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.
Solution code: The digits in the radios read in western reading order (left to right each row going down the grid)
