Could you explain why? Yes, you need a higher BW for Loran-C,
but the phase(f) function will give you only a distortion of
the signal and a constant time delay in your signal recovery.
But that shouldnt degrade the usefullness of the system.
What am i missing here?
Why does it take years to find the answers to
the questions one should have asked long ago?
