Portable Ham Radio Pack Calculator

Select components. Weight, estimated operation time, and range update live from the specs below — every number is sourced, and anything unsourced says so instead of guessing. Built from my own sourced working notes on each radio/antenna/battery. Work in progress — numbers are being actively checked and refined; if something looks off, it's a bad citation, not a guess.

Every spec on this page has an inline citation — if a number looks wrong, it's a bad citation, not a guess. This is still a work in progress; gaps are marked "needs data" rather than filled in with a guess.
