in this recording you'll hear *BJO-316
(Bear Island, Bjornoya) and *HG-317
(Trondheim) simultaneously (Lars Lundström, 2014)
this prepared QSL letter
shows the reception path of the signal...
... which came from this lonely antenna in the wilderness of
Bjornoya (both from the collection of Michael Oexner)
