the Sierra de Bernia mountain range (maximum height of 1,100 meters)

I would love to make two-way radioamateur contacts from there. Probably the band noise is very low up there. And the propagation is very good there. This latter also depends on the nearby objects. For example I read that if there is a volcanic mountains nearby, the the propagation is very good on the 40 m (7 MHz) band in the evenings. The volcanic mountain acts as some kind of reflector. I do not know. I have not experienced this so far. I read this from someone a few years ago.
