F Ny Dakar :

 

old recording, and the transmitter apparently even older: VVV FAAE de 6WW (rb, 1974)
this VVV marker was recorded in 1987 by Andy Stumpf
in 1984, they used RTTY for channel marker (rb) just in case you have no decoder at hand ;-)

 

a letter from 1981 (Peter Conway)
detailed QSL letter (Frank Schüttig, 1990)
nice letter with handpainted symbols (Ary Boender, 1990)
and for verification here a colorful post card (Vladimir Rozhkov, 2001)
