Yes, if the receiver light is strong, the field is strong enough.
If receiver light is on and it’s bright that means that the receiver is converting the electrical signals to something.
Now these two points among tuning while light becomes on and be bright.
If you tune to the higher one (the frequency on the Transmitter) which is in the instructions that we give anyway.
It’s a first time when the light goes bright as you tune anticlockwise Then it is a guarantee that you got scalar field established.
