QSL for NDB LOS Losinj on 429 kHz. The beacon is associated with Losinj Airport in Croatia, a small airport, mainly in use for smaller private airplanes and taxi services. It is situated on Losinj Island, and definitely one of the easier to receive beacons here in the Netherlands.

LOS Losinj is a pretty easy to catch NDB. Pskov recording.

As with the other beacons from the Istria region my reception was confirmed by Mr. Birkić, head of Istria/Kvarner ATC at Croatia Control.
