If you want to build a link to the past via a digital modem of your
own design, you have to understand a few basics. First the Barkhausen
Criterion in Oscillator Design.

The Second Part of what you need is how to use Class B Push Pull
Amplifiers because you will need to take advantage of Crossover
Distortion.
http://www.electronics-tutorials.ws/amplifier/amp_6.html
To use Crossover Distortion as a Schmitt Trigger:
http://hyperphysics.phy-astr.gsu.edu/hbase/electronic/schmitt.html
Let's say you don't know whether the phase is going to be 0=B0 to 180=B0
and useless, 360=B0 and lost in circuitry, or 540=B0 and frequency
dependent, or 720=B0 and two cycles back for every one cycle forward.
If you make your own coil, you will find out that it has nothing to do
with resonance or the self resonance of the coil.
Let's say you build the oscillator, and when the crossover distortion
has both transistor conducting when the signal in is at 0 volts, it
should self start as a result of background radio noise. If the level
of crossover distortion is increased below the feedback signal's
output and higher than the background radio noise, it cannot self
start and will require a pulse to trigger the oscillation to start.
That is where you want your circuit biased. Then you need to build 2
more just like it.
OSC 1 =3D Clock Pulse High, [when on]
OSC 2 =3D Clock Pulse Low, [when on]
OSC 3 =3D One or Zero, [when oscillating or not]
On is considered only the presence of AC for the digital aspects of
the circuit to capture the present in the past. The moment you hit
send, the moment the circuit was completely turned on, you should have
your digital circuitry ready. From a human perspective, if you
trigger the oscillator to start, it has always been running. Turn on
from the supply without a trigger pulse and you can wait all day, then
turn off the circuit without sending a trigger pulse and it never
oscillates. So, you will need a large value of capacitor to lead into
this and a regulated power supply with limited ripple. You do not
want to trigger the oscillation without the triggering pulse being the
sole means and ways.
When you start the circuit the digital circuitry will respond by
turning OSC 1 on. Then it checks OSC 2 and OSC 3 for data, [1 or 0].
At any point in time that a signal is found on OSC 2, OSC 1 is shut
off. In the past after the data is received, the bit counter is
advanced from 0 to 1, each time a signal is detected on OSC 2. If OSC
3 is on, then the bit equals 1, if OSC 2 is on and OSC 3 is off the
bit equals 0. Once the data counter has advanced 1 bit in the past,
it resets OSC 2 and OSC 3, then turns on OSC 1, and continues until
the end of the message, or messages.
Astronauts come back a few seconds younger. So, what's 200uS back in
time?

Actually, they don't come back younger. They just come back less older than
everyone else.

A couple of shafts and a few gears will make lots of phase shift, too.
Years, if you like.
