A Marathon was being transmitted by 2 motorcycles with wireless camerasystems. The transmitters are "link research" and the class-A amplifiers are custom made bij Videolink.

Videolink uses 2 receive sites (2,5 Km distance from each other) which are connected via 2 ASI microwave links. 2 "Link Research" ASI switch/decoders deliver the two SDI signals to the customer.

The shading and tally signal for both the cameras is multiplexed and modulated on UHF and transmitted from a 40 Meter height.
