Slovenian littoral and might therefore have been deemed unwanted competition. Other big commercial Italian channels were also targets of the so-called Frequency war, for example most frequencies of Canale 5, Italia Uno's sister channel, were covered too, as were those of the second sister channel, Rete 4. La7 (formerly Telemontecarlo) and MTV Italia (formerly Videomusic) were also subject to interferences, however so were also the Slovenian POP TV and Kanal A, subject to interferences from the Italian side (though the Italians were the first to broadcast on those frequencies). There was also a mysterious fire at the Conconello transmitter around the same time, which damaged the transmission equipment of Telefriuli, causing it to reduce the strength of its signal, limiting its availability on Slovenian territory. The causes for that fire have to this day not been established, and the possibility it was a Slovenian terrorist attack against the transmitter exists. Temporary stop In around 2005, the situation came to a temporary stop, as the signal of Sponka.TV on UHF 52 disappeared, leaving Italia Uno visible with a clear picture again. The complaints subsided and the situation returned to normal. Sponka.TV resumed its broadcasts on Cable TV. The reasons for that are to this day unknown, and most people at the time thought the channel simply gave up and desisted. However, that would soon prove false. Resumption The crisis resumed when Sponka.TV's signal returned and Italia Uno disappeared again. Complaints from the local population flared up again but were again ignored. Eventually, the signal's strength was increased again. Soon, the channel also turned on a second frequency, UHF 30 from Ankaran-Hrvatini, making it impossible to receive La7 (formerly Telemontecarlo) in some places. And, just like UHF 52, the signal on UHF 30 also interfered on Italian territory. In addition, the channel's broadcasts were also detected on UHF 34 in Divača, possibly from Sežana, without any license, whatsoever, and it eventually also obtained frequencies on a transmitter north of Nova Gorica, again without license. Apparent end Since December 2010, the controversy has become moot as Italy and Slovenia have both switched off the analog signals, and the digital multiplex inside which Italia Uno is located is on channel UHF 49 (between 2010 and 2012 on UHF 36), and was never on Sponka.TV's UHF 34. However, for a while, UHF 52 and UHF 30 both kept transmitting in analog even after the switch
