Lot of good stuff in your response here, Brandon.

In regards to inversion, I’ve experienced from up on Flat Top. If I remember correctly, it was much warmer up high than in the town below. (May have been the opposite; memory fails me here.) I had difficulty with the local stations but I got a station way down on the peninsula (Kasilof) 5x9. It was as though signals were caught up high and just bounced around up there until they came out someplace else. It’s only happened once, though.

Others here know more about the Fairbanks - Anchorage VHF connection than I do, but I’ve been told the ham who did it lived above the Flat Top parking lot (there is a private neighborhood up there; DON’T go up there; the one guy is really territorial - threatened to call the police on me and report me as a sexual predator. True story.) anyway that ham was way high up and had a lot of power and I believe he was actually bouncing his signal off Mt. McKinley. That’s how I heard the story anyway. I’ll bet Ed tells it better than me.
