    The antenna system includes some type of curtain array? Is it correct?
    Thank you!

    Yeah it looks like a curtain, but Mike said that's all gone now.

    Nice TX, but here is no more room after the purchase of the 10 KW Collins and 60 KW Nautel Medium Wave cabinets..
    I have combined 4 Nautel PA's each 1.25 KW in a separate closet to get 5 KW carrier. Pictures will come soon here.
    During the first tests on 1.85 MHz. the HF PA efficiency was still acceptable..about 86%

    They still have a website, but it looks like all they might have left now is a podcast. I guess maybe they are off the air now for good, but I'm not sure.

    It was originally the Voice of Canada and that transmitter has been off the air since June 2012 so its been sitting there a long while.

    In February 1945, the "Voice of Canada" spoke to the world for the first time. The CBC International Service was founded to broadcast to Canadian Forces overseas in the Second World War. At war's end the radio service focused on telling the world about Canada in over a dozen languages. Despite budget cuts and critics who accused it of employing communists or operating as a government mouthpiece, the service now called Radio Canada International has persevered. CBC Archives looks back on RCI's six decades on shortwave.

    Radio Canada International (RCI) is the international broadcasting service of the Canadian Broadcasting Corporation (CBC). Prior to 1970, RCI was known as the CBC International Service. The broadcasting service was also previously referred to as the "Voice of Canada". In June 2012, shortwave services were terminated and RCI became accessible exclusively via the Internet. It also reduced to services in five languages (in contrast with the 14 languages it used in 1990). CBC also ended production of RCI news.[1]

    CKCX were the call letters used for the Canadian Broadcasting Corporation's shortwave transmitter complex near Sackville, New Brunswick at the Tantramar Marshes. The Sackville Relay Station was operated by Radio Canada International and broadcast its programming around the world as well as relay transmissions from several foreign shortwave broadcasters. Domestically, it transmitted broadcasts on 9.625 MHz to northern Quebec by CBC North, the James Bay Cree Communications Society and Taqramiut Nipingat, the Inuit communications society of the Nunavik region of northern Quebec.[1] The CKCX designation was assigned after CBC Radio's CBA, under whose licence the Sackville complex originally operated, moved to Moncton in 1968. Sackville was also used by Radio Japan, China Radio International, Voice of Vietnam, BBC World Service, Deutsche Welle and Radio Korea as part of a transmitter time exchange agreement.

    The Sackville facility was an impressive mixture of diverse technologies. The whole facility was controlled by computer automation which was centralized in the main control room. Frequencies, antennas, and input feeds are switched all according to internationally agreed upon schedules which were renegotiated twice per year with other countries.

    Sackville transmitter power level breakdown
    • There were 9 transmitters in operation in 2012.
    • (3 or 4) x 100 kW
    • (3 or 4) x 250 kW
    • 3 x 300 kW
    Radio Canada International's shortwave service was shut down in June 2012 due to Canadian Broadcasting Corporation budget cuts as a result of reduced federal subsidies. As a result the Canadian Broadcasting Corporation sought to sell the Sackville site to either another international broadcaster or a wind farm company. According to Martin Marcotte, director of CBC Transmission: "[The Sackville complex] will be fairly costly to dismantle and as a last resort we would dismantle the facility, return it to bare land as it was when we first acquired that site."[2] The transmission site was officially closed on October 31, 2012, at the conclusion of several contracts leasing transmitter time to international broadcasters.[3] The site, however, continued to be used until December 1, 2012, for transmission of CBC's Northern Quebec service until the installation of several low power transmitters in the target region could be completed. The CRTC granted a request by the CBC to revoke CKCX's license effective December 1, 2012.[4] The site was subsequently dismantled. After failing to receive any bids to purchase the complex, the antennas where dismantled and transmission towers demolished in 2014.[5]

    RCI's parent, the Canadian Broadcasting Corporation, was the owner and operator of the Sackville transmission site, call sign CKCX. RCI's only transmitter site was located on the Tantramar Marshes several kilometres east of the town of Sackville, New Brunswick. RCI leased or bartered its spare transmission capacity with other international broadcasters. Sackville was the only high power shortwave relay station in Canada and also transmitted CBC North broadcasts to northern Quebec.

    This transmitter and all meter panels are made to measure for this building.
    when this transmitter is being deafened, you will not be left with many useful bars.
    Maybe better to buy the whole building and move over to Canada.:biggrin:..

    That or the inside of the building was designed to fit the transmitter. My guess is they built that area around the transmitter.
    You know what the bad thing is about these old 1940's BC station transmitters being retired one by one like this? If there was ever a nuclear blast here and there because something bad happened in some shit-hole country the only thing that would still work are these old 1940's tube transmitters. I think many of these old stations even had generators on site to create their own power if necessary.

    These old mighty backups are being eliminated around the world. Wait until we wish they were still there. Not too smart.

    My Nautel transmitter comes from such a building, walls of more than 1 meter thick of reinforced concrete and an impact-resistant spherical roof, temperature and humidity controlled. Was built in the 40s. The advantage of this Nautel is that it is modular built in 19 "cabinets and plug able Solid State PA's of 1.25 KW.
    This old tube transmitter as described, looks good so i can see in the picture, but there will not be much good left after disassembly ... I think.

    It is sad to see that stations like these simply disappear from the face of the earth. The rise of the Internet is only to blame for these rapid changes !! In 20 years, people wonder ... How communication was in the 20th century .. One will have to be content with photos from Google and a lost YouTube video!
    Sad... Sad... Sad !!!

    Entrance transmitter building built in a mountain. Now it's an Broadcast TX museum.

    My Nautel 60 KW Medium Wave TX in this building before disassembly.
    Was an spare TX, runs 196 Hours only.. (by build in Hour counter)
    This TX was almost not used because of the radiation in the nearby village of LOPIK in the later years..
    Total costs (Tax Payer) was about 300.000 HFl.. about... 170.000 USD..

    This symmetrical 30 meters high TX building came after WW2, with all generators for all transmitters on the medium wave..
    Now .. it is for sale !! But belongs to conservation! May not be removed !!

    This TX Antenna was connected to the Nautel on 747 KHz. was about 100 meters away from the TX location, connected by 3 5/8 double coax feeders.

    During Christmas time, we have the biggest Christmas tree from the whole World.. almost 400 meters high.
    From our TV Broadcast antenna. (Still in use).. By driving on the A2 Highway, you can see it from 50 KM distance..
