Since 2001, at the request of RAC, Industry Canada has granted a number of special authorizations to some Canadian radio amateurs to conduct experiments in the band 135.7 – 137.8 kHz and at 5 MHz. These experiments have had, as one objective, the provision of data that would support the objectives of RAC and the IARU for possible new allocations to the Amateur Service at these frequencies.
In accordance with the agreement between RAC and Industry Canada, all the special authorizations to Canadian radio amateurs will be terminated and transmissions must cease as of 30 June, 2007.
