TECHNICIAN FOUNDATIONS // V0.1
Labs
Eight foundation labs, eight Technician Core labs, then the remediation labs that are open. Finishing a set is not Technician exam readiness. The coverage audit is a historical record, not a score that later labs rewrite.
-
01
What Is Radio?
Explore frequency, wavelength, signals, noise, Hz/kHz/MHz, and basic receiver behavior.
NOT STARTED
-
02
Your First Radio
Frequency selection, volume, squelch, simplex operation, memories, and basic radio controls.
NOT STARTED
-
03
Repeaters
Repeater input/output frequencies, offsets, tones, range, and basic repeater operation.
NOT STARTED
-
04
Bands & Privileges
Amateur bands, Technician privileges, operating scenarios, and choosing an appropriate frequency.
NOT STARTED
-
05
Electricity Without the Textbook
Voltage, current, resistance, power, and an interactive introduction to Ohm's law.
NOT STARTED
-
06
Antennas & SWR
Frequency, wavelength, antenna length, resonance, SWR, and troubleshooting.
NOT STARTED
-
07
Propagation & Range
Line of sight, terrain, antenna height, VHF/UHF behavior, introductory HF propagation, and repeaters.
NOT STARTED
-
08
First Field Operation
An integrated scenario: choose equipment, frequency and band, antenna, operating method, and proper procedure.
NOT STARTED
Technician Core
TC-01 through TC-08 can be opened. They build on Foundations. Completing a core lab is not concept mastery, and it is not exam readiness.
-
TC-01
Your License & Responsibilities
What a Technician license allows and requires, practiced as operating decisions.
NOT STARTED
-
TC-02
Operating on the Air
Listening, calling, identifying, simplex, repeaters, and a first courteous contact.
NOT STARTED
-
TC-03
Components & Circuits
What common parts do, and how to read a basic schematic.
NOT STARTED
-
TC-04
Inside the Radio
Signal path, modulation, and a first troubleshooting sequence.
NOT STARTED
-
TC-05
Modes, Digital & Radio Activities
Receiver modes, occupied bandwidth, a digital path, and a simple satellite pass.
NOT STARTED
-
TC-06
Antenna Systems & Feed Lines
The path from the radio to the antenna, loss, polarization, and pattern.
NOT STARTED
-
TC-07
Measure, Test & Troubleshoot
Meters, a dummy load, and faults you isolate one measurement at a time.
NOT STARTED
-
TC-08
Safety, Emergencies & Responsible Operation
Site hazards, an educational exposure model, and emergency priority.
NOT STARTED
Technician Remediation
TR-01 through TR-09 can be opened. Completing the set is not concept mastery, not the historical coverage audit, and not exam readiness. Coverage verification comes next.
-
TR-01
Electrical Quantities & Circuit Math
Prefixes, decibel ratios, series and parallel resistance, and mixed voltage, current, and power decisions.
NOT STARTED
-
TR-02
Parts, Symbols & Practical Circuits
Parts and their jobs, the official schematic figures, a power-supply path, and solder-joint diagnosis.
NOT STARTED
-
TR-03
Rules as Operating Decisions
License, privilege, control, identification, and content decisions from a teaching reference, including a first week on the air.
NOT STARTED
-
TR-04
Repeaters, Nets & Public-Service Operating
CQ, repeater offsets including 70 centimeters, reverse, DTMF, DMR, nets, formal traffic, and ARES versus RACES.
NOT STARTED
-
TR-05
How Radio Waves Travel
Electric and magnetic fields, one free-space speed, the radio horizon, multipath, and the propagation paths beyond a first skywave sketch.
NOT STARTED
-
TR-06
Station Setup, Interference & Measurement
Station controls, mobile power, coax, SWR readings, receiver blocks, and an interference report handled with evidence.
NOT STARTED
-
TR-07
Modes, Satellites & Digital Activities
Mode bandwidth, upper and lower sideband, digital activities, fast-scan television, and a low-Earth-orbit pass.
NOT STARTED
-
TR-08
Antennas, Feed Lines & Connectors
Named antennas, a dipole pattern model, loading, feed-line loss, connectors, the tuner, and SWR.
NOT STARTED
-
TR-09
Safety Beyond the First Inspection
Electrical hazards, fuses, lightning bonding, tower decisions, and RF exposure factors. The exposure model is not a compliance calculator.
NOT STARTED
RF Labs
RF-01 is a supplemental simulation. It is not part of Technician Remediation, and it is not exam readiness. 0 of 1 complete.
-
RF-01
RF Interference & Jamming
What a receiver does when another signal or a raised noise floor competes with the signal you want. Simulation only.
