DMRAA member KØHTF brought the following to our attention:

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 go into effect on 01 January 2009 at 00:00 UTC. More info can be found here.

Thanks, Doc, for letting us know of the change.
