After a recent visit (12th October, 2026) to RTP Transmission facilities in Miranda do Douro, I checked the 630 kHz transmitter there and is OFF, so the only remaining Antena 1 txer on 630 kHz seems to be the one in Montemor-o-Velho. First week in September I could not hear neither the usual echoes from both transmitters, so could be already switched off at that time.
