Is this for real? Broadcast interrupted in UK

Back in 1977, several broadcasts in the UK were interrupted by what some believe were messages from extraterrestials.  Now we cannot accept blindly that these messages were not fakes, and we are asking anyone who accessed this site this question.  Do you know, or are you aware, if there was any type of technology in 1977 that might allow someone to override a TV broadcast for the purposes of perpetuating a hoax?

The message that was broadcasted on at least three stations without the knowledge, permission or even awareness that it was happening by the stations themselves is as follows:  “This is the voice of Gramaha, the representative of the Asta Galactic Command, speaking to you.  For many years now you have seen us as lights in the skies.  We speak to you now in peace and wisdom as we have done to your brothers and sisters all over this, you planet earth.  We have come to warn you of the destiny of your race and your worlds so that you may communicate to  your fellow beings the course you must take to avoid the disasters which threaten your worlds and the beings on our worlds around you.  This is in order that you may share in the awakening, as the planet passes into the new Age of Aquarius.  The New Age can be a time of great peace and evolution for your race, but only if your rulers are made aware of the evil forces that overshadow their judgments.

“Be still and listen.  Your chance may never come again.  All your weapons of evil must be removed.  The time of conflict is now past, and the race of which you are part may proceed to the highest plane of evolution if you show yourselves worthy to do this.  You have but a short time to learn to live together in peace and good will.  Small groups all over the planet are learning this and exist to pass on the light of the dawning new age to you all.  You are free to accept or reject their teachings, but only those who learn to live in peace will pass to the higher realms of spiritual evolution.

“Hear now the voice of Gramaha, the representative of the Asta Galactic Command, speaking to you.

“Be aware also that there are many false profits and guides operating on your world.  They will suck your energy from you…the energy you call money, and will put it to evil ends giving you worthless dross in return. Your inner divine self will protect you from this.  You must learn to be sensitive to the voice within that can tell you what is truth and what is confusion, chaos and untruth.  Learn to listen to the voice of truth which is within you and you will lead yourselves onto the path of evolution.  This is our message to you, our dear friends.  Watched you growing for many years as you watched our lights in your skies.  You know that we are here and that there are more beings on and around your earth than your scientists admit.  We are deeply concerned about you and your path towards the light and we will do all we can to help you.  Have no fears; seek only to know yourselves and live in harmony with the ways of  your planet earth.  We are Asta Galactic Command.  Thank you for  your attention.  We are now leaving the planes of  your existence.  May you be blessed by the supreme love and truth of the Cosmos.”
