Correct Call Sign Writing
I believe I have an easy question. I would like to install a W5OLF transmitter at my holiday QTH in La Palma/Canaris Island. My call sign in Spain is EA8/DL2YAY. How could I solve the problem with the "/" sign. As I understood WSPR uses only letters and numbers.
Thanks for your answers in advance
