| | [AI summary] This document provides a detailed guide on constructing a magnetic loop antenna for shortwave radio listening. The process involves building the main loop, coupling loop, feedline, and tripod, along with tuning procedures and considerations for optimizing the antenna's performance. The loop is designed to reduce noise and improve reception, especially in noisy environments.

| A permanent magnet motor controller like moteus has to, at the end of the day, apply voltages to the phase wires of a motor in order to induce currents. Those currents generate magnetic fields that push against permanent magnets in the rotor to make the motor move. I've looked at parts of this process before,...
