[Suggestion] Signal transmission between grids

I thought of this as a way of acting on another ship remotely.

For this, i will consider an "emitter" and a "receiver" which can either be two distincts blocks or a single one : the antennae.

How this works is simple :

The emitter sends a signal through a certain frequency (from 0001 to 9999Hz). this can be triggered via player action, button, sensor etc...

A receiver programmed with the corresponding frequency will do an action : start a timer block, turn off a door, whatever.

So let's say i have a ship 1 with an emitter and a ship 2 with a receiver. both are programmed with 4765Hz.

When i emit the signal from ship 1, the receiver, set to 4765Hz, will trigger its action 1. when ship 1 stops emitting, the receiver on ship 2 will trigger its action 2. just like sensors.

What this can do :

I have a fleet with receiver set to a certain frequency which will trigger a red alert (turning turrets on, turning red lights on etc...)

When my station is attacked, i press a button which will order the emitter to transmit a signal to said frequency, then all the ship within range (range determined by antennas) will be set to red alert and know something's up.

Other use case :

I have roaming turrets around my base, i want a button to call them all. i press said button, emit whatever frequency they're set to. when they receive the signal, the receiver triggers the AI task recorder block to go back to base.

This will give much more use to antenna range, as well as laser antennas for triggering action on far installations
