Radio Museum

I would like to inform you about an activity which is maybe interesting for you/your webpage in this context. As a passionate radio enthusiast and member of radiomuseum.org I have initiated the project COHIRADIA which aims at conserving whole AM broadcasting bands (raw broadband signals) containing all stations active at a certain time. My archive is still small but growing and dates back to 2006 when, among others, German, Dutch, Swiss and French MW and LW transmitters were still active.

On Sept. 10th I recorded many hours of the MW band with an RSP1A SDR (overall more than 120 GB) and (so far) archived the part with the last hour of RAI MW on two files:

RAI_MW_theEND_lasthour.wav  (64 min 18GB)

RAI_MW_theEND_incl_anthem.wav (approx 13 min, short version, 4GB)

These files can be played back by any interested person on a PC with software like SDRUno or SDR#. Several Italian stations, especially on 900 and 657 kHz, can be listened to until the very end with the Italian Anthem conducted by Fabio Luisi and the 24:00 time signal. So they may complement the Audio file which was added on 11-09 ( Kai Ludwig to WOR iog). People who possess a STEMLAB125-14 by Redpitaya can even play back and tune through on old analogue radios.

In the next weeks I will also add recordings from 10th of August when I took a Ferry to Greece from Venice and recorded the MW band with most Italian transmitters both during daytime and nighttime.

I would be happy if you find my contribution interesting enough for a short comment in your very informative webpage.

Best regards

Kalundborg 243 kHz.
It has been observed that the transmitter seems to be on reduced power.

Btw – tomorrow is the station’s 95th birthday. Hip hip hooray!

Argentina

Radio Nacional Argentina will make a historic broadcast. There will be 52 uninterrupted hours on the air, with the participation of the 50 stations from all over the territory and as a tribute to the 102 years of Radio in our country.

The transmission will begin next Friday , August 26 at 8:00 p.m. and will end on Sunday, August 28 at 11:59 p.m.

In preparation for this historic event, a draw was held to determine the time slot that each of the stations that make up the State broadcasting system would have to produce and broadcast. It was chaired by the executive director Alejandro Pont Lezica and the station managerJuan Martin Ramos Padilla.

It will be a historic transmission, with the federal imprint that this management has given to the operation of Radio Nacional. Stations from all over the territory will participate, including LRA36 Radio Nacional Arcángel San Gabriel from Base Esperanza in Argentine Antarctica.

It will have the participation of more than 500 workers from all the stations, covering the technical operation in studios and transmission plants, journalistic production, locution, airing and coordination.

Throughout the 52 hours of transmissionwe will be able to enjoy the varied texture of the voices that give life to the air of Radio Nacional throughout our territory. There will be the record of the voices that made the Radio, the music that filled the silences and the recorded testimonies of the events that marked these 102 years of history in our country.

The music, the voices and the history of our country synthesized in the air of the 50 stations of Radio Nacional, throughout 52 hours , in homage to the 102 years of Radiophony.

Kyrgyzstan

The TWR Asia Center in Kyrgyzstan.
For the Trans World Radio, medium waves are the best investment and they remain viable to reach target audiences in the remote parts of the world. In addition, medium waves have the ability to travel great
distances at night and also to cover rough terrain.

That’s why the Red River Tx site near Bishkek, Kyrgyzstan, became a home to two sections of TWR:
1. PANI on 1467 kHz and
2. CAMENA on 1287 kHz.
PANI stands for Pakistan, Afghanistan and North India and
CAMENA for Central Asia, Middle East and North Africa.

In addition to TWR broadcasts, Kyrgyz Radio broadcast on 612 kHz from this transmitter center. The TWR CAMENA started broadcasting their programs in March of 2003 with a power of 150 kW. The station was closed at the end of 2016, because the transmitter, which dated from the time of the USSR, was out of order.

CAMENA’s Central Asian Broadcasts had been reduced and moved to the PANI transmitter on 1467 kHz. For the frequency 1467 kHz a directional antenna from 4 masts went into operation in 2014 with an output of 500 kW.

Then in 2019 the TWR had bought 2 transmitters from Germany at a very good price and reinstalled them on the Red River site. The diplexer made it possible to couple two transmitters to reach 200 kW. With a new directional antenna it became possible to cover some 60 million people dispersed in the vast steppes of Kazakhstan, Uzbekistan, in the valley of Kyrgyzstan and Tajikistan and in Afghanistan, North West of China, North of India and Africa – to 10 countries.

