On my second attempt I received a fully detailed email, with their nice logo, to QSL MRCC Lisboa 2187.5 kHz. I received them acknowledging a DSC test of RoRo ship “Grande Brasile” on its way from Portugal to Senegal. I sent my report to mrcc.lisboa@marinha.pt . Please note that I edited the picture of the QSL email to remove phone numbers etc. for privacy reasons.
