Logic Masters Deutschland e.V.

Rules:

Normal sudoku rules apply.

Radios: The red rectangles are walkie talkie radios. There are 10 in the grid but each radio is paired with only one other. The digit in a radio is the row number of its paired radio.

Antennas (Renban lines): Pink lines contain a non repeating set of consecutive digits in any order.

Frequency modulators (zipper lines): Any pairs of digits that are the same distance along the line from the blue oval in the centre must sum to the ovals digit.

Amplitude modulators (black kropki dots): A black dot sits between two digits where one is double the other.
