Portugal is still broadcasting on mediumwave, albeit not on many frequencies. Their state broadcaster RDP can sometimes be heard on mediumwave 630, 666 and 720 kHz with their Antena 1 programming.
Paula Carvalho, Engenharia, Sistemas e Tecnologia confirmed my reception of Antena 1 with an e-mail and an old QSL card (shown above). My report was made last February on 720 kHz when the signal of Antena 1 at times was better than the signal of the usual dominant station BBC Radio 4. Antena 1 is listed with 4 different transmitters on 720 kHz, each with a power of 10 kilowatts, but I suspect most are running at lower power.
