Oats at from the land of the fair and wonderful (J/land, of course) but sold by an incoming fine establishment..
Grey Line.. much easier than me trying to hurt my mind at this time.
In ham radio refers to the twilight zone seperating daylight and darkness, which acts as a powerful, temporary enhancement for long-distance (DX) HF communication at dawn and dusk. During this time, the D layer of the ionosphere dissipates, eliminating signal absorption, while the F layer remains ionized, allowing for low-loss, worldwide skip propagation.
- When It Happens: Occurs roughly 30-60 minutes before and after local sunrise and sunset.
- Why It Works: The "terminator" (line between day/night) has low atmospheric interference, enabling signals to travel along it with less energy absorption.
- Best Bands: It is most effective for lower HF frequencies, specifically 160m, 80m, and 40m, though it can affect 30m and 20m as well.
- Directionality: Signals tend to propagate along the line of the terminator, allowing for strong signals to locations otherwise unreachable.
- Usage: It is often used for "Super DX" contacts, with many operators using software like WSPR or FT8 to exploit these times.
Prints all doing well.. I ordered a spare PEI plate
