Enaire (informacion@enaire.es) was so kind to confirm another couple of beacons from Spain that I received. This time I heard NDB VT from Vitoria on 308 kHz. As usual they sent their nice information sheet:

NDB 308-VT is one of the two NDBs for Vitoria Airport. The other beacon is is 345-VTA. Below you can see how they nicely align with both sides of the runway. Both antennas have a set-up which is a bit different from most Enair beacons: a “Sistema radiante de tipo margarita” as opposed to most Enaire beacons that have a dipole: “Sistema radiante de tipo T”.
