NCVEC 2023–2027 General pool (423 questions), valid through June 30, 2027

About

The General license adds most of the HF bands to a Technician’s privileges, including long-distance voice and data. The exam’s 35 questions come from the public pool maintained by the NCVEC Question Pool Committee.

Ham General Prep covers that pool with lessons, explanations, and drills, and adds working tools for the parts of the exam that are easier to understand by trying them: propagation, antennas and feed lines, RF exposure, and modulation. The current pool expires on June 30, 2027; the app will be updated for the pool that replaces it.

Planned features

Intended scope. Subject to change before release.

A lesson for every question group
35 lessons, each followed by practice on that group's questions.
Explanations for every question
Why the correct answer is correct, and why each other option is not.
Practice exams drawn like the real one
One question from each of the 35 groups, 26 to pass, with a review of every miss.
Propagation model
A teaching model of the maximum and lowest usable frequencies by hour, season, solar flux, and K index, showing which bands open and why.
Antenna, feed line, RF exposure, and signals tools
Antenna lengths and coax loss, the FCC's RF exposure limits worked out step by step, and AM, SSB, and FM waveforms and spectra.
Math drills
Antenna lengths, decibels, power, RMS and PEP, transformers, SWR, and FM deviation, with worked solutions.
Works offline
All study material is on the device.

Planned pricing

Free to download. The first sections and one practice exam are free; a one-time purchase unlocks the rest.
