What's on the Paper
- Licensing conditions and station identification: Licence scope and call signs, supervision, messages and encryption, interference and log keeping, remote operation, EMF assessments and Schedule 1.
- Operating practices and procedures: Calling CQ, call sign prefixes, Q codes and RST, logging in UTC, band plans, repeaters, digital voice, satellites, and operating abroad under CEPT.
- Technical aspects: Resistor networks, capacitors and inductors, time constants, reactance, sampling, transformers, tuned circuits and Q, transistors, oscillators and regulators, with resonance calculations.
- Transmitters and receivers: Modulation, transmitter block diagrams, DDS, SSB filters, PA linearity, key clicks, superhets, AGC, SDR and I/Q, and transverters, with image-frequency sums.
- Feeders and antennas: Feeder loss and velocity factor, baluns, polar diagrams and EIRP, traps, SWR and return loss, matching units and quarter-wave transformers, with ERP sums.
- Propagation: Sky waves and the D, E, F1 and F2 layers, polarisation, MUF and LUF, NVIS, sporadic E, moonbounce, aurora and link budgets.
- Electromagnetic compatibility: Blocking and cross-modulation, non-radio sources, routes of entry, image interference, filters, ferrites and braid breakers, antenna siting, vehicles and complaints.
- Safety: Mains plugs, fuses and RCBOs, live working, batteries, tools, ladders, lightning, portable operation, risk assessment and generators.
- Measurements and construction: Meter shunts and multipliers, PEP, SWR meters, oscilloscopes, spectrum analysers, decibels, the resistor colour code and soldering.
