The Radio Canada International shortwave transmitting station at Sackville, New Brunswick, is situated near the Trans-Canada Highway on the Tantramar salt marshes near the Bay of Fundy. It can be seen from the Halifax (Nova Scotia) to Montreal passenger train (the ‘Ocean’). The salt marsh location is believed to improve performance.

The station has a complex assortment of antennas, driven by ABB 250 kW transmitter units made in Switzerland. Normally, several are in operation at the same time.

Their outputs go via 300 ohm balanced lines to the antennas. The parallel curtain arrays require a constant spacing in order to keep a good standing wave ratio on the feeders from the transmitters.

Most aspects of the station are automated, with a small local staff to deal with problems (which include maintaining transmissions in an optimal way during adverse weather conditions).

In addition to transmissions for Radio Canada in various languages (including Russian, Ukrainian and Chinese) directed to various countries, programs of NHK, Radio Korea and other broadcasting organisations are also transmitted under contract. The central colour screen at the control desk shows the current schedule, and the matrix display above shows the connections of the transmitter units to the antennas. Program material is received by digital and analogue land lines and also via some satellite links. The station used to offer daily tours to the general public, but these have now ceased. However, I was able to get a nice personalised tour by going to the front door and ringing the bell.

The main parts of a previously used RCA 50kW transmitter unit are kept on display.
