at 110 light-years away from earth — the edge of a radio ‘sphere’ which contains many star systems — our very first radio broadcasts are beginning to arrive. At 74 light-years away, television signals are being introduced. Star systems at a distance of 50 light-years are now entering the ‘Twilight Zone’.
[One] way to think of [the inverse square law] is that the strength of a radio signal will be only 1/4 as great once you are twice the distance from the source. At ten times the distance, the strength of the signal would only be one hundredth as great. Because of this ‘inverse square law’, all of our radio signals become indistinguishable from background noise at around a few light-years from earth. For a civilization only a couple hundred light-years away, trying to listen to our broadcasts would be like trying to detect the small ripple from a pebble dropped in the pacific ocean off the coast of California – from Japan
Human beings are making it harder for extraterrestials to pick up our broadcasts and make contact, the world's leading expert on the search for alien life warned yesterday. "The trouble is that we are making ourselves more and more difficult to be heard," said Dr Drake.
"We are broadcasting in much more efficient ways today and are making our signals fainter and fainter." In the past, TV and radio programmes were broadcast from huge ground stations that transmitted signals at thousands of watts. These could be picked up relatively easily across the depths of space, astronomers calculated. Now, most TV and radio programmes are transmitted from satellites that typically use only 75 watts and have aerials pointing toward Earth, rather than into space. "For good measure, in America we have switched from analogue to digital broadcasting and you are going to do the same in Britain very soon," Drake added. "When you do that, your transmissions will become four times fainter because digital uses less power."
"Very soon we will become undetectable," he said. In short, in space no one will hear us at all.

i can remember reading somewhere that it will take something like 300 years for the first radio signals to reach our nearest star. or i could be very wrong there, but its something of a significant amount of time for sure.
Now, the millitary/security forces are not stupid,

anyway, how do you think they can stop radio waves and signals going out into space?
they obviously cant.edit on 28/10/12 by SecretKnowledge because: (no reason given)

You say:
"So, Why would highly intelligent sucurity forces allow our continued and ever increasing announcment of our presence? Surely this is proof that they DO know who IS out there?"
You miss the obvious by having your question backwards.
They (the ETs) already know we are here. Being virtually masters of the universe, it matters not one fig what we broadcast out there or what weapon systems (such as "Star Wars" we pretend to have for our defence.

As far as Radio Wave Broadcasts...I wouldn't worry about it as this Planet has been being visited for Thousands of Years. It was not until we started Detonating Nuclear Bombs that Visitation and interest in our Nuclear Capabilities that OVERT Visitation became all too real.
To find proof of this look at the Massive E.T. Craft Flyovers of Washington DC in the early 1950's and 60's. The best place to look at this information as well as multiple interviews of both Civilian and Military Leaders public responses can be found in the Washington DC Newspapers which covered these two events that were witnessed by Thousands.
The early 1950's interviews are of particular interest as the U.S. Military was concentrating it's PR efforts to make the U.S. Population know that these craft were not Soviet...as they preferred to state that they were E.T. rather than allow the U.S. Population to believe the Soviets were more advanced than the U.S. Split Infinity

That's a big leap! The government in general is stupid and inefficient. They can't even run a competent post office -- what makes you think they run a competent military?
We don't put our military in the hands of the government because of the government's competency. We put the military in the hands of the government because the government is supposed to have a monopoly on violent force. A private company with the force of violence won't act very ethically..

Extent of Human Radio Broadcasts / The Tiny Humanity Bubble by Adam Grossman
Mankind has been broadcasting radio waves into deep space for about a hundred years now — since the days of Marconi.
That, of course, means there is an ever-expanding bubble announcing Humanity’s presence to anyone listening in the Milky Way. This bubble is astronomically large (literally), and currently spans approximately 200 light years across. But how big is this, really, compared to the size of the Galaxy in which we live (which is, itself, just one of countless billions of galaxies in the observable universe)?
To answer that question, Adam put together the following diagram of our galaxy with the “Humanity Bubble”
