This mod adds 1 item, the link relay. It is a compact utility block for Create’s Redstone Link system that lets you remap wireless frequencies.
Set an input frequency pair and an output frequency pair, and any signal received on the input will be transmitted on the output. You can stack unlimited bindings in a single relay block.
This item stemmed out of frustration for not being able to fit the controls on my small aeronautics engine, and having ground relays meant that the controls would break down when I flew further than 256 blocks.
^The old system^
Simplified down to a single block
The relay also allows you to invert to the signal, so the output frequency is always active unless it is recieving the input.
