The best radio days start a little chaotic: rain on the windshield, a wire tossed higher than your plan, and a stranger asking, “What are you doing?” That moment led us into a POTA run where 10 and 15 meters opened like a faucet—France, Belgium, Spain, Germany—flowing in with the kind of clarity that makes you forget your battery just died mid-CQ. We break down why fall propagation favors 10/12/15/17, what to watch for when the D-layer calms down, and how “angry Sun” forecasts can still set you up for unforgettable runs.

We also put our study hats on. Todd faces three Extra-level questions—FST4’s full feature set, why CMOS sips power compared to Schottky TTL, and the hard boundary for spread spectrum above 222 MHz—and we unpack the why, not just the right letter. If you’re chasing your upgrade, you’ll leave with sticky memory hooks and real-world context you can use at the bench and in the field.
