Wasn't it bug who wrote:
If we could in theory actually contact et's, wouldn't it make sense that their
planet is orbiting a star and emitting "pink-noise" radio signals, much like
earth does as it orbits the sun?

The problem with looking for broad spectrum radio noise (be it pink,
white or brown) is that there are natural radio noise sources, like
stars, that are much stronger than the random radio signals given off by
a civilization with a technology equivalent to our own. If the little
green men want to be heard, then we expect them to transmit a non-noisy
signal which can be picked out from the noisy background.

And if these signals act like light wouldn't
they theororetically be pulled into the "groove" that the earth's orbit dig's
into space as it spins around the sun?

You've completely lost me on this one. What makes you think light gets
pulled into a "groove"? Have you ever seen light wakes that are left by
other planets, or by the Moon? I haven't and I'd expect radio wakes to
be similarly difficult to detect even from short distances.

I'm also curious to what you send out as signals. I think it'd be a good idea
to recreate the scenario from "Close Encounters."
Like right a piece of music to sent out, but begin with a signal of 3bps, have
the signal pulse and pause for an equal time and allow the signals pitch to
increase and duration increase at a steady rate until the pitch reaches 180bpm
(i think) and have the instruments tuned to a-441 since its a number divisible
by three.

My understanding is that the achievable data rate over the sort of
signal that we are capable of transmitting over interstellar distances
is a fraction of a bit per second, so analogue audio signals are not
suitable. Anyway, we don't actually know that the ETs have ears. Binary
data signals are more sensible, possibly using Frequency Switched
Keying, or by simply switching the carrier signal on and off to send one
and zero bits.

Probably the most significant thing that you can say in such a
transmission is an indication that we are here and we don't mind anyone
knowing, and that message can be achieved by simply sending an
unmodulated narrow band carrier wave.
