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.

Terrain is generally quite flat between me and all the received nodes and it only happens at night. So ducting may be possible because the ocean is quite nearby on both the transmitter side and the receiver. I initially dismissed ducting just because of the fact that it's January and four in the morning.
