... This receiver also has a robust signal processor
that can eliminate clipped-waveforms [such as square waves], spikes,
clicks, pops, hiss, and random noise
even at those trivial wattage
levels. After eliminating those unwanted signals, the carrier wave
is
amplified.


There is no carrier,


Yes there is. Why do you say there isn't? Certain waveforms in the
carrier wave that would cause the modulator signal to contain
clipped-waveforms [such as square waves], spikes, clicks, pops, hiss,
and random noise are removed. However, the remainder of the carrier-wave
remains unscathed.

it was one of those signals you just
eliminated.


How so?

If I am on this spaceship, what will
I most likely hear on the radio?


Stop trying to troll, you are too stupid to pull it off.


I don't troll or spam. I am asking this question because -- unlikely [if
not impossible] as my 2-GHz-in-outer-space scenario is -- I am still
interested in it.

Now please please please answer my question. What would I hear?

I chose 2 GHz because it is in the UHF band. UHFs tend to be best for
extremely long distance reception. Of the radio waves emitted by objects
trillions of miles -- or more -- away, UHF is usually the most receivable.


Why do you say that "UHFs tend to the best for extremely long distance
reception"? Have a look at the basic equation governing line-of-sight
reception.

Why do you not answer your own question? It sounds to me like as
reasonable a premise for a science fiction book as many that have been
successful. You could perhaps spin it into quite an interesting
story. You've already started with a premise that's so far from -- so
very, very far from -- the current realities or even the dreams of
people designing receivers that you may as well suppose you're going
to receive whatever your wildest imagination might come up with.
Since there is a nearly countless number of stars in the known
universe, and since a large percentage of them could be planetary
systems, each with the possibility of emitting interesting amplitude
modulated carriers, your choices are pretty near limitless. Wow! Let
your imagination run wild. It obviously did when you posed the
question; you may as well let it run as wild with the answer. Back to
you, Nonex!

Oh, and by the way, "spamming" comes, in one form, from posting too
many places; I've trimmed off a whole bunch of groups for this reply.
By my way of thinking, you're being pretty generous with yourself
saying you don't spam.
