> CHANGE YOUR SHORTWAVE RADIO DIAL
>
> After seventy years of broadcasting Canada's official time, NRC's
> shortwave station CHU will move the transmission frequency for the 7335
kHz
> transmitter to 7850 kHz. The change will occur on 01 January 2009 at 0000
> UTC.
>
> CHU is a part of NRC's system for disseminating official time throughout
> Canada, broadcasting 24 hours a day from a location approximately 20 km
> south-west of Ottawa. Listeners hear tones to mark the seconds, voice to
> announce the time in French and English, and digital data to set
computers.
>
> The atomic clocks at CHU are part of the ensemble of clocks in the time
and
> frequency research laboratories in Ottawa, at the National Research
Council
> Canada. The NRC clocks are used in conjunction with clocks in the time
> laboratories of other countries to construct the internationally accepted
> scale of time, UTC (Coordinated Universal Time), which is now the
reference
> for official time used by all countries. UTC is the modern implementation
> of Greenwich Mean Time.
>
> "Coincidentally, this frequency change comes at a time when NRC is
> investing resources to refurbish the aging transmitters at CHU in order to
> provide clear, dependable shortwave services as part of NRC's mandate to
> disseminate time to all Canadians." said Ray Pelletier, Technical Officer
> at the NRC-Institute for National Measurement Standards, who oversees the
> CHU facility "The shortwave time service is especially beneficial for
those
> in remote locations where there is limited access to internet and
telephone
> communication. CHU also provides a back up against failure of other
> services."
>
> In April 2007, the International Telecommunications Union re-allocated the
> 7300-7350 KHz band from a fixed service to a broadcasting service. Since
> then, interference on the 7335 KHz frequency has come from many
information
> broadcasters around the world.
>
> CHU listeners in Canada and around the world who have for so long
> considered the 7335 kHz frequency exclusively for time signals, are very
> vocal about this interference. We have heard from amateur radio operators,
> watchmakers, astronomers, and navigators who use the tones and voice
> signals. As well, comments were received from those who use the carrier as
> a calibration source at a distance for their equipment.
>
> To give notice to users, CHU will broadcast an announcement in both
> English and French. More information can be found at
> http://www.nrc-cnrc.gc.ca/main_e.html and
> http://www.nrc-cnrc.gc.ca/main_f.html
>
> Comments about the CHU change can be sent by e-mail to
> radio.chu@...
> (Raymond Pelletier, CHU, DX LISTENING DIGEST)

> As of Dec 9, nothing at above site about 7850. This NRC website also
> mentions a leap second to be added at the end of 2008y:
> http://time5.nrc.ca/timefreq/bulletin_tf-b.html (gh)
>
> Monitored around 1430 UT Dec 9 on 7335, no announcements being heard yet
> about the frequency change or the leap second.
