Gear
Amateur radio equipment notes: choosing a radio for your license class, planning antennas and installations, and keeping a station clean and safe. The station page is what I actually run; the guides are research notes checked against Part 97.
Gear guides & my station
Handheld, mobile, or HF base: what each format is for, what your license class lets you use, and what to budget beyond the radio.
VHF/UHF HTs: bands and modes, antenna connectors, batteries, programming, and why a clean signal is the operator's responsibility.
Vehicle and desk installs: 13.8 V power, fusing, antennas and feed line, and RF exposure checks.
Dipoles, verticals, end-feds, and mobile whips; gain in dBi versus dBd; SWR and what it does not tell you; calculating coax loss.
