Default Receiving 2 GHz AM signals in space. What do they sound like?

Hi:

Let's say I am in a space station which has a 2 GHz DX AM analog
receiver that receives the magnetic fields [while ignoring the electric
fields] of extremely weak 2 GHz AM analog carrier signals. In addition,
this receiver is so sensitive and powerful that it can clearly pick up
AM carrier waves as weak as 10-to-the-power-NEGATIVE-10,000
watt-per-meter-squared. 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. This receiver has an astronomically-powerful amplifier which
amplifies those extremely-soft carrier waves until the resulting
modulation signals will be just loud enough for the human ear to
coherently detect. Following this amplification, the carrier waves are
demodulated to modulation waves -- the stuff we "hear" -- and then sent
to loudspeaker so those onboard can hear those sounds.

Equally important, the 2-GHz receiver is pointed away from the earth to
assist in preventing the pickup of signals generated from Earth.

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


The sound of absolute zero, which sounds a lot like the sound
of absolute infinity, except that morons at Viacom pick
up the tab, rather than morons at AT&T.







Thanks,

Radium
