Luqa Aero (9HA) :
the typical sound of a radioteletype test (rb, 1985)
just in case you have no decoder at hand ;-)
Rudy van Dalen received the radioteletype transmission in 1981
here a verification letter for a reception of the air/ground control services (rb, 1985)
in 2020, I made a visit to the transmission center in Benghaisa (rb)
here is the page of the actual operations agency 'Malta air traffic services'
