It's like that here in SC with the WHRI transmitters... not real far
away but a hard catch, especially at night.

That's because of the skip zones of HF frequencies. Unlike BCB, there is
very little ground wave on most of HF, it's all skywave, and the skip zone
starts very close to the transmitter.
