From Radio TPOT:
“I broadcast on the 747 and 918 KHz. Both in C-QUAM. The 747 is extra, only for today and other special occasions.
The 747 kHz transmitter is from (Radio) Cupra, and we do the medium wave together, we have been friends for more than 40 years and both radio amateurs.
Our digital ether link was broken and we made a complet new one last winter That’s why you don’t have a time difference, because everything is real time. That was the technical challenge digitally and no delay like with an internet connection.”
