".........From Radio Tirana International:
80 years of Radio Tirana
November 2018
Radio Tirana has an 80 year history, dating back to 28 November
1938. It was the first Albanian radio station launched by King
Zog I and Queen Geraldine in a ceremony at Tirana City Hall of
that time. A year earlier, a shortwave transmitter with a power
of 3 kW at 40 meters was put in operation in a building at Kont
Urani Street (Tirana) and intended mainly for communication, but
was also used to broadcast 3 hours of programs per day. The first
broadcast consisted of choral singing, where Jorgji Truja and
Marije Kraja sang an introductory piece, followed by the unique
timbre of Kaliopi Nushi's voice who pronounced the following
phrase: "Ju flet Tirana" (English: This is Tirana speaking). This
moment officially marked the first broadcast of Radio Tirana...."

".....How spectrograms are created?
by Merkouris SV2HWM
Many listeners wonder how the waterfall graphics, aka sonograms
or spectrograms, such as the Shortwave Radiogram logo and last
week's Arecibo message, have been produced. Here follows the
detailed story behind the creation of these spectrograms and how
I've got involved.............
........In 2016 the frequency of 6070 kHz, apart from Channel 292, was
also used by Vatican Radio for their daily Rosary broadcasts.
Then, Rainer Ebeling at Channel 292 took the decision to
broadcast the DigiDX program during the time slots used by
Vatican, offering free extra broadcasts twice a day. It was a
wise move because only the digital content could survive the
signal from Santa Maria di Galeria that was booming all over
Europe. These extra broadcasts, mixed with Vatican's powerful
signal, offered a great opportunity to test and compare various
digital modes........"
