Una notizia dalla lista UDXF che riguardanta il campo di frequenza della stazione di tempo e frequenza CHU dal Canada (attiva anche su 14670 kHz e 3330 kHz)
CHU Moving to 7850 kHz
After seventy years of broadcasting Canada's official time, radio station CHU will move from 7335 KHz to 7850 KHz. The change goes into effect on 01 January 2009 at 00:00 UTC.
In April 2007, the International Telecommunications Union re-allocated the 7300-7350 KHz band from "fixed service" to broadcasting. Since then, interference on the 7335 KHz frequency has come from many broadcasters around the world, prompting CHU's move (From CQ Magazine)
