Even with S-7 noise, from here in Southern Nevada, picked up stations in Canada, Texas and Louisiana. Built to plans, except the PTO coil form was fabricated from a clothes hanger tube mounted in a fiberglass frame. Antenna is an inverted \u201cV\u201d. A ham since 2017, I\u2019m always looking for something to build, and the Soldersmoke podcast provided an educational and appropriately challenging project. I particularly like the fact it is modular, and I\u2019ve already identified other applications for the audio amplifier. Your guidance was excellent and I learned a bunch.
