When you feel confident with the material, proceed to try a practice exam. There are several sites you can use to take a full practice test, including HamStudy.org, HamExam.org, and AA9PW.com.
A Volunteer Frequency Coordinator recognized by local amateurs (T1A08) is a local or regional entity that recommends frequencies and channels for repeater stations to avoid such interference.
The Radio Amateur Civil Emergency Service (RACES) is a radio service using amateur frequencies for emergency management or civil defense communications (T1A10).
On HF (below 30 MHz), the use of phone (voice) is allowed for Technicians on the 10 meter band only (T1B06), in the 28.300 MHz to 28.500 MHz (T1B01) segment of the band. Also on 10 meters, Technicians may only use single sideband (SSB) for voice communications. Other modes such as FM (frequency modulation) or AM (amplitude modulation) are not allowed on 10 meters for Technicians.
A club can be as large as the American Radio Relay League (ARRL)—it has approximately 160,000 members—or as small as four people, the minimum FCC requirement.

The sideband that is lower in frequency than the carrier is called the lower sideband (LSB). The sideband that is higher in frequency than the carrier is called the upper sideband (USB). In amateur radio, the convention is that for SSB, lower sideband is used from 7 MHz and below. Upper sideband (T8A06) is used from 14 MHz and up, including 10 meter HF, VHF, and UHF. Many modern radios automatically follow this convention. You can still legally use either sideband (except on the 60 meter band—5 channels between 5.330 MHz to 5.406 MHz where you must use USB), but be careful not to interfere

For example, the 2 meter band is “V” and the 70 centimeter band is “U.” So in the case of a satellite that is operating in U/V mode, the uplink is in the 70 centimeter band and the downlink is in the 2 meter band (T8B08).
A power increase from 20 watts to 200 watts is 10 dB (T5B11). This is ten times the power.
Capacitance and inductance both describe the ability to store energy in a circuit. Capacitance (T5C01) is the ability to store energy in an electric field, and inductance (T5C03) is the ability to store energy in a magnetic field.
How to Draw a Radio Circuit
Lightning protection consists of three things: grounding, bonding, and lightning arresters. Lightning arresters are either gas discharge tubes or semiconductor devices called MOVs (metal oxide varistors). Both devices shunt (shift or divert) the lightning discharge to ground, away from your equipment. Install them on a grounded panel near where feed lines enter the building (T0A07).
Which of the following could be the reason you are unable to access a repeater whose output you can hear? A. Improper transceiver offset B. You are using the wrong CTCSS tone C. You are using the wrong DCS code D. All these choices are correct
What type of signaling uses pairs of audio tones? A. DTMF
