I was wondering if it would be a good idea to transmit digital signal through the tether using FSK modulation. This would allow fewer distortions and reflections in the wire. And in consequence this should allow further distances
There are some cool modules that can already make the modulated signal. Then to demodulate the signal I should only make a low pass or high pass filter before putting the input in an microcontroller.
What do you guys think?

here are some pictures showing FSK modualtion:
