General Class License: The Upgrade That Opens Worldwide HF

If the Technician license is the door, General is the room. It is the upgrade that opens the shortwave bands where a hundred watts and a wire in a tree reach another continent on a weekday evening, and it is the reason experienced operators tell every new Technician to book the next exam immediately. The gap in capability between Technician and General is larger than the gap between General and Amateur Extra by a wide margin.

What the General license grants

A General may transmit on every amateur band allocated in the United States. What distinguishes it from Amateur Extra is a set of narrow exclusive slices at the bottom of four HF bands, and nothing else. What distinguishes it from Technician is nearly the whole of HF.

Read the right-hand column. On 160, 60, 30, 20, 17 and 12 metres a Technician has nothing at all, and on 80, 40 and 15 metres a Technician has a Morse-only sliver. General opens all of it, including the voice segments, at the full 1500 watt limit rather than 200 watts. The 20 metre band alone is worth the exam: it is the band that carries worldwide daytime contacts through every part of the solar cycle, and a half-wave dipole for it is 33 feet of wire that fits most yards.

What is on the exam

The General pool is organised into ten subelements with a fixed number of questions drawn from each. The distribution has shifted the weight away from rules and towards operating practice, propagation and antennas, which is a fair reflection of what actually changes when you gain HF privileges.

Antennas and feed lines is worth four questions, propagation three, and electrical principles three, and those ten questions are where the exam separates people who understood the material from people who memorised letters. If you can explain why a dipole at a quarter wavelength above ground is a regional antenna and the same dipole at a full wavelength works DX, you have already answered several of them. That specific point is worked through on the antenna height calculator.

The four topics that carry the most weight

Propagation. The ionosphere refracts HF signals back to earth, and which layer does it, at what frequency, at what time of day, is the whole subject. The practical version: the low bands work at night and over regional distances, the high bands work in daylight and over intercontinental distances, and the maximum usable frequency rises and falls with the eleven year sunspot cycle. Everything else is detail. Worked through properly on HF propagation basics.

Impedance and resonance. Reactance cancels at resonance, leaving resistance. That single sentence answers a surprising number of questions in G5. The exam wants you to know that inductive and capacitive reactance move in opposite directions with frequency, that they cancel at one point, and that a tuner does not make an antenna resonant, it makes the radio see a load it can drive.

Feedlines and SWR. Standing wave ratio is the ratio of forward to reflected voltage, high SWR increases loss in the line rather than damaging the antenna, and loss rises with frequency and with line length. The SWR calculator and the coax loss calculator cover the arithmetic behind every question in this group.

Single sideband operating practice. Upper sideband above 10 MHz and on 60 metres, lower sideband below 10 MHz, by convention rather than by rule. Bandwidth about 3 kHz. Speech processing raises average power and therefore average RF exposure. These are facts to know rather than concepts to derive.

How to study for it

Twenty to thirty hours is the working figure, and the method that fails here is the one that worked for Technician. Drilling 432 questions until the answer letters look familiar will pass the exam and will leave you unable to diagnose a high SWR reading or choose between two antennas, which is exactly what a new General needs to do in the first week.

1. Read the manual properly this time. The ARRL General Class License Manual$32.95 is written to be read rather than skimmed, and the propagation and antenna chapters are the ones to slow down on.
2. Build or model an antenna while you study. Nothing fixes the resonance, impedance and SWR material like cutting a dipole with the dipole length calculator and watching where the dip actually lands.
3. Drill by subelement, hardest first. G3 propagation, G5 electrical principles and G9 antennas together are ten questions. Get those to 90 percent before touching the rules sections, which are quick wins you can pick up in an evening.
4. Sit full randomised exams cold. Three consecutive fresh sets above 85 percent is the standard to book the session on.
5. Consider attempting Extra on the same day. Most people will not pass it without separate study, but the attempt is usually free and costs an hour.

The station to build once you hold it

A General license without an HF antenna is a General license that behaves like a Technician license. The order to spend money in, and it is not the order most people choose, is antenna first, feedline second, radio third.

• The radio. The Yaesu FT-891$769.95 is the standard first HF transceiver because it does 100 watts on every HF band plus 6 metres and works as happily in a car as on a desk. The Icom IC-7300$1,255.74 costs more and adds a real-time spectrum scope, which changes how you find contacts rather than how well you make them. Full field on best HF transceivers for beginners.
• The antenna. An end fed half wave such as the JYR8010 8-band end fed half wave, 150 W$89.99 needs one support and a ground-level feedpoint, which is why it beats a dipole on a small lot. A dipole is cheaper and quieter if you have two supports. Compare them on dipole versus end fed half wave.
• The feedline. MOOKEERF RG-213 coax, 100 ft with UHF male$115.99 for a permanent HF run. Loss on HF is modest, so the reason to buy good coax is power handling and weather survival rather than decibels.
• The power supply. A 100 watt radio draws about 22 amps on transmit, so a Powerwerx SS-30DV desktop power supply$164.17 at 30 amps is the right size. Sizing arithmetic on the power supply calculator.
• The tuner. An LDG Z-11ProII automatic antenna tuner$225.44 or similar, because a single wire antenna will not present 50 ohms on every band you now hold.

Assembled with grounding, connectors and lightning protection, that is the $2,017 first HF station.

Should you go straight on to Extra?

For most people, not immediately. The General license grants access to every band; Extra grants access to narrow exclusive segments within four of them. That is genuinely valuable if you chase rare DX, where the expedition station listening at 14.020 MHz is outside General privileges and the pile-up is thinner because of it. It is close to irrelevant if you work nets, ragchew, run digital modes or activate parks.

The other reason to upgrade is that the Extra pool is the best structured electronics education in the hobby, and passing it leaves you able to read a schematic, calculate a matching network and understand what your own equipment is doing. That is a real argument, and it is a different argument from the privileges. Both are laid out on the Amateur Extra page.
