W2UP> It's the receiving station that has the hard job! Yes, it is because of all the QRO signals nearby. QRP signal must be above the composite noise. Just preparing second VXO TX and 3L20 for another try on 1988 EU record. I need 600 DX so please listen to my 48 hours CQ at 14.060 kHz. 73 de Mario, S56A, N1YU
