My coleagues of RNE in Sevilla (Andalucía) recently asked for my permission to use the design of the eQSL we use at RNE-Salamanca to produce their own.
They told me that they hold a big number of QSL requests unanswered (some very old) that now will be replied!. They are also planning to establish a email address to this purpose but for now reception reports can be sent to:

Atención: Departamento técnico RNE
Radio Televisión Española
Isla de la Cartuja. Parque del Alamillo
(Edificio RTVE)
