A complete scan at the highest point in the house gives me several more instances of Digitenne signals. As mentioned before, at 618 MHz Digitenne bouquet 1 with TV Noord-Holland, but also at 786 MHz and 826 MHz bouquet 2. These can come from a number of locations, I can only find out with a directional antenna. Due to the way several stations broadcast exactly the same program at the same frequency there is no way of knowing which station is transmitting it. The fact that the signals have to be exactly the same to avoid interference means there can be no identifying bits somewhere within the dvb datastream. I think it is way cool that transmitter technology is this far that we can transmit the same signal from different locations without interfering with eachother. It is probably the robustness against multipath interference that makes this possible: having more transmitters with the same signal is a form of multipath interference.
