How is that even fucking possible? (lemmy.zip)

Last night, my node showed that it received information from a node 100 miles away, and I dismissed it as just a weird artifact. But tonight, my node is showing that there are three nodes that are around 220 miles away. I do not have MQTT enabled on downlink so they are definitely over RF. But how is that even fucking possible? I live in an area where the mesh is not super well built up and there are only a few people locally that have nodes and I would expect to get nodes from a lot closer than 200 miles away or even 100 miles away considering there are two decently large cities only 70 miles away. Also, so far I have only gotten these messages at night.

Edit: Correction, they are between 270 and 320 miles away.

That's a good point, but the only getting the messages at night lines up with previous reporting on ionosphere bouncing.

220 miles is not direct line of sight, at that point you have to bounce off of something

I dismissed it last night as an artifact because it was only one single node. But tonight I can't dismiss it because it's three of them. And they all show as either two or three hops away.

Edit: I stand corrected. They are between 270 and 320 miles away. And I thought it might have something to do with a heat inversion, but it's the middle of January. I wouldn't think that would be the cause.
