all kinds of electrical wiring, including amateur antennas. Although the Code is not a set of laws which must be obeyed, most cities use it when they write their own electrical safety regulations.~ RF radiation is similar to microwave oven radiation. If body tissues are exposed to `RF energy`, the energy `heats the tissue`. Large amounts of `RF energy` may cause RF burns. Of all your body parts, your eyes are the most likely to be damaged by RF radiation.~ A `repeater` listens for signals on its input frequency and retransmits them more powerfully on its output frequency.

When a repeater is `available for anyone` to use, it's called an `open repeater`.~ A.QRV?~ B.Extra, Advanced, General, `Technician` only~ When a resistor resists current flow, it loses electrical energy in the form of heat. If a `large size resistor` is used `instead of a smaller one`, more heat can be lost without burning up the resistor. This means that a large resistor has a `greater power dissipation` than a smaller resistor of the same resistance value.~ A.A `band-pass filter`~ The letters "BNC" stand for "Baby N Connector". The `BNC connector` is used for low-power RF connections in the VHF/UHF frequency range.

During `rush hours` emergencies can occur. If `repeater operation` is tied up with `third-party` communications nets, an emergency signal can't get through. This kind of `third-party` operation is `discouraged` during `rush hours`.~ B.2 kHz~ B.The lowest frequency signal that will reach its intended destination~ A.The A region~ An unchanging RF signal is called an `unmodulated carrier`. If an RF carrier's frequency is varied in time with the changes in an audio signal (a voice), this is called frequency modulation (`FM`). If an `FM` transmitter's `microphone failed to work`, its RF signal would not change, and it would produce just an `unmodulated carrier`.~ The name `CW` stands for "continuous wave", which means just a plain RF signal which is started and stopped by switching a `transmitter's output on and off`. A special on/off code called international `Morse code` is known all over the world as the best way to send the letters, numbers and punctuation of messages by `CW`.~ D.Ground-wave~ B.E region~ What are the possible values of a `100-ohm resistor` with a `10% tolerance`?~ What is the usual `bandwidth` of a `single-sideband` amateur signal?~ C.Highway traffic information nets~ B.1.0 MHz~ When a contact is possible between two hams who can receive each other's signals, `simplex` operation should be used instead of a repeater. (Both hams move to a different frequency and take turns talking.) That way the `repeater will not be tied up` and may be used by someone who might need it for an emergency.~ renew or change, FCC Form 610, Gettysburg~ What is a `henry`?~ blocks RF energy, above and below a certain limit, band-pass filter~ 4800-ohm, 12 volts, 2.5 mA~ In an electric circuit, the flow of electrons is called an electric `current`. A pressure called `voltage` forces electrons through the `resistance` of the circuit. A formula known as `Ohm's Law` says that the `voltage` of a circuit equals the `current` flowing multiplied by the `resistance` (`voltage` = `current` times `resistance`, abbreviated E=IR).~ ANSI RF protection guide, RF exposure limits~ What is the `maximum frequency shift` permitted for `RTTY or data` transmissions `below 50 MHz`?~ C.You must attend a class to learn about HF communications~ B.It causes them to travel shorter distances~ C.Extra, Advanced, General only~ A.There are more transmitters operating in this range~ What does `reflected power` mean?~ D.An `FM receiver`~ Ohm's Law says that voltage = current times resistance (abbreviated E = I x R). When voltage and current are known, resistance is calculated by dividing voltage by current: R = E / I. So, if a `12-volt` battery is supplying a `0.15 ampere` current to a circuit, the circuit's resistance must be 12 / 0.15, or `80 ohms`.~ According to the `ANSI RF protection guide`, what is the `maximum safe power` output to the antenna of a hand held `VHF or UHF` radio?~ What is an `RF signal generator` used for?~ Which operator licenses authorize privileges on `52.525 MHz`?~ B.The power `returned to a transmitter from an antenna`~ D.`VHF`~ What is the ability to `store energy` in a `magnetic field` called?~ voltmeter, lower to a higher, range, resistance is added in series~ A.The value of the resistor in ohms~ D.A rectifier modulator~ input/output frequency separation, 2-meter band, 600 kHz~ D.An antenna where the driven element obtains its radio energy by induction or radiation from director elements~ The American National Standards Institute (ANSI) has studied the effects of RF energy on the human body. They publish the `ANSI RF protection guide` which says that `7 watts` is the `maximum safe power` output for a `VHF or UHF` hand held radio.~ A.Those which are necessary to meet `essential communication needs` and facilitate `relief actions`~ An `FM` transmitter may cause interference to other stations near its frequency channel (`out-of-channel emissions`) if too much audio is used to modulate its signal. This `overdeviation` may be caused by talking too loud or too close to the microphone.~ `During an emergency` it's `more efficient` to use simple names (called `tactical call signs`) instead of amateur call signs when you need to talk to special stations (such as the "command post"). `Tactical call signs` also `help coordinate` communications with other public-service units which may not be familiar with amateur call signs.~ A.RTTY, CW, SSB voice, FM voice~ C.Two~ C.By using Thevenin's theorem for resistors~ D.Station identification is not required if the transmitter is labeled with the station licensee's `name`, `address` and `call sign`~ What is the name of the area that makes `long-distance radio communications` possible by `bending` radio waves?~ A.To the fuse~ B.As amateur traffic~ Why is the limit of exposure to RF the lowest in the frequency range of `30 MHz to 300 MHz`, according to the `ANSI RF protection guide`?~ C.An antenna which sends and receives `radio energy` mainly in `one direction`~ What is the proper way to `break into a conversation` on a repeater?~ The sun's radiation causes ionization of the ionosphere. The `E region` is ionized enough to bend radio waves only during the day. Once the sun comes up in the morning, ionization increases until the sun is high overhead. So, at `midday` the `E region` is the `most ionized`.~ B.The `basic unit of capacitance`~ D.`Symbol D`~ C.Connect a keyboard to the transceiver's microphone input~ D.`Ionization is at a minimum`~ precaution, over a power amplifier, jewelry contacting high voltage~ C.A sound used to indicate that a message is waiting for someone~ Which region of the ionosphere is mainly responsible for `long-distance sky- wave` radio communications?~ A.CW~ parasitic elements, Yagi, directors, reflectors~ B.A repeater~ safety rule, main electrical box, how to shut off the electricity~ D.The place inside an inductor where its `magnetic field is concentrated`~ C.Because HF transmissions are not propagated locally~ If you want to give someone a `signal report` when you're talking on a `repeater`, just tell them how much `quieting` their signal has into the `repeater`. For instance, for a perfect signal, you'd say "full `quieting`".~ Figure T7-3, FM receiver~ C.Hotter circuit components nearby heat them up~ C.A wavemeter~ If you have a Novice license and you have a `CSCE` `for Technician`, you may use Technician frequencies (in this case `146.34 MHz`).
