After 1974, Albania entered the deepest phase of its historical isolation. After the deterioration of relations with China, the communist regime of Enver Hoxha began closing every window of communication with the outside world.
Not only were the land borders sealed, but the airspace became impassable. The systematic jamming of television signals from Italy, Yugoslavia, and Greece began.
VNA has obtained an official document from 1974, where the Director of Posts and Communications, Perikli Pani, sends Hysni Kapo the plan for placing dozens of jamming devices in border areas, to block any foreign television waves.
"With the commissioning of the Dajti television transmitting center, it was possible to cover about 20% of the surface of our country, mainly the plain and coastal areas, where about 45% of the population resides. To expand the coverage of the country with television signals, in the border areas and densely populated areas, in recent years several locally mounted television repeaters have been and will be installed; by the end of 1974 the surface area covered is expected to reach 30%, while the population is about 68%. So far, 18 television repeaters have been installed in the following places: Kukës, Fierz, Puke, Peshkopi, Elbasan, Bulqizë, Librazhdë, Pogradec, Korçë, Ersekë, Çorovodë, Përmet, Gjirokastër, Delvinë, Saranda, Berat, Orikum and Poliçan (Berat)" - the document states, among other things.
This measure, along with the expansion of the network of domestic broadcasters, aimed to strengthen the single ideological monopoly: the Voice of the Party. In this way, Albania's isolation was no longer just political or diplomatic, it extended to the minds, ears, and eyes of its citizens.

Albania became a country where even the airwaves were banned, where every word coming from abroad was considered a threat, and where ideological solitude became the state norm. This was the beginning of the total closure of the country that would last until the end of the regime in 1991./ VNA
