Morse code at Eurovision?

There is an early indication that morse code will be the chosen method of communication between the Heliport and the Kyiv International Exhibition Center during the 2017 Eurovision Song Contest in Ukraine 

A ESCKAZ website report on the success of Kyiv in beating rival cities of Dnipro and Odessa to host the contest says: 

There is an idea to make a connection between locations using a type of Morse code. Guests of the Eurovision will be able to communicate from the roof of the heliport with flashing lights, waving flags with those who will be in IEC and in this way supporting their countries
