Block diagrams, oscillators, mixers, amplifiers and amplifier classes, AM, FM and SSB modulation, basic digital modes, AGC, ALC, and superheterodyne stages.

Feedlines, characteristic impedance, SWR, impedance matching and baluns, dipole, vertical and Yagi antennas, antenna gain, and radiation patterns.

HF, VHF and UHF propagation, ionospheric layers, MUF and critical frequency, ground wave, skywave, fading, sporadic E, and the solar cycle.

Causes of interference, harmonics and spurious emissions, filtering, ferrites, breakthrough, splatter, intermodulation, and electromagnetic compatibility.

Electrical safety, earthing, fuses, capacitor discharge, RF exposure limits, and antenna and mast erection safety near power lines.

Multimeter use for voltage, current and resistance, SWR meters, power and PEP measurement, frequency counters, and dummy loads.
