Canadian time/frequency standard station CHU -- a fixture for decades
on 7335 kHz -- will change frequency to 7850 kHz at 0000 UTC on
January 1, 2009. The move comes as a result of the International
Telecommunication Union's decision in 2007 to expand the 40-meter ham
band in Europe and Africa (Region I) to 7000-7200 kHz. It was
previously 7000-7100 kHz, with -- as every 40-meter DXer knows --
international broadcasting allocated from 7100-7300 kHz.
As part of the 40-meter expansion, the international broadcast band
was shifted to 7200-7350 kHz. As broadcasters began relocating, CHU
on 7335 began experiencing significant interference. Thus, officials
at Canada's National Research Council, which operates CHU, decided to
move the time/frequency standard station's transmissions to 7850 kHz
as of the beginning of 2009. The complete NRC announcement (English
version) is online at