In the last period of time – in 2020-2021 – the TWR was on the air on 612 kHz, 200 kW for the TWR Europe and CAMENA and also on 1467 kHz, 500 kW for the TWR PANI.
In 2022 the TWR CAMENA is just on 1467 kHz in different languages.

Cuba

Havana, Aug 22 (Prensa Latina)
President Miguel Diaz-Canel on Monday congratulated producers and listeners on the occasion of the centenary of Cuban radio.
https://www.plenglish.com/news/2022/08/22/diaz-canel-congratulates-cubas-radio-on-its-100th-anniversary/
On his Twitter, the president wished “that for the next 100 years it will continue sounding with the Cuban spirit that distinguishes it.
With the beginning of radio transmissions on August 22, 1922, Cuba was among the first countries in Latin America to have this kind of communication.
The accelerated development of the medium allowed that less than a year later 24 transmitting stations were registered, including 14 in Havana.
By the end of 1923, that number rose to 31 radio stations throughout the country.

The creation of Radio Rebelde in the mountains of the Sierra Maestra, on February 24, 1958, marked the beginning of the National Radio System, which has focused on the dissemination of knowledge, culture, recreation and the ideological, social, ethical and aesthetic values of the Cuban people.

Cuban radio began its first digital transmission in 1998. Today, the 97 digital radio stations produce their own contents.

Canada

We Return to the Early Radio Scene in the Canadian Province of Manitoba.

During the year 1922, there were two mediumwave radio broadcasting stations on the air in Winnipeg, Manitoba, and both were vying for the attention of the most listeners over the widest possible areas of
Manitoba and neighboring Canadian and American territories. These stations were CJCG operated by the Free Press, and CJNC operated by the Tribune, and both were losing money.

Thus both stations were quietly closed, after just less than a year of on air operation, with the final broadcast from the Tribune CJNC on Friday afternoon March 9, 1923, and the final broadcast from Free
Press CJCG next day, Saturday March 10, (1923) at noon. However, their death gave rise to the birth of of one of Canada’s most notable callsigns, and also to the highest FM power ever permitted in North
America.

Replacing the CJNC and CJCG callsigns was a new mediumwave station with the unusual though now well known historical callsign, the three letter CKY, the first usage of this new call. The station was installed in the Government Telephone Building on Sherbrooke Street, a little south of Portage Avenue, with a flat top antenna on the roof.
Their 500 watt transmitter was manufactured by Northern Electric and their inaugural broadcast was a local staff presentation at 8:30 pm on Tuesday March 13, 1923, just a few days after the close of the two
earlier stations.

Interestingly during the following year 1924, came the appearance of Canada’s first phantom radio broadcasting station, an additional callsign superimposed upon an already existing station. The new
additional call was CNRW operated by the Canadian National Railways System and it was noted over the new CKY in Winnipeg. The income from the phantom broadcasts over the new CNRW-CKY enabled the Winnipeg station to survive financially.

In 1948, the original CKY was purchased by CRBC-CBC Radio in Canada, and it was rebranded as CBW. Earlier this year, the original CKY-CBW, with 50 kW on 990 kHz was honored with a special historic display in the City Library, and with a series of programs and interviews over the modern and nowadays widely heard CBW.

The second usage of the famous historic callsign CKY was implemented on December 31, 1949, when Lloyd Moffatt reintroduced the callsign in Winnipeg for an AM station with 5 kW on 580 kHz.

Then in 1963, an FM outlet was appended to the CKY mediumwave station and this new transmitter was on the air with a fantastic one third of a million watts, 360,000 watts, on 92.1 FM. That overload of FM power is by far the highest power ever permitted on the FM band in North America, though FM transmitters with 200 to 400 kW are still quite common in western Europe.

During the year 2004, CKY-FM moved to 102.3 FM, and the power level was reduced to 70,000 watts, still quite high. Two years ago, the callsign CKY was dropped and the station became KISS-FM. Their studios
are in Osbourne Village South in Winnipeg, and their transmitter is at Duff Roblin Provincial Park.

{Surely it is officially still CKY-FM, and with 100/100 kW ERP per WTFDA FM Database — gh}

And that then is the story of one hundred years of historic radio broadcasting in Winnipeg Manitoba, an event that was honored appropriately throughout their city earlier this year.
