I’ve just seen this spot on SW3 and I fear there must be an error:
My understanding is that all foreign hams under the CEPT agreement, must use the CT7 preffix before their home callsign when operating from mainland Portugal, i.e. the territory in the Iberian peninsula. The preffix must be different if the operation takes place in some of the Azores Is. and different again if from Madeira Is., but I don’t remember which ones.
In case someone can get in contact with @M0JJO, it would be interesting for him to be informed about this, otherwise, his activation may be considered invalid, I’m afraid.
In case this CT7 preffix rule had changed and I’m not aware, thanks for letting us all know.
