I was really surprised to pick up a NDB signal from the Azores with considerable signal strength. Below you can see the Pskov recording (I added the morse code for clarity):

The email to QSL NDB FIL-380 near Horta on Faial Island indicates a power of 700W which, in combination with propagation over water, might explain why the signal came through so well.
I sent my report to geral@nav.pt which is the general email address for NAV Portugal, responsible for flight safety in Portugal and the Portugese Islands.


Horta airport is situated on Faial Island. The airport was established in 1971 and offers flights to nearby islands but also to Lisbon, Portugal. On the photo below you see the runway close to the sea and in the distance you see the volcano on nearby Pico island:
