NDB GRN on 412 kHz is a beacon situated north of Girona Airport, in line with the runway. It is often listed as Gerona, which is the Spanish name for the city of Girona in Catalunya, but I prefer to use the name that the local population uses. My reception report was verified by Enaire via informacion@enaire.es .
The set-up of the beacon is typical for most of the Spanish NDBs: a 200 W transmitter with a “Sistema radiante de tipo T”:
Girona Airport was built in 1965 when there was not a lot of traffic. Passenger numbers grew spectacularly after Ryanair chose Girona as one of its European hubs, marketing it as ‘Barcelona-Girona’. In 1993, Girona Airport dealt with only 275,000 passengers; in 2008 passenger numbers increased to more than 5.5 million. But when Ryanair moved their Barcelona operations from Girona to the larger El Prat International Airport much of this was lost again. In 2024 around 2 million passengers used Girona Airport.
Nice catch, Peter! Only about 50 km from my home!
